# 课件怎么放
|
||||
|
||||
学生打开导航里的「课件」，点进去就能直接翻 PPT。不需要导出图片，也不需要后台上传。
|
||||
|
||||
把 PowerPoint 文件放进**仓库根目录**的 `courseware/`，用 git 提交：
|
||||
|
||||
```
|
||||
courseware/2.2 数组的插入与删除.pptx
|
||||
courseware/3.1 原码反码补码.pptx
|
||||
```
|
||||
|
||||
目录里每一个 `.pptx` 就是一课，文件名就是标题。网页不能直接访问这个目录；播放器通过 `courseware-file.php` 读取文件。
|
||||
|
||||
请用 **`.pptx`**（PowerPoint 2007 及以后）。旧的 `.ppt` 请在 PowerPoint 里「另存为 → pptx」再提交。
|
||||
|
||||
动画、特殊字体、SmartArt 在网页里可能和上课投影不完全一样，但可以翻页看内容。

# 2.2 数组的插入与删除
|
||||
|
||||
---
|
||||
|
||||
## 一、先把数组想成一排固定座位
|
||||
|
||||
今天我们只学两件事：
|
||||
|
||||
- 往数组里放进一个新元素，这叫**插入**。
|
||||
- 从数组里拿走一个元素，这叫**删除**。
|
||||
|
||||
数组可以想成教室里一排**紧紧挨着的固定座位**，每个位置都不能乱跳。
|
||||
|
||||
比如下面这个数组：
|
||||
|
||||
| 位置（第几个） | 第1个 | 第2个 | 第3个 | 第4个 | 第5个 |
|
||||
|:---:|:---:|:---:|:---:|:---:|:---:|
|
||||
| 下标 | 0 | 1 | 2 | 3 | 4 |
|
||||
| 内容 | 12 | 18 | 23 | 31 | 40 |
|
||||
|
||||
这里要特别注意：
|
||||
|
||||
- 平时说“第 1 个位置、第 2 个位置”，是按照人的习惯数的。
|
||||
- 在 C++ 数组里，下标从 `0` 开始。
|
||||
|
||||
所以：
|
||||
|
||||
- 第 1 个位置，对应下标 `0`
|
||||
- 第 3 个位置，对应下标 `2`
|
||||
- 第 `pos` 个位置，对应下标 `pos - 1`
|
||||
|
||||
> 这节课讲图的时候，我们主要说“第几个位置”；写代码的时候，再换成下标。
|
||||
|
||||
---
|
||||
|
||||
## 二、为什么数组的插入和删除要“搬家”？
|
||||
|
||||
数组里的元素是**连续排在一起**的。
|
||||
|
||||
这就像一排已经坐好的同学：
|
||||
|
||||
- 想在中间插入一个人，就得有人挪一挪，腾出空位。
|
||||
- 想删掉中间一个人，就会空出一个洞，后面的人要补上来。
|
||||
|
||||
所以数组的插入和删除，最关键的不是“放进去”或“拿出来”，而是：
|
||||
|
||||
> **怎样移动其他元素，才能既不丢数据，也不弄乱顺序。**
|
||||
|
||||
这就是本节最重要的地方。
|
||||
|
||||
---
|
||||
|
||||
## 三、数组插入：先腾位置，再放新元素
|
||||
|
||||
### 1. 例子：在第 3 个位置插入 20
|
||||
|
||||
原数组：
|
||||
|
||||
```text
|
||||
位置： 1 2 3 4 5 6
|
||||
内容： [12] [18] [23] [31] [40] [ ]
|
||||
```
|
||||
|
||||
注意：这里第 6 个位置先留空，表示数组容量足够大，可以插入新元素。
|
||||
|
||||
现在要把 `20` 插入到**第 3 个位置**。
|
||||
|
||||
插入后应该变成：
|
||||
|
||||
```text
|
||||
位置： 1 2 3 4 5 6
|
||||
内容： [12] [18] [20] [23] [31] [40]
|
||||
```
|
||||
|
||||
### 2. 插入时，元素是怎样移动的？
|
||||
|
||||
要想让第 3 个位置空出来，原来第 3、4、5 个位置上的元素都要向后移动一格。
|
||||
|
||||
但一定要记住：
|
||||
|
||||
> **插入时，要从后往前移。**
|
||||
|
||||
移动过程如下：
|
||||
|
||||
```text
|
||||
原来： [12] [18] [23] [31] [40] [ ]
|
||||
第1步： [12] [18] [23] [31] [40] [40] 把 40 往后移
|
||||
第2步： [12] [18] [23] [31] [31] [40] 把 31 往后移
|
||||
第3步： [12] [18] [23] [23] [31] [40] 把 23 往后移
|
||||
第4步： [12] [18] [20] [23] [31] [40] 把 20 放进第 3 个位置
|
||||
```
|
||||
|
||||
### 3. 为什么插入要从后往前移？
|
||||
|
||||
因为如果你从前往后移，前面的数据会把后面的数据盖掉。
|
||||
|
||||
来看一个错误示范。还是在第 3 个位置插入 `20`：
|
||||
|
||||
```text
|
||||
原来： [12] [18] [23] [31] [40] [ ]
|
||||
|
||||
错误地从前往后移：
|
||||
第1步： [12] [18] [23] [23] [40] [ ]
|
||||
第2步： [12] [18] [23] [23] [23] [ ]
|
||||
第3步： [12] [18] [23] [23] [23] [23]
|
||||
```
|
||||
|
||||
你会发现：原来的 `31` 和 `40` 都不见了！
|
||||
|
||||
原因是：
|
||||
|
||||
- 你先把 `23` 复制到了后面。
|
||||
- 后面的位置被改掉以后，再继续搬，就只能搬到已经改坏的数据。
|
||||
|
||||
所以插入时一定要：
|
||||
|
||||
> **从最后一个元素开始，倒着往前挪。**
|
||||
|
||||
### 4. 插入的步骤口诀
|
||||
|
||||
可以记成一句话：
|
||||
|
||||
> **先留空，从后搬，最后放。**
|
||||
|
||||
具体就是：
|
||||
|
||||
1. 先保证数组后面有空位置。
|
||||
2. 从最后一个元素开始，依次向后移动一格。
|
||||
3. 移到目标位置后停下。
|
||||
4. 把新元素放进去。
|
||||
5. 数组长度 `n` 加 1。
|
||||
|
||||
### 5. 插入的课堂版 C++ 代码
|
||||
|
||||
下面的代码约定：
|
||||
|
||||
- 数组现在有 `n` 个元素。
|
||||
- 要把 `x` 插入到第 `pos` 个位置。
|
||||
- `pos` 从 `1` 开始数。
|
||||
- 数组容量足够大。
|
||||
|
||||
```cpp
|
||||
for (int i = n; i >= pos; i--) {
|
||||
a[i] = a[i - 1];
|
||||
}
|
||||
a[pos - 1] = x;
|
||||
n++;
|
||||
```
|
||||
|
||||
你可以这样理解这段循环：
|
||||
|
||||
- `i = n` 时，把最后一个元素搬到新位置。
|
||||
- `i = n - 1` 时，把倒数第二个元素往后搬。
|
||||
- 一直搬到第 `pos` 个位置为止。
|
||||
|
||||
---
|
||||
|
||||
## 四、数组删除：先补空位，再缩短长度
|
||||
|
||||
### 1. 例子：删除第 3 个位置的元素
|
||||
|
||||
原数组：
|
||||
|
||||
```text
|
||||
位置： 1 2 3 4 5
|
||||
内容： [ 8] [11] [14] [17] [20]
|
||||
```
|
||||
|
||||
现在要删除第 3 个位置上的 `14`。
|
||||
|
||||
删除后应该变成：
|
||||
|
||||
```text
|
||||
位置： 1 2 3 4
|
||||
内容： [ 8] [11] [17] [20]
|
||||
```
|
||||
|
||||
### 2. 删除时，元素是怎样移动的？
|
||||
|
||||
第 3 个位置删掉以后，会空出一个位置。后面的元素要依次往前补。
|
||||
|
||||
注意：
|
||||
|
||||
> **删除时，要从前往后移。**
|
||||
|
||||
移动过程如下：
|
||||
|
||||
```text
|
||||
原来： [ 8] [11] [14] [17] [20]
|
||||
第1步： [ 8] [11] [17] [17] [20] 把 17 往前移
|
||||
第2步： [ 8] [11] [17] [20] [20] 把 20 往前移
|
||||
最后： [ 8] [11] [17] [20] 长度减 1
|
||||
```
|
||||
|
||||
最后那个多出来的 `20` 虽然还留在原来的地方，但因为数组长度已经减 1，所以它已经**不算数组的一部分了**。
|
||||
|
||||
### 3. 为什么删除要从前往后移？
|
||||
|
||||
因为空位在前面，应该让后面的元素一个一个补上来。
|
||||
|
||||
如果你反过来，从后往前移，也会出问题。还是删除第 3 个位置：
|
||||
|
||||
```text
|
||||
原来： [ 8] [11] [14] [17] [20]
|
||||
|
||||
错误地从后往前移：
|
||||
第1步： [ 8] [11] [14] [20] [20]
|
||||
第2步： [ 8] [11] [20] [20] [20]
|
||||
```
|
||||
|
||||
原来的 `17` 被弄丢了。
|
||||
|
||||
所以删除时要记住：
|
||||
|
||||
> **从缺口的后面开始，按顺序往前补。**
|
||||
|
||||
### 4. 删除的步骤口诀
|
||||
|
||||
可以记成一句话：
|
||||
|
||||
> **先删掉，从前搬，最后减。**
|
||||
|
||||
具体就是：
|
||||
|
||||
1. 找到要删除的位置。
|
||||
2. 让后面的元素依次向前移动一格。
|
||||
3. 数组长度 `n` 减 1。
|
||||
|
||||
### 5. 删除的课堂版 C++ 代码
|
||||
|
||||
下面的代码约定：
|
||||
|
||||
- 数组现在有 `n` 个元素。
|
||||
- 删除第 `pos` 个位置上的元素。
|
||||
- `pos` 从 `1` 开始数。
|
||||
|
||||
```cpp
|
||||
for (int i = pos; i < n; i++) {
|
||||
a[i - 1] = a[i];
|
||||
}
|
||||
n--;
|
||||
```
|
||||
|
||||
你可以这样理解这段循环：
|
||||
|
||||
- `i = pos` 时，把后一个元素补到空位上。
|
||||
- `i = pos + 1` 时，再把更后面的元素补上来。
|
||||
- 一直补到最后一个元素为止。
|
||||

||||

|
||||
|
||||
## 五、插入和删除放在一起比较
|
||||
|
||||
| 操作 | 会发生什么 | 正确移动方向 | 为什么 |
|
||||
|:---:|:---|:---:|:---|
|
||||
| 插入 | 中间要腾出一个空位 | 从后往前 | 先保护后面的数据，不让它们被覆盖 |
|
||||
| 删除 | 中间会出现一个缺口 | 从前往后 | 让后面的数据按顺序补上来 |
|
||||
|
||||
再记一遍：
|
||||
|
||||
- **插入：从后往前移**
|
||||
- **删除：从前往后移**
|
||||
|
||||
这是本节最重要的结论。
|
||||
|
||||
---
|
||||
|
||||
## 六、两个最容易忽略的小细节
|
||||
|
||||
### 1. 插入前，数组要有空位
|
||||
|
||||
如果数组已经装满了，就不能直接插入。
|
||||
|
||||
比如数组最多只能放 5 个数，现在已经有 5 个数了，再插入第 6 个，就没有地方放了。
|
||||
|
||||
所以写程序时，常常会这样做：
|
||||
|
||||
- 开一个更大的数组，比如最多放 `100` 个数。
|
||||
- 实际已经用了多少个，用变量 `n` 记录。
|
||||
|
||||
### 2. 删除后，不是把数“擦掉”，而是把长度减 1
|
||||
|
||||
数组删除一个元素后，最后那个位置里可能还保留着旧数值，但这已经不重要了。
|
||||
|
||||
因为程序只看前 `n` 个元素：
|
||||
|
||||
- 删除前看前 `n` 个
|
||||
- 删除后只看前 `n - 1` 个
|
||||
|
||||
所以真正关键的是：
|
||||
|
||||
> **长度变了，数组有效范围也变了。**
|
||||
|
||||
---
|
||||
|
||||
## 七、特殊情况也要会判断
|
||||
|
||||
### 1. 在最后面插入
|
||||
|
||||
如果要在第 `n + 1` 个位置插入，也就是直接接到数组末尾：
|
||||
|
||||
```text
|
||||
[12] [18] [23] [31] [40] -> [12] [18] [23] [31] [40] [50]
|
||||
```
|
||||
|
||||
这时不需要搬动任何元素，直接放进去即可。
|
||||
|
||||
### 2. 删除最后一个元素
|
||||
|
||||
如果删除的是最后一个元素：
|
||||
|
||||
```text
|
||||
[12] [18] [23] [31] [40] -> [12] [18] [23] [31]
|
||||
```
|
||||
|
||||
这时也不需要搬动任何元素，只要把长度减 1 就行。
|
||||
|
||||
---
|
||||
|
||||
## 八、最容易犯的 5 个错误
|
||||
|
||||
### 错误 1：插入时移动方向写反
|
||||
|
||||
结果：后面的数据会被覆盖。
|
||||
|
||||
### 错误 2：删除时移动方向写反
|
||||
|
||||
结果：中间的数据会丢失。
|
||||
|
||||
### 错误 3：忘记更新 `n`
|
||||
|
||||
插入后忘记 `n++`，新元素虽然放进去了，但程序可能不把它算进去。
|
||||
|
||||
删除后忘记 `n--`，旧数据虽然应该消失了，但程序还会把它输出出来。
|
||||
|
||||
### 错误 4：把“第几个位置”和“下标”搞混
|
||||
|
||||
记住：
|
||||
|
||||
- 第 `1` 个位置，对应下标 `0`
|
||||
- 第 `pos` 个位置，对应下标 `pos - 1`
|
||||
|
||||
### 错误 5：插入时没有预留空间
|
||||
|
||||
结果：数组越界，程序可能出错。
|
||||
|
||||

|
||||
|
||||
## 九、一张总图记住本节内容
|
||||
|
||||
```text
|
||||
数组插入：先腾空位
|
||||
|
||||
[12] [18] [23] [31] [40] [ ]
|
||||
← ← ←
|
||||
[12] [18] [20] [23] [31] [40]
|
||||
|
||||
|
||||
数组删除：先补缺口
|
||||
|
||||
[ 8] [11] [14] [17] [20]
|
||||
→ →
|
||||
[ 8] [11] [17] [20]
|
||||
```
|
||||
|
||||
记忆口诀：
|
||||
|
||||
> **插入看后面，从后往前搬；删除看前面，从前往后搬。**
|
||||

|
||||
|
||||
## 十、课堂版完整示例
|
||||
|
||||
下面是一份把“插入”和“删除”都写进去的课堂版程序。为了简单起见，输入位置 `pos` 按“第几个位置”来理解，也就是从 `1` 开始数。
|
||||
|
||||
```cpp
|
||||
#include <bits/stdc++.h>
|
||||
using namespace std;
|
||||
|
||||
const int MAXN = 105;
|
||||
int a[MAXN];
|
||||
int n;
|
||||
|
||||
void insertValue(int pos, int x) {
|
||||
for (int i = n; i >= pos; i--) {
|
||||
a[i] = a[i - 1];
|
||||
}
|
||||
a[pos - 1] = x;
|
||||
n++;
|
||||
}
|
||||
|
||||
void deleteValue(int pos) {
|
||||
for (int i = pos; i < n; i++) {
|
||||
a[i - 1] = a[i];
|
||||
}
|
||||
n--;
|
||||
}
|
||||
|
||||
int main() {
|
||||
cin >> n;
|
||||
for (int i = 0; i < n; i++) {
|
||||
cin >> a[i];
|
||||
}
|
||||
|
||||
int pos, x;
|
||||
cin >> pos >> x;
|
||||
insertValue(pos, x);
|
||||
|
||||
for (int i = 0; i < n; i++) {
|
||||
cout << a[i] << " ";
|
||||
}
|
||||
cout << "\n";
|
||||
|
||||
cin >> pos;
|
||||
deleteValue(pos);
|
||||
|
||||
for (int i = 0; i < n; i++) {
|
||||
cout << a[i] << " ";
|
||||
}
|
||||
cout << "\n";
|
||||
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 十一、自己试一试
|
||||
|
||||
### 1. 观察移动过程
|
||||
|
||||
把 `9` 插入到下面数组的第 2 个位置，请你把每一步移动都画出来：
|
||||
|
||||
```text
|
||||
[3] [7] [12] [15] [ ]
|
||||
```
|
||||
|
||||
### 2. 观察删除过程
|
||||
|
||||
删除下面数组的第 4 个位置，请你把每一步移动都画出来：
|
||||
|
||||
```text
|
||||
[5] [8] [11] [14] [20]
|
||||
```
|
||||
|
||||
### 3. 想一想
|
||||
|
||||
- 为什么插入和删除都可能需要移动很多个元素？
|
||||
- 如果总是在数组最前面插入，会不会很麻烦？
|
||||
|
||||
如果你能清楚地回答这两个问题，就说明你已经真正理解数组的插入和删除了。

# 3.1 原码、反码与补码
|
||||
|
||||
---
|
||||
|
||||
## 一、先搞清楚：计算机为什么只认识 0 和 1？
|
||||
|
||||
你有没有想过，我们平时写下的数字 `5`、`-3`、`100`，计算机根本"看不懂"？
|
||||
|
||||
计算机的本质是**电路**。电路里的导线，要么**通电**，要么**断电**，只有两种状态。科学家就用 `1` 表示通电，用 `0` 表示断电。这就是**二进制**的由来。
|
||||
|
||||
**类比：** 想象一排电灯开关，每个开关只能「开」或「关」。用这一排开关，我们可以用不同的开/关组合来代表不同的数字——这就是二进制的核心思想。
|
||||
|
||||
| 十进制 | 二进制 |
|
||||
|:---:|:------:|
|
||||
| 0 | `0000` |
|
||||
| 1 | `0001` |
|
||||
| 2 | `0010` |
|
||||
| 3 | `0011` |
|
||||
| 5 | `0101` |
|
||||
| 7 | `0111` |
|
||||
|
||||
> **为什么不用十进制？**
|
||||
> 如果用十进制，每根导线需要精确区分 10 种不同的电压（0V、1V、2V……9V）。电路稍微受到干扰，电压抖动一点，数字就读错了。而二进制只需区分「高电压」和「低电压」两种情况，极难出错，制造成本也低得多。
|
||||
|
||||
---
|
||||
|
||||
## 二、正数好说，负数怎么办？
|
||||
|
||||
表示 `5` 很简单，写成 `0101` 就行。但 `-5` 呢？
|
||||
|
||||
计算机存数字时，会分配固定长度的空间，比如 **8位**（8个 0 或 1）。科学家想出了一个办法：
|
||||
|
||||
> **把最左边（最高位）那一位专门用来表示正负，叫"符号位"：**
|
||||
>
|
||||
> - `0` → 正数
|
||||
> - `1` → 负数
|
||||
|
||||
剩下的 7 位用来表示数值的大小。
|
||||
|
||||
这就是最朴素的方案——**原码**。
|
||||
|
||||
---
|
||||
|
||||
## 三、原码：最直观的方案
|
||||
|
||||
### 规则
|
||||
|
||||
- **正数：** 符号位写 `0`，后面写数值的二进制。
|
||||
- **负数：** 符号位写 `1`，后面写数值**绝对值**的二进制。
|
||||
|
||||
### 例子（8位）
|
||||
|
||||
| 十进制 | 原码 |
|
||||
|:----:|:-----------:|
|
||||
| `+5` | `0000 0101` |
|
||||
| `-5` | `1000 0101` |
|
||||
| `+0` | `0000 0000` |
|
||||
| `-0` | `1000 0000` |
|
||||
|
||||
直观，容易理解！但……
|
||||
|
||||
### 原码的两个大麻烦
|
||||
|
||||
**麻烦一：零有两个写法**
|
||||
|
||||
`+0` 写成 `0000 0000`，`-0` 写成 `1000 0000`，但它们其实是同一个数 `0`！这会让计算机很困惑——判断一个数是不是 `0` 时，要检查两种情况。
|
||||
|
||||
**麻烦二：加减法会算错**
|
||||
|
||||
用原码做 `5 + (-5)`，把两个原码直接相加：
|
||||
|
||||
```
|
||||
0000 0101 (+5 的原码)
|
||||
+ 1000 0101 (-5 的原码)
|
||||
-----------
|
||||
1000 1010 ← 这是 -10 的原码，答案错了！
|
||||
```
|
||||
|
||||
正确答案应该是 `0`，结果算出了 `-10`。这意味着计算机必须专门写一套特殊的判断逻辑来处理负数加法，硬件电路会变得很复杂。
|
||||
|
||||
---
|
||||
|
||||
## 四、反码：改进的尝试
|
||||
|
||||
### 规则
|
||||
|
||||
- **正数：** 反码与原码**完全相同**。
|
||||
- **负数：** 符号位保持 `1` 不变，其余 7 位**全部翻转**（`0` 变 `1`，`1` 变 `0`）。
|
||||
|
||||
### 例子（8位）
|
||||
|
||||
| 十进制 | 原码 | 反码 |
|
||||
|:----:|:-----------:|:-----------:|
|
||||
| `+5` | `0000 0101` | `0000 0101` |
|
||||
| `-5` | `1000 0101` | `1111 1010` |
|
||||
|
||||
### 用反码再试试 `5 + (-5)`
|
||||
|
||||
```
|
||||
0000 0101 (+5 的反码)
|
||||
+ 1111 1010 (-5 的反码)
|
||||
-----------
|
||||
1111 1111 ← 这是反码，对应的真值是 -0
|
||||
```
|
||||
|
||||
结果是 `1111 1111`，这个反码代表 `-0`。虽然不是理想的 `0000 0000`，但至少方向对了——运算逻辑有所改进。
|
||||
|
||||
### 反码还剩下的问题
|
||||
|
||||
零**依然有两种写法**：
|
||||
|
||||
- `0000 0000` = `+0` 的反码
|
||||
- `1111 1111` = `-0` 的反码
|
||||
|
||||
问题没有根本解决，只是往前走了一步。
|
||||
|
||||
---
|
||||
|
||||
## 五、补码：现代计算机真正使用的方案
|
||||
|
||||
### 规则
|
||||
|
||||
- **正数：** 补码与原码**完全相同**。
|
||||
- **负数：** 先求反码，再在最末位**加 1**。
|
||||
|
||||
### 一步步求 `-5` 的补码（8位）
|
||||
|
||||
```
|
||||
第一步：写出 -5 的原码
|
||||
1000 0101
|
||||
|
||||
第二步：符号位不变，其余位取反（得到反码）
|
||||
1111 1010
|
||||
|
||||
第三步：反码末位加 1（得到补码）
|
||||
1111 1010
|
||||
+ 1
|
||||
-----------
|
||||
1111 1011 ← 这就是 -5 的补码
|
||||
```
|
||||
|
||||
### 例子（8位）
|
||||
|
||||
| 十进制 | 原码 | 反码 | 补码 |
|
||||
|:----:|:-----------:|:-----------:|:-------------:|
|
||||
| `+5` | `0000 0101` | `0000 0101` | `0000 0101` |
|
||||
| `-5` | `1000 0101` | `1111 1010` | `1111 1011` |
|
||||
| `+0` | `0000 0000` | `0000 0000` | `0000 0000` |
|
||||
| `-0` | `1000 0000` | `1111 1111` | `0000 0000` ✓ |
|
||||
|
||||
> **神奇的事情：** `-0` 的反码 `1111 1111` 加 `1`，得到 `1 0000 0000`，共 9 位！但我们只保留 8 位，最高位的 `1` 自动丢弃，结果就是 `0000 0000`。这样正负零合并为同一个编码了！
|
||||
|
||||
### 用补码验证 `5 + (-5)`
|
||||
|
||||
```
|
||||
0000 0101 (+5 的补码)
|
||||
+ 1111 1011 (-5 的补码)
|
||||
-----------
|
||||
1 0000 0000 ← 产生了进位，但只保留低 8 位
|
||||
|
||||
结果 = 0000 0000 = 0 ✓ 正确！
|
||||
```
|
||||
|
||||
### 再验证 `7 + (-3)`（答案应为 4）
|
||||
|
||||
```
|
||||
0000 0111 (+7 的补码)
|
||||
+ 1111 1101 (-3 的补码)
|
||||
-----------
|
||||
1 0000 0100 ← 低 8 位是 0000 0100 = +4 ✓
|
||||
```
|
||||
|
||||
补码让**减法可以用加法来做**，计算机只需要一个加法器就够了，硬件设计大大简化！
|
||||
|
||||
---
|
||||
|
||||
## 六、三种编码方式总结
|
||||
|
||||
| | 原码 | 反码 | 补码 |
|
||||
|:------------:|:-----------:|:-------------:|:---------------:|
|
||||
| **正数规则** | 符号位 0 + 绝对值 | 同原码 | 同原码 |
|
||||
| **负数规则** | 符号位 1 + 绝对值 | 原码各位取反（符号位除外） | 反码 + 1 |
|
||||
| **零的表示** | 两种（正零/负零） | 两种（正零/负零） | 一种（唯一） |
|
||||
| **能否直接做加减法** | ✗ 不能 | 部分改善 | ✓ 可以 |
|
||||
| **8位表示范围** | -127 ~ +127 | -127 ~ +127 | **-128 ~ +127** |
|
||||
|
||||
> **补码能多表示一个负数**，原因是消灭了 `-0`，空出来的编码 `1000 0000` 就用来表示 `-128`。
|
||||
|
||||
---
|
||||
|
||||
## 七、补码的"逆运算"：已知补码求原来的数
|
||||
|
||||
如果拿到一个**负数的补码**，怎么还原成十进制？
|
||||
|
||||
**方法：对补码再做一次"取反加一"即可。**
|
||||
|
||||
**例：** 已知某数的 8 位补码为 `1111 1011`，求它是多少？
|
||||
|
||||
```
|
||||
第一步：末位加 1（取反加一 = 再做一次补码运算）
|
||||
1111 1011 →（取反）→ 1000 0100 →（加1）→ 1000 0101
|
||||
|
||||
第二步：读结果：符号位为 1（负数），数值部分为 0000 0101 = 5
|
||||
|
||||
结论：1111 1011 这个补码表示的是 -5。
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 八、用 C++ 实现原码、反码、补码的输出
|
||||
|
||||
学完了手算方法，我们来用 C++ 写一个程序，让计算机自动完成这些步骤。
|
||||
|
||||
### 核心思路
|
||||
|
||||
用一个长度为 8 的 `int` 数组来表示 8 位二进制，**下标 0 存最低位，下标 7 存符号位（最高位）**。
|
||||
|
||||
- **原码**：先把绝对值不断除以 2 取余数，填入数组；再把下标 7 设为符号位（正数为 0，负数为 1）。
|
||||
- **反码**：正数与原码相同；负数把除符号位以外的每一位取反（`0` 变 `1`，`1` 变 `0`，即 `1 - bit`）。
|
||||
- **补码**：正数与原码相同；负数在反码的基础上加 1，用"逐位进位"模拟加法。
|
||||
|
||||
### 代码
|
||||
|
||||
```cpp
|
||||
#include <bits/stdc++.h>
|
||||
using namespace std;
|
||||
|
||||
// 将非负整数 n（0~127）的二进制填入数组 bits[]
|
||||
// bits[0] 是最低位，bits[7] 是最高位（符号位）
|
||||
void fillBits(int n, int bits[8]) {
|
||||
for (int i = 0; i < 8; i++) {
|

void printBits(int bits[8]) {
|

for (int i = 7; i >= 0; i--) {
|
||||
cout << bits[i];
|

fillBits(n, original);
|
||||
// 正数：三种编码完全相同
|
||||
for (int i = 0; i < 8; i++) {
|
||||
inverse[i] = original[i];
|
||||
complement[i] = original[i];
|
||||
}
|
||||
} else {
|
||||
// 原码：绝对值的二进制，符号位设为 1
|
||||
fillBits(-n, original);
|
||||
original[7] = 1;
|
||||
|
||||
// 反码：符号位不变，其余位取反
|
||||
inverse[7] = 1;
|
||||
for (int i = 0; i < 7; i++) {
|
||||
inverse[i] = 1 - original[i];
|
||||
}
|
||||
|
||||
// 补码：反码加 1，模拟手动进位
|
||||
int carry = 1;
|
||||
for (int i = 0; i < 8; i++) {
|
||||
int sum = inverse[i] + carry;
|
||||
complement[i] = sum % 2;
|
||||
carry = sum / 2;
|
||||
}
|
||||
}
|
||||
|
||||

|
||||
cout << "反码: "; printBits(inverse);
|
||||

|
||||
|
||||
int main() {
|
||||
int n;
|
||||
cin >> n;
|
||||
|
||||
if (n < -127 || n > 127) {
|
||||
cout << "请输入 -127 到 127 之间的整数！" << endl;
|
||||
return 0;
|
||||
}
|
||||
|
||||
cout << "n = " << n << endl;
|
||||
showCodes(n);
|
||||
return 0;
|
||||
}
|
||||
```
|
||||
|
||||
### 运行示例
|
||||
|
||||
输入 `-5`，输出：
|
||||
|
||||
```
|
||||
n = -5
|
||||
原码: 1000 0101
|
||||
反码: 1111 1010
|
||||
补码: 1111 1011
|
||||
```
|
||||
|
||||
输入 `5`，输出：
|
||||
|
||||
```
|
||||
n = 5
|
||||
原码: 0000 0101
|
||||
反码: 0000 0101
|
||||
补码: 0000 0101
|
||||
```
|
||||
|
||||
### 关键代码讲解
|
||||
|
||||
**① `fillBits`：把整数转为二进制数组**
|
||||
|
||||
```
|
||||
n = 5：
|
||||
5 % 2 = 1 → bits[0] = 1, n = 5/2 = 2
|
||||
2 % 2 = 0 → bits[1] = 0, n = 2/2 = 1
|
||||
1 % 2 = 1 → bits[2] = 1, n = 1/2 = 0
|
||||
其余位全为 0
|
||||
```
|
||||
|
||||
这就是"短除法"的代码版本，与手算完全一致。
|
||||
|
||||
**② `inverse[i] = 1 - original[i]`：取反**
|
||||
|
||||
- `original[i]` 是 0 时，`1 - 0 = 1`；
|
||||
- `original[i]` 是 1 时，`1 - 1 = 0`。
|
||||
|
||||
不需要任何特殊符号，普通减法就能完成翻转。
|
||||
|
||||
**③ 反码加 1 的进位模拟**
|
||||
|
||||
```
|
||||
假设反码是 1111 1010，加 1：
|
||||
carry = 1
|
||||
i=0: 0+1=1, bits=1, carry=0
|
||||
i=1: 1+0=1, bits=1, carry=0
|
||||
...（carry 已为 0，后续不变）
|
||||
结果：1111 1011 ← 这正是 -5 的补码
|
||||
```
|
||||
|
||||
用 `sum % 2` 取本位，`sum / 2` 取进位，完全模拟了手算的竖式加法。
|
||||
|
||||
> **想一想：** 为什么范围限制在 `-127` 到 `127`，而不包括 `-128`？
|
||||
> 因为 `-128` 没有合法的 8 位**原码**（8 位原码最多表示 `-127`），只有**补码**能表示它（`1000 0000`）。你可以尝试修改代码，增加对 `-128` 的特殊处理。

# 3.2 二进制运算
|
||||
|
||||
---
|
||||
|
||||
## 一、为什么还要学“二进制运算”？
|
||||
|
||||
在上一节里，我们已经知道了计算机用二进制存数，也知道了补码能把减法变成加法。接下来要学的是：
|
||||
|
||||
- 按位与（AND）
|
||||
- 按位或（OR）
|
||||
- 按位非（NOT）
|
||||
- 按位异或（XOR）
|
||||
- 左移（`<<`）
|
||||
- 右移（`>>`）
|
||||
- 二进制加法
|
||||
- 二进制减法
|
||||
|
||||
这些运算不是“冷知识”，而是程序里常见的底层工具：权限开关、状态压缩、快速比较、数据校验都会用到。
|
||||
|
||||
---
|
||||
|
||||
## 二、先记住 6 个位运算
|
||||
|
||||
设两个二进制位分别是 $a$ 和 $b$，每一位只可能是 0 或 1。
|
||||
|
||||
### 1. 按位与 AND（符号 `&`）
|
||||
|
||||
规则：只有两位都为 1，结果才是 1。
|
||||
|
||||
| a | b | a & b |
|
||||
|:---:|:---:|:-----:|
|
||||
| 0 | 0 | 0 |
|
||||
| 0 | 1 | 0 |
|
||||
| 1 | 0 | 0 |
|
||||
| 1 | 1 | 1 |
|
||||
|
||||
可以理解为“都同意才通过”。
|
||||
|
||||
### 2. 按位或 OR（符号 `|`）
|
||||
|
||||
规则：只要有一位是 1，结果就是 1。
|
||||
|
||||
| a | b | a \| b |
|
||||
|:---:|:---:|:------:|
|
||||
| 0 | 0 | 0 |
|
||||
| 0 | 1 | 1 |
|
||||
| 1 | 0 | 1 |
|
||||
| 1 | 1 | 1 |
|
||||
|
||||
可以理解为“有人同意就通过”。
|
||||
|
||||
### 3. 按位非 NOT（符号 `~`，一元运算）
|
||||
|
||||
规则：0 变 1，1 变 0。
|
||||
|
||||
| a | ~a |
|
||||
|:---:|:---:|
|
||||
| 0 | 1 |
|
||||
| 1 | 0 |
|
||||
|
||||
### 4. 按位异或 XOR（符号 `^`）
|
||||
|
||||
规则：两位不同为 1，相同为 0。
|
||||
|
||||
| a | b | a ^ b |
|
||||
|:---:|:---:|:-----:|
|
||||
| 0 | 0 | 0 |
|
||||
| 0 | 1 | 1 |
|
||||
| 1 | 0 | 1 |
|
||||
| 1 | 1 | 0 |
|
||||
|
||||
可以理解为“不同就亮灯”。
|
||||
|
||||
### 5. 左移（符号 `<<`）
|
||||
|
||||
规则：`x << k` 表示所有位向左移动 $k$ 位，右侧补 0。
|
||||
|
||||
- 在不溢出的情况下，数值相当于乘 $2^k$。
|
||||
- 固定 32 位时，左边移出去的高位会被丢弃。
|
||||
|
||||
例：8 位下 `00101101 << 2 = 10110100`。
|
||||
|
||||
### 6. 右移（符号 `>>`）
|
||||
|
||||
规则：`x >> k` 表示所有位向右移动 $k$ 位。
|
||||
|
||||
- 对无符号数，左侧补 0。
|
||||
- 对有符号数，很多语言会做“算术右移”（补符号位），所以课堂里先按无符号来理解更稳妥。
|
||||
|
||||
例：8 位下 `00101101 >> 3 = 00000101`。
|
||||
|
||||

|
||||
|
||||
## 三、C++ 里位运算的优先级（一定要加括号）
|
||||
|
||||
下面按 cppreference 的顺序，只保留“和计算最相关”的部分（第 5-7、9-15 级）：
|
||||
|
||||
| 优先级（高 -> 低） | 运算符 | 含义 | |
|
||||
|:-----------:|:----------------- |:----- |:---:|
|
||||
| 5 | `*` `/` `%` | 乘、除、模 | |
|
||||
| 6 | `+` `-` | 加、减 | |
|
||||
| 7 | `<<` `>>` | 左移、右移 | |
|
||||
| 9 | `<` `<=` `>` `>=` | 关系比较 | |
|
||||
| 10 | `==` `!=` | 相等比较 | |
|
||||
| 11 | `&` | 按位与 | |
|
||||
| 12 | `^` | 按位异或 | |
|
||||
| 13 | `\|` | 按位或 | |
|
||||
| 14 | `&&` | 逻辑与 | |
|
||||
| 15 | `\|\|` | 逻辑或 | |
|
||||
|
||||
看 5 个典型例子：
|
||||
|
||||
1) `a + b << 1`
|
||||
- 实际等价于 `(a + b) << 1`
|
||||
- 不是 `a + (b << 1)`
|
||||
2) `x | y & z`
|
||||
- 实际等价于 `x | (y & z)`
|
||||
- 不是 `(x | y) & z`
|
||||
3) `a ^ b & c`
|
||||
- 实际等价于 `a ^ (b & c)`
|
||||
- 不是 `(a ^ b) & c`
|
||||
4) `x + y > z`
|
||||
- 实际等价于 `(x + y) > z`
|
||||
- 不是 `x + (y > z)`
|
||||
5) `a & b == 0`
|
||||
- 实际等价于 `a & (b == 0)`（因为 `==` 高于 `&`）
|
||||
- 想判断“按位与结果是否为 0”，应写成 `(a & b) == 0`
|
||||
|
||||
课堂建议：只要一个表达式里混用了两类以上运算符，就主动加括号，别赌记忆。
|
||||
|
||||
---
|
||||
|
||||
## 四、位串上的运算：逐位独立进行
|
||||
|
||||
例如：
|
||||
|
||||
```
|
||||
a = 00101101
|
||||
b = 00010111
|
||||
```
|
||||
|
||||
逐位计算：
|
||||
|
||||
```
|
||||
a & b = 00000101
|
||||
a | b = 00111111
|
||||
a ^ b = 00111010
|
||||
~a = 11010010
|
||||
```
|
||||
|
||||
注意：`~a` 的结果长度和机器位数有关。课堂里我们常固定成 8 位或 32 位来讨论。
|
||||
|
||||
### 竖式写法示范（像小学列竖式）
|
||||
|
||||
把高位写在左边、低位写在右边，同一列对齐后逐列运算。
|
||||
|
||||
1) 按位与 `&`
|
||||
|
||||
```text
|
||||
0 0 1 0 1 1 0 1 (a)
|
||||
& 0 0 0 1 0 1 1 1 (b)
|
||||
----------------------
|
||||
0 0 0 0 0 1 0 1 (a & b)
|
||||
```
|
||||
|
||||
2) 按位或 `|`
|
||||
|
||||
```text
|
||||
0 0 1 0 1 1 0 1 (a)
|
||||
| 0 0 0 1 0 1 1 1 (b)
|
||||
----------------------
|
||||
0 0 1 1 1 1 1 1 (a | b)
|
||||
```
|
||||
|
||||
3) 按位异或 `^`
|
||||
|
||||
```text
|
||||
0 0 1 0 1 1 0 1 (a)
|
||||
^ 0 0 0 1 0 1 1 1 (b)
|
||||
----------------------
|
||||
0 0 1 1 1 0 1 0 (a ^ b)
|
||||
```
|
||||
|
||||
4) 左移与右移也可按“横向挪位”理解
|
||||
|
||||
```text
|
||||
a : 0 0 1 0 1 1 0 1
|
||||
a << 2 : 1 0 1 1 0 1 0 0 (左移两格，右侧补 0)
|
||||
a >> 3 : 0 0 0 0 0 1 0 1 (右移三格，左侧补 0)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 五、二进制加法与减法
|
||||
|
||||
### 1. 二进制加法
|
||||
|
||||
和十进制竖式一样，也是“本位求和 + 进位”。
|
||||
|
||||
单个位相加规则：
|
||||
|
||||
- $0+0=0$，进位 0
|
||||
- $0+1=1$，进位 0
|
||||
- $1+0=1$，进位 0
|
||||
- $1+1=0$，进位 1
|
||||
|
||||
如果再加上原来的进位，就变成三数相加。
|
||||
|
||||
竖式例子（8 位）：`00101101 + 00010111`
|
||||
|
||||
```text
|
||||
进位: 0 0 1 1 1 1 1
|
||||
0 0 1 0 1 1 0 1
|
||||
+ 0 0 0 1 0 1 1 1
|
||||
----------------------
|
||||
0 1 0 0 0 1 0 0
|
||||
```
|
||||
|
||||
可让学生从最右列开始，逐列写“本列结果位”和“向左进位”。
|
||||
|
||||
### 2. 二进制减法
|
||||
|
||||
可以按“借位法”逐位减，也可以用补码思想把减法变加法。
|
||||
|
||||
在本章练习里，统一按 **32 位无符号整数** 处理：
|
||||
|
||||
- 超过 $2^{32}-1$ 的高位进位丢弃
|
||||
- 不足 0 时按 32 位环绕（相当于加上 $2^{32}$）
|
||||
|
||||
竖式例子（8 位）：`00101101 - 00010111`
|
||||
|
||||
```text
|
||||
借位: 0 0 1 1 1 1 0
|
||||
0 0 1 0 1 1 0 1
|
||||
- 0 0 0 1 0 1 1 1
|
||||
----------------------
|
||||
0 0 0 1 0 1 1 0
|
||||
```
|
||||
|
||||
从最右列开始，若不够减就向左借 1（借 1 相当于当前位加 2）。
|
||||

## 六、C++：用数组模拟按位运算与加减
|
||||
|
||||
下面给一份课堂版代码：
|
||||
|
||||
```cpp
|
||||
#include <bits/stdc++.h>
|
||||
using namespace std;
|
||||
|
||||
const int LEN = 32;
|
||||
|
||||
// 把无符号整数转成二进制数组：bits[0] 是最低位
|
||||
void toBits(unsigned int x, int bits[]) {
|
||||
for (int i = 0; i < LEN; i++) {
|
||||
bits[i] = x % 2;
|
||||
x /= 2;
|
||||
}
|
||||
}
|
||||
|
||||
// 把二进制数组转回无符号整数
|
||||
unsigned int toUInt(const int bits[]) {
|
||||
unsigned int x = 0;
|
||||
for (int i = LEN - 1; i >= 0; i--) {

x = x * 2 + bits[i];
|

}
|

return x;
|
||||
}
|

|

// 打印 32 位二进制串（高位在前）
|
||||
void printBits(const int bits[]) {
|

for (int i = LEN - 1; i >= 0; i--) {
|

|

}
|
||||
|

// 32 位无符号加法：溢出进位自动丢弃
|
||||
void addBits(const int a[], const int b[], int c[]) {
|
||||
int carry = 0;
|
||||
for (int i = 0; i < LEN; i++) {
|
||||
int sum = a[i] + b[i] + carry;
|
||||
c[i] = sum % 2;
|
||||
carry = sum / 2;
|
||||
}
|
||||
}
|
||||
|
||||
// 32 位无符号减法：逐位借位
|
||||
void subBits(const int a[], const int b[], int c[]) {
|
||||
int borrow = 0;
|
||||
for (int i = 0; i < LEN; i++) {

} else {
|

c[i] = cur + 2;
|
||||
borrow = 1;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
int main() {
|
||||
unsigned int A, B;
|
||||
cin >> A >> B;
|
||||
|
||||
int a[LEN], b[LEN], c[LEN];
|
||||
toBits(A, a);
|
||||
toBits(B, b);
|
||||
|
||||
cout << "A = "; printBits(a);

|
||||
|
||||
### 【第五组】常用位技巧（探究题，重点）
|
||||
|
||||
这一组不要先背公式，先按题目把例子算出来，再归纳。
|
||||
|
||||
#### A. 探究“最低位 1”（lowbit）
|
||||
|
||||
对下面每个 `x`，先写出二进制，再计算 `-x`（按补码），最后算出 `x & (-x)`：
|
||||
|
||||
52. `x = 12`
|
||||
|
||||
53. `x = 40`
|
||||
|
||||
54. `x = 44`
|
||||
|
||||
55. `x = 72`
|
||||
|
||||
56. 观察 52-55 的结果，归纳一句话：`x & (-x)` 保留了 `x` 的哪一部分？
|
||||
|
||||
#### B. 探究“去掉最低位 1”
|
||||
|
||||
对下面每个 `x`，计算 `x - 1`，再算 `x & (x - 1)`：
|
||||
|
||||
57. `x = 12`
|
||||
|
||||
58. `x = 40`
|
||||
|
||||
59. `x = 44`
|
||||
|
||||
60. `x = 72`
|
||||
|
||||
61. 观察 57-60 的结果，归纳一句话：`x & (x-1)` 对二进制位做了什么变化？
|
||||
|
||||
#### C. 由例子得到“2 的幂”判定
|
||||
|
||||
分别计算 `x & (x - 1)`，并记录是否为 0：
|
||||
|
||||
62. `x = 1`
|
||||
|
||||
63. `x = 2`
|
||||
|
||||
64. `x = 4`
|
||||
|
||||
65. `x = 8`
|
||||
|
||||
66. `x = 3`
|
||||
|
||||
67. `x = 6`
|
||||
|
||||
68. 根据 62-67，总结：当 `x > 0` 时，什么条件等价于“`x` 是 2 的幂”？
|
||||
|
||||
#### D. 应用题（把结论用起来）
|
||||
|
||||
69. 不用循环，判断 `64` 是否是 2 的幂，并写出关键表达式值。
|
||||
70. 不用循环，判断 `72` 是否是 2 的幂，并写出关键表达式值。
|
||||
71. 设 `x = 01011000`（8 位），先求 `x & (-x)`，再给出最低位 1 的位置（最低位记第 0 位）。
|
||||
72. 设 `x = 00101000`（8 位），先求 `x & (-x)`，再给出最低位 1 的位置（最低位记第 0 位）。
|
||||
73. 设 `x = 10000000`（8 位），先求 `x & (-x)`，再给出最低位 1 的位置（最低位记第 0 位）。
|
||||
74. 从 `x = 90` 开始，反复执行 `x = x & (x - 1)` 直到变成 0，需要几步？由此得到 `90` 的二进制中有几个 1？
|
||||
75. 给定偶数 `n`，写出一个表达式快速判断它是否能被 4 整除，并说明对应的“二进制末尾特征”。

49. 唯一解 `x = 10101101`。
|

50. 可取 `y = 11100110`（只要在 `u` 为 1 的位上与 `v` 对齐即可，`u` 为 0 的位任意）。
|
||||
51. 不存在，因为按位或不会把 `u` 中的 1 变成 0，而 `u = 00110110` 在第 5、4、2、1 位已有 1，但 `v = 00000110` 在第 5、4 位是 0。
|
||||
|
||||
**第五组**
|
||||
|
||||
52. `12 = 1100`，`-12`（8 位）是 `11110100`，`12 & (-12) = 0100`（十进制 4）
|
||||
53. `40 = 101000`，`40 & (-40) = 001000`（十进制 8）

|
||||
55. `72 = 1001000`，`72 & (-72) = 0001000`（十进制 8）
|
||||
56. 结论：`x & (-x)` 只保留最低位的 1，其余位清零（即 lowbit）
|
||||
57. `12 & 11 = 1100 & 1011 = 1000`（十进制 8）
|
||||
58. `40 & 39 = 101000 & 100111 = 100000`（十进制 32）
|
||||
59. `44 & 43 = 101100 & 101011 = 101000`（十进制 40）
|
||||
60. `72 & 71 = 1001000 & 1000111 = 1000000`（十进制 64）
|
||||
61. 结论：`x & (x-1)` 会把最低位 1 消掉，且更低位保持为 0
|
||||
62. `1 & 0 = 0`
|
||||
63. `2 & 1 = 0`
|
||||
64. `4 & 3 = 0`
|
||||
65. `8 & 7 = 0`
|
||||
66. `3 & 2 = 2`（非 0）
|
||||
67. `6 & 5 = 4`（非 0）
|
||||
68. 结论：`x > 0 && (x & (x - 1)) == 0` 当且仅当 `x` 是 2 的幂
|
||||
69. `64 & 63 = 0`，所以是 2 的幂
|
||||
70. `72 & 71 = 64`，非 0，所以不是 2 的幂
|
||||
71. lowbit 是 `00001000`（8），最低位 1 在第 3 位
|
||||
72. lowbit 是 `00001000`（8），最低位 1 在第 3 位
|
||||
73. lowbit 是 `10000000`（128），最低位 1 在第 7 位
|
||||
74. `90 -> 88 -> 80 -> 64 -> 0`，共 4 步，所以有 4 个 1
|
||||
75. 可用 `(n & 3) == 0`，对应二进制末两位为 `00`

## 一、这节课到底学什么？
|

很多同学觉得流程图难，不是因为图形多，而是因为总会犯下面几种错：
|
||||
|
||||
- 只盯着框看，不顺着箭头走。

||||
- 只看条件，不看两条分支分别去哪。
|
||||
- 看到回头箭头，没有意识到这是一段循环。
|
||||
- 自己画图时，漏了初始化、漏了结束、漏了更新变量。
|
||||
|
||||
所以这份讲义不走“纯概念说明”路线，而是直接看图、读图、再学怎么手绘。
|
||||
|
||||

|
||||
|
||||
## 二、先看一张图，认识流程图里最常见的 4 种框
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
A([开始]) --> B[/输入一个数 n/]
|
||||
B --> C[把 n 加 1]
|
||||
C --> D{n 是偶数吗？}
|
||||
D -- 是 --> E[/输出 偶数/]
|
||||
D -- 否 --> F[/输出 奇数/]
|
||||
E --> G([结束])
|
||||
F --> G
|
||||
```
|
||||
|
||||
这张图先不用细抠题意，只要认识图形就行：
|
||||
|
||||
- 圆角框：开始、结束。
|
||||
- 平行四边形：输入、输出。
|
||||
- 长方形：处理步骤，也就是“做一件事”。
|
||||
- 菱形：判断，要从这里分路。
|
||||
|
||||
你可以先把流程图想成“做事路线图”：
|
||||
|
||||
- 框，表示现在做什么。
|
||||
- 箭头，表示下一步去哪。
|
||||
|
||||
> 读流程图时，真正重要的不是图画得漂不漂亮，而是你能不能顺着箭头走清楚。
|
||||
|
||||
---
|
||||
|
||||
## 三、示范 1：最基础的单判断流程图
|
||||
|
||||
题目：输入一个整数，判断它是偶数还是奇数。
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A([开始]) --> B[/输入 n/]
|
||||
B --> C{n 能被 2 整除吗？}
|
||||
C -- 是 --> D[/输出 偶数/]
|
||||
C -- 否 --> E[/输出 奇数/]
|
||||
D --> F([结束])
|
||||
E --> F
|
||||
```
|
||||
|
||||
读这张图时，顺序应该这样说：
|
||||
|
||||
1. 从“开始”出发。
|
||||
2. 输入一个整数 n。
|
||||
3. 判断 n 能不能被 2 整除。
|
||||
4. 如果能，就输出“偶数”。
|
||||
5. 如果不能，就输出“奇数”。
|
||||
6. 结束。
|
||||
|
||||
这类图最容易错的地方只有一个：
|
||||
|
||||
> 判断框一定要看两条路，不能只看条件本身。
|
||||
|
||||
也就是说，你看到菱形时，要同时问自己两句：
|
||||
|
||||
- 条件成立，往哪走？
|
||||
- 条件不成立，往哪走？
|
||||
|
||||
---
|
||||
|
||||
## 四、示范 2：看到回头箭头，就要想到“循环”
|
||||
|
||||
题目：输入 n，求 1 到 n 的和。
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A([开始]) --> B[/输入 n/]
|
||||
B --> C[sum = 0, i = 1]
|
||||
C --> D{i 还没超过 n 吗？}
|
||||
D -- 否 --> E[/输出 sum/]
|
||||
E --> F([结束])
|
||||
D -- 是 --> G[sum = sum + i]
|
||||
G --> H[i = i + 1]
|
||||
H --> D
|
||||
```
|
||||
|
||||
这张图里，最关键的是最后那条回头箭头：
|
||||
|
||||
- 它从后面回到了前面的判断框。
|
||||
- 这说明有一段步骤要重复做。
|
||||
- 这就是循环。
|
||||
|
||||
### 拿一组小数据，顺着图走一遍
|
||||
|
||||
设 n = 4。
|
||||
|
||||
| 现在的 i | 做完以后 sum | 接下来去哪？ |
|
||||
|:---:|:---:|:---|
|
||||
| 1 | 1 | i 变成 2，回去继续判断 |
|
||||
| 2 | 3 | i 变成 3，回去继续判断 |
|
||||
| 3 | 6 | i 变成 4，回去继续判断 |
|
||||
| 4 | 10 | i 变成 5，回去继续判断 |
|
||||
| 5 | 不再累加 | 因为 5 已经超过 4，所以输出 10 |
|
||||
|
||||
这就是读流程图最稳的方法：
|
||||
|
||||
> 如果看图有点晕，就拿一组很小的数据，自己沿着箭头走一遍。
|
||||
|
||||
---
|
||||
|
||||
## 五、示范 3：有些流程会“提前停止”
|
||||
|
||||
题目：从 1 开始往上加，如果和第一次超过 20，就立刻输出并结束。
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A([开始]) --> B[/输入 n/]
|
||||
B --> C[sum = 0, i = 1]
|
||||
C --> D{i 还没超过 n 吗？}
|
||||
D -- 否 --> E[/输出 sum/]
|
||||
E --> F([结束])
|
||||
D -- 是 --> G[sum = sum + i]
|
||||
G --> H{sum 已经大于 20 吗？}
|
||||
H -- 是 --> E
|
||||
H -- 否 --> I[i = i + 1]
|
||||
I --> D
|
||||
```
|
||||
|
||||
这张图比上一张多了一个判断框。
|
||||
|
||||
它告诉你：
|
||||
|
||||
- 有时候流程不一定走到最下面才结束。
|
||||
- 只要中途满足条件，就可以直接输出并结束。
|
||||
|
||||
### 为什么这类图容易读错？
|
||||
|
||||
因为很多同学会下意识地认为：
|
||||
|
||||
“图上有的步骤，都会执行。”
|
||||
|
||||
其实不是。
|
||||
|
||||
真正正确的想法是：
|
||||
|
||||
> 只有你顺着箭头真的能走到那一步，那一步才会执行。
|
||||
|
||||
比如 n = 10：
|
||||
|
||||
- 1 + 2 + 3 + 4 + 5 = 15。
|
||||
- 再加 6，sum 变成 21。
|
||||
- 这时已经大于 20，所以直接结束。
|
||||
- 后面的 7、8、9、10 根本不会再处理。
|
||||
|
||||
---
|
||||
|
||||
## 六、示范 4：双重循环最容易把人绕晕
|
||||
|
||||
题目：老师给你一张 3 行 4 列的表，从左到右、从上到下寻找第一个 0，找到就立刻输出它的位置。
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A([开始]) --> B[row = 1]
|
||||
B --> C{row 还在第 1 到第 3 行吗？}
|
||||
C -- 否 --> D[/输出 没找到/]
|
||||
D --> E([结束])
|
||||
C -- 是 --> F[col = 1]
|
||||
F --> G{col 还在第 1 到第 4 列吗？}
|
||||
G -- 否 --> H[row = row + 1]
|
||||
H --> C
|
||||
G -- 是 --> I[/读当前位置的数 x/]
|
||||
I --> J{x 是 0 吗？}
|
||||
J -- 是 --> K[/输出 row 和 col/]
|
||||
K --> E
|
||||
J -- 否 --> L[col = col + 1]
|
||||
L --> G
|
||||
```
|
||||
|
||||
这一张图里，其实有两层重复：
|
||||
|
||||
- 外层：一行一行看。
|
||||
- 内层：每一行里，一列一列看。
|
||||
|
||||
读双重循环时，一定要问清楚：
|
||||
|
||||
- 现在正在动的是哪一个变量？
|
||||
- 这一条回边，是回到内层判断，还是回到外层判断？
|
||||
- 找到答案以后，是结束一层，还是结束全部？
|
||||
|
||||
### 这题里有两种“结束”意思完全不同
|
||||
|
||||
第一种：一整行看完了。
|
||||
|
||||
- 这不是整张图结束。
|
||||
- 只是 col 走完了。
|
||||
- 所以下一步是 row 加 1，去下一行。
|
||||
|
||||
第二种：已经找到第一个 0。
|
||||
|
||||
- 这不是只结束当前一行。
|
||||
- 而是整个过程直接输出并结束。
|
||||
|
||||
> 双重循环最容易错的地方，不是看不见箭头，而是分不清“结束一层”和“结束全部”。
|
||||
|
||||
---
|
||||
|
||||
## 七、示范 5：分支、循环、提前结束放在同一张图里
|
||||
|
||||
题目：输入 n，求 1 到 n 中所有 3 的倍数之和；如果和第一次超过 100，就立刻停止并输出。
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A([开始]) --> B[/输入 n/]
|
||||
B --> C[sum = 0, i = 1]
|
||||
C --> D{i 还没超过 n 吗？}
|
||||
D -- 否 --> E[/输出 sum/]
|
||||
E --> F([结束])
|
||||
D -- 是 --> G{i 是 3 的倍数吗？}
|
||||
G -- 是 --> H[sum = sum + i]
|
||||
G -- 否 --> I[i = i + 1]
|
||||
H --> J{sum 已经大于 100 吗？}
|
||||
J -- 是 --> E
|
||||
J -- 否 --> I
|
||||
I --> D
|
||||
```
|
||||
|
||||
这张图值得你重点观察 3 个地方：
|
||||
|
||||
1. 外面有一个循环，因为最后会回到“i 还没超过 n 吗”。
|
||||
2. 中间有一个分支，因为要判断 i 是不是 3 的倍数。
|
||||
3. 还有一个提前结束，因为 sum 超过 100 时可以直接停。
|
||||
|
||||
如果你能把这张图读顺，说明你已经不是只会看“最基础单流程”了。
|
||||
|
||||
---
|
||||
|
||||
## 八、自己手绘流程图，应该怎么下笔？
|
||||
|
||||
看到题目以后，不要一上来就急着画框。
|
||||
|
||||
更稳的顺序是下面这 6 步：
|
||||
|
||||
### 第 1 步：先把做法写成人话
|
||||
|
||||
例如：
|
||||
|
||||
1. 输入 n。
|
||||
2. 令 sum = 0，i = 1。
|
||||
3. 如果 i 已经超过 n，就输出 sum。
|
||||
4. 如果 i 是 3 的倍数，就把它加到 sum 里。
|
||||
5. 如果 sum 已经超过 100，就输出 sum。
|
||||
6. 否则 i 加 1，再继续。
|
||||
|
||||
如果这几句话都说不顺，流程图通常也画不顺。
|
||||
|
||||
### 第 2 步：先找变量
|
||||
|
||||
最常见的几类变量是：
|
||||
|
||||
- 输入变量：题目给你的数。
|
||||
- 循环变量：决定“做到第几个”的变量。
|
||||
- 结果变量：最后要输出的量。
|
||||
- 标记变量：比如“是否找到”。
|
||||
|
||||
### 第 3 步：先搭大骨架
|
||||
|
||||
很多流程图，骨架其实都差不多：
|
||||
|
||||
开始 → 输入 → 初始化 → 判断 → 处理 → 更新 → 回到判断 → 输出 → 结束
|
||||
|
||||
先把主干摆出来，再补细节，图就不会乱。
|
||||
|
||||
### 第 4 步：每个判断框都要有两条路
|
||||
|
||||
判断框不能只画一条路。
|
||||
|
||||
你必须写清楚：
|
||||
|
||||
- 是，去哪。
|
||||
- 否，去哪。
|
||||
|
||||
### 第 5 步：循环的回边，通常回到判断框
|
||||
|
||||
很多同学会把箭头直接接回处理中间某一步，这很容易画错。
|
||||
|
||||
更常见、更稳的画法是：
|
||||
|
||||
- 处理完一轮。
|
||||
- 更新变量。
|
||||
- 回到“是否继续”的判断框。
|
||||
|
||||
### 第 6 步：画完以后，用小数据手推
|
||||
|
||||
这一招非常重要。
|
||||
|
||||
你可以拿最小的几组数据来试：
|
||||
|
||||
- n = 1 会怎样？
|
||||
- n = 0 会怎样？
|
||||
- 第一次就满足结束条件会怎样？
|
||||
|
||||
如果你自己都推不顺，说明图还得改。
|
||||
|
||||
---
|
||||
|
||||
## 九、手绘时最容易犯的错误
|
||||
|
||||
下面这些错，课堂上特别常见：
|
||||
|
||||
1. 漏掉开始和结束。
|
||||
2. 忘了初始化变量。
|
||||
3. 判断框只画出一条路。
|
||||
4. 循环变量没有更新，结果图会一直转圈。
|
||||
5. 回边接错位置，没有回到判断框。
|
||||
6. 双重循环里，没有分清是结束一层还是结束全部。
|
||||
7. 一个框里塞太多话，别人读不清楚。
|
||||
8. 箭头方向不清，让人只能靠猜。
|
||||
|
||||
---
|
||||
|
||||
## 十、画完之后，按这张检查单自查
|
||||
|
||||
1. 有没有明确的开始和结束？
|
||||
2. 输入和输出有没有写清楚？
|
||||
3. 初始化有没有漏掉？
|
||||
4. 每个判断框是不是都有两条路？
|
||||
5. 每个循环变量有没有更新？
|
||||
6. 回头箭头是不是回到了合适的位置？
|
||||
7. 如果有提前停止，是不是画清楚了？
|
||||
8. 如果有双重循环，是不是分清了结束一层和结束全部？
|
||||
9. 能不能拿一组小数据，从头走到尾？
|
||||
|
||||
只要这 9 条都能过，这张图一般就比较靠谱了。
|
||||

||||

|
||||
|
||||
## 十一、课堂练习
|
||||
|
||||
下面 3 题，不要求你写代码，先试着手绘流程图：
|
||||
|
||||
### 练习 1
|
||||
|
||||
输入 n，输出 1 到 n 中偶数的个数。
|
||||
|
||||
### 练习 2
|
||||
|
||||
从左到右读一串数，遇到 0 就停止，输出前面所有数的和。
|
||||
|
||||
### 练习 3
|
||||
|
||||
读一个 3 行 4 列的表，找到第一个大于 100 的数，输出它的位置；如果没有找到，就输出“没有”。
|
||||
|
||||
做这 3 题时，请先写“人话步骤”，再画图。
|
||||
|
||||
---
|
||||
|
||||
## 十二、这一节最该记住的几句话
|
||||
|
||||
1. 流程图不是背图形，而是按顺序表达做事步骤。
|
||||
2. 读图时，最重要的是顺着箭头走。
|
||||
3. 看到菱形，就要同时看“是”和“否”两条路。
|
||||
4. 看到回头箭头，通常就要想到循环。
|
||||
5. 不是图上写了什么都会执行，要看箭头能不能真的走到那一步。
|
||||
6. 画图前先把步骤说清楚，画完后再拿小数据手推。
|
||||
|
||||
如果你能做到这 6 条，流程图这一关就算真正入门了。

# 4.1 自定义函数和递归
|
||||
|
||||
---
|
||||
|
||||
## 一、这一节到底学什么？
|
||||
|
||||
这一节不要求你一下子把函数和递归全背下来。
|
||||
|
||||
你只要先抓住下面 4 件事就够了：
|
||||
|
||||
1. 知道什么时候要把一段代码单独写成函数。
|
||||
2. 会写最基础的自定义函数定义。
|
||||
3. 能顺着流程图读懂“函数被调用时发生了什么”。
|
||||
4. 初步看懂递归是怎样一层一层调用、再一层一层返回的。
|
||||
|
||||
整份讲义里，我们会尽量用能直接代数字的小例子来讲，不走太空的定义路线。
|
||||
|
||||
---
|
||||
|
||||
## 二、为什么要写函数，而不是一直往下写？
|
||||
|
||||
先看一种很常见的情况：
|
||||
|
||||
- 你要多次做同一件事。
|
||||
- 这件事本身可以起一个名字。
|
||||
- 把它拆出去以后，主程序会更清楚。
|
||||
|
||||
比如你要处理一张全班成绩表。
|
||||
|
||||
题目要求你完成下面这些事：
|
||||
|
||||
- 读入每个同学的语文、数学、英语成绩。
|
||||
- 计算每个同学的总分。
|
||||
- 计算每个同学的平均分。
|
||||
- 判断每个同学是否及格。
|
||||
- 最后输出全班总分前 3 名。
|
||||
|
||||
如果你完全不用函数，程序很可能会变成这样：
|
||||
|
||||
- 主程序里一大段是在算总分。
|
||||
- 后面又来一大段是在算平均分。
|
||||
- 再后面又来一大段是在判断是否及格。
|
||||
- 如果输出前 3 名时还要反复比较、交换，主程序会更长。
|
||||
|
||||
这样写会有几个明显问题：
|
||||
|
||||
- 主程序会越来越像一团挤在一起的步骤，不容易看出主线。
|
||||
- 同样的计算规则如果写了好几次，改错时很容易漏掉某一处。
|
||||
- 过几天再回头看，你很难一下分清哪一段在“算分数”，哪一段在“判及格”，哪一段在“排前 3 名”。
|
||||
|
||||
这时如果把任务拆开：
|
||||
|
||||
- 写一个函数专门求总分。
|
||||
- 写一个函数专门求平均分。
|
||||
- 写一个函数专门判断是否及格。
|
||||
|
||||
主程序就会清楚很多。
|
||||
|
||||
所以你可以把“一段完成固定任务的代码”单独拿出来，给它起个名字，这就是函数。
|
||||
|
||||
你可以先把函数理解成：
|
||||
|
||||
> 一个能完成某项任务的小工具。
|
||||
|
||||
主程序需要它时，就“叫它来做事”。
|
||||
|
||||
---
|
||||
|
||||
## 三、最基础的函数长什么样？
|
||||
|
||||
最常见的写法是：
|
||||
|
||||
```cpp
|
||||
返回值类型 函数名(参数列表)
|
||||
{
|
||||
函数体
|
||||
}
|
||||
```
|
||||
|
||||
先不用被名字吓住，直接把这 3 部分拆开看：
|
||||
|
||||
先配一个很具体的例子：
|
||||
|
||||
```cpp
|
||||
int total_score(int chinese, int math, int english)
|
||||
{
|
||||
int sum = chinese + math + english;
|
||||
return sum;
|
||||
}
|
||||
```
|
||||
|
||||
这个函数做的事非常明确：
|
||||
|
||||
- 给它语文、数学、英语 3 个分数。
|
||||
- 它帮你算出总分。
|
||||
- 最后把总分交回来。
|
||||
|
||||
### 1. 返回值类型
|
||||
|
||||
表示这个函数做完以后，要交回什么类型的结果。
|
||||
|
||||
例如：
|
||||
|
||||
- `int`：交回一个整数。
|
||||
- `double`：交回一个小数。
|
||||
- `bool`：交回真或假。
|
||||
- `void`：不交回结果。
|
||||
|
||||
在刚才那个例子里：
|
||||
|
||||
- `total_score` 最后交回来的是总分。
|
||||
- 总分通常是整数。
|
||||
- 所以这里写 `int`。
|
||||
|
||||
### 2. 函数名
|
||||
|
||||
就是这个函数的名字。
|
||||
|
||||
名字最好能让人一眼看出用途，比如：
|
||||
|
||||
- `add`
|
||||
- `is_even`
|
||||
- `sum_to_n`
|
||||
|
||||
如果是给六年级同学自己写，名字能看懂比“高大上”更重要。
|
||||
|
||||
像：
|
||||
|
||||
- `total_score`
|
||||
- `print_line`
|
||||
- `sum_to_n`
|
||||
|
||||
都比随便写成 `f1`、`abc` 更容易读。
|
||||
|
||||
### 3. 参数列表
|
||||
|
||||
表示调用这个函数时，要给它哪些数据。
|
||||
|
||||
例如前面的成绩函数：
|
||||
|
||||
```cpp
|
||||
int total_score(int chinese, int math, int english)
|
||||
```
|
||||
|
||||
意思就是：
|
||||
|
||||
- 这个函数叫 `total_score`。
|
||||
- 它需要 3 个整数，分别叫 `chinese`、`math`、`english`。
|
||||
- 它最后会返回一个整数，也就是总分。
|
||||
|
||||
如果把真实数字代进去，比如：
|
||||
|
||||
- 语文 92 分
|
||||
- 数学 87 分
|
||||
- 英语 95 分
|
||||
|
||||
那么这个函数的任务就是算：
|
||||
|
||||
$$
|
||||
92 + 87 + 95 = 274
|
||||
$$
|
||||

## 四、函数的意义：同一件事，只写一次
|
||||
|
||||
先看一个场景。
|
||||
|
||||
你需要算 3 个同学各自的总分：
|
||||
|
||||
- 小明：语文 92，数学 87，英语 95
|
||||
- 小红：语文 78，数学 85，英语 80
|
||||
- 小刚：语文 88，数学 90，英语 76
|
||||
|
||||
如果不用函数，主程序会这样写：
|
||||
|
||||
```cpp
|
||||
int sum1 = 92 + 87 + 95; // 小明的总分
|
||||
int sum2 = 78 + 85 + 80; // 小红的总分
|
||||
int sum3 = 88 + 90 + 76; // 小刚的总分
|
||||
```
|
||||
|
||||
如果有 30 个同学，就要写 30 行。
|
||||
|
||||
而且"加 3 个数"这件事，每次都要重复写一遍。
|
||||
|
||||
这时可以定义一个函数，把"怎么加"这件事单独写好：
|
||||
|
||||
```cpp
|
||||
int total_score(int chinese, int math, int english)
|
||||
{
|
||||
int sum = chinese + math + english;
|
||||
return sum;
|
||||
}
|
||||
```
|
||||
|
||||
然后在主函数里，每个同学用一行搞定：
|
||||
|
||||
```cpp
|
||||
int sum1 = total_score(92, 87, 95); // 小明的总分，得到 274
|
||||
int sum2 = total_score(78, 85, 80); // 小红的总分，得到 243
|
||||
int sum3 = total_score(88, 90, 76); // 小刚的总分，得到 254
|
||||
```
|
||||
|
||||
"怎么算总分"只定义了一次，却被叫了 3 次。
|
||||
|
||||
这就是函数最核心的意义：
|
||||
|
||||
> 把一件事的做法写一次，想用多少次就叫多少次。
|
||||
|
||||
### 用流程图看清楚"调用"发生了什么
|
||||
|
||||
下面这张图展示的是：主函数叫了 `total_score` 两次，每次都跳出去执行函数，结束后再回来继续。
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
subgraph M["主函数 main"]
|
||||
A([开始]) --> B["准备小明的分数\n92, 87, 95"]
|
||||
B --> C["调用①"]
|
||||
C --> H["sum1 = 274"]
|
||||
H --> I["准备小红的分数\n78, 85, 80"]
|
||||
I --> J["调用②"]
|
||||
J --> K["sum2 = 243"]
|
||||
K --> L[/输出 sum1, sum2/]
|
||||
L --> Z([结束])
|
||||
end
|
||||
|
||||
subgraph F["函数 total_score（只写了一次）"]
|
||||
D["收到参数"] --> E["sum = chinese + math + english"]
|
||||
E --> G["return sum"]
|
||||
end
|
||||
|
||||
C -- "传入 92,87,95" --> D
|
||||
G -- "返回 274" --> H
|
||||
J -- "传入 78,85,80" --> D
|
||||
G -- "返回 243" --> K
|
||||
```
|
||||
|
||||
注意流程图里的关键点：
|
||||
|
||||
- 每次调用，都会"跳进"函数那个框里执行。
|
||||
- 函数执行完以后，再"跳回"主函数继续往下走。
|
||||
- 函数本身的代码只写了一份，但被用了两次。
|
||||
|
||||
---
|
||||
|
||||
## 五、值传递到底是什么意思？
|
||||
|
||||
这是这一节最重要的基础概念。
|
||||
|
||||
看下面这组代码：
|
||||
|
||||
```cpp
|
||||
int add_bonus(int score)
|
||||
{
|
||||
score = score + 10;
|
||||
return score;
|
||||
}
|
||||
|
||||
int main()
|
||||
{
|
||||
int math = 87;
|
||||
int new_score = add_bonus(math);
|
||||
}
|
||||
```
|
||||
|
||||
很多同学第一眼会担心：
|
||||
|
||||
- 函数里把 `score` 改了，那外面的 `math` 会不会也变？
|
||||
|
||||
这一节里，答案是：
|
||||
|
||||
> 不会。
|
||||
|
||||
因为我们现在只讲值传递。
|
||||
|
||||
调用 `add(x, y)` 时，发生的是：
|
||||
|
||||
调用 `add_bonus(math)` 时，发生的是：
|
||||
|
||||
- 把 `math` 当前的值 87 交给函数里的 `score`。
|
||||
- 函数内部拿到的是一份新的 87。
|
||||
|
||||
所以：
|
||||
|
||||
- `score` 和 `math` 不是同一个变量。
|
||||
|
||||
你可以把它理解成：
|
||||
|
||||
- 主程序把这个分数抄了一份给函数。
|
||||
- 函数只是在自己的小房间里处理这份副本。
|
||||
- 函数结束以后，主程序里的原变量不受影响。
|
||||
|
||||
### 用一组数据走一遍
|
||||
|
||||
当 `math = 87` 时：
|
||||
|
||||
- 进入函数时，`score = 87`。
|
||||
- 执行 `score = score + 10` 后，`score = 97`。
|
||||
- 返回 97。
|
||||
|
||||
但主函数里的：
|
||||
|
||||
- `math` 还是 87。
|
||||
|
||||
最后会变成：
|
||||
|
||||
- `math = 87`
|
||||
- `new_score = 97`
|
||||
|
||||
也就是说：
|
||||
|
||||
- 原来的分数没被直接改掉。
|
||||
- 只是函数帮你算出了“加 10 分以后”的新结果。
|
||||
|
||||
这一点一定要和“函数内部变量的变化”区分开。
|
||||
|
||||
---
|
||||
|
||||
## 六、函数调用时，流程图应该怎么看？
|
||||
|
||||
先看一个非常基础的例子：主函数调用 `total_score(chinese, math, english)`。
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A([开始]) --> B["chinese = 92, math = 87, english = 95"]
|
||||
B --> C["调用 total_score(chinese, math, english)"]
|
||||
C --> D["把 92, 87, 95 交给函数里的 3 个参数"]
|
||||
D --> E["sum = 92 + 87 + 95"]
|
||||
E --> F["return 274"]
|
||||
F --> G["ans 得到返回值"]
|
||||
G --> H[/输出 ans/]
|
||||
H --> I([结束])
|
||||
```
|
||||
|
||||
这张图里最重要的是中间 3 步：
|
||||
|
||||
1. 调用函数。
|
||||
2. 把实参的值交给形参。
|
||||
3. 函数算完以后，把结果返回。
|
||||
|
||||
### 这里有两个名字要分清
|
||||
|
||||
- 实参：调用时真正传进去的东西，比如 `chinese`、`math`、`english`。
|
||||
- 形参：函数定义里接收数据的变量，比如 `chinese`、`math`、`english` 这 3 个参数名。
|
||||
|
||||
你不需要死背这两个词，但一定要明白它们不是同一个层面的名字。
|
||||
|
||||
---
|
||||
|
||||
## 七、把“主函数”和“被调用函数”分开看，会更清楚
|
||||
|
||||
如果你总觉得函数调用时会乱，可以把它想成两块：
|
||||
|
||||
- 主函数负责“发任务”。
|
||||
- 被调用函数负责“做任务”。
|
||||
|
||||
看这张图：
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
subgraph M[主函数 main]
|
||||
A[准备 3 个分数] --> B["调用 total_score(...)"]
|
||||
C[接住返回值 ans] --> D[/输出 ans/]
|
||||
end
|
||||
|
||||
subgraph F[函数 total_score]
|
||||
E[收到 3 个分数] --> F1[把 3 个分数加起来]
|
||||
F1 --> G[返回总分]
|
||||
end
|
||||
|
||||
B --> E
|
||||
G --> C
|
||||
```
|
||||
|
||||
这样看会更像真实过程：
|
||||
|
||||
- 主函数把任务送进去。
|
||||
- `add` 做完再把结果送回来。
|
||||
|
||||
> 函数不是“贴在原地执行的一行代码”，而是一次完整的小过程。
|
||||
|
||||
---
|
||||
|
||||
## 八、什么时候用 `void` 函数？
|
||||
|
||||
不是所有函数都一定要“返回一个结果”。
|
||||
|
||||
比如下面这个函数：
|
||||
|
||||
```cpp
|
||||
void print_line()
|
||||
{
|
||||
cout << "----------" << endl;
|
||||
}
|
||||
```
|
||||
|
||||
它的任务只是输出一行分隔线。
|
||||
|
||||
所以：
|
||||
|
||||
- 它做事。
|
||||
- 但它不需要交回一个数。
|
||||
|
||||
这时就可以写成 `void`。
|
||||
|
||||
你可以把它理解成：
|
||||
|
||||
> `void` 函数负责“做动作”，不负责“交答案”。
|
||||
|
||||
如果把它放进主函数里：
|
||||
|
||||
```cpp
|
||||
print_line();
|
||||
cout << "欢迎来到成绩统计程序" << endl;
|
||||
print_line();
|
||||
```
|
||||
|
||||
它的作用就很直观：
|
||||
|
||||
- 不是算分数。
|
||||
- 不是算答案。
|
||||
- 只是帮你把输出排得更整齐。
|
||||
|
||||
---
|
||||
|
||||
## 九、递归到底是什么？
|
||||
|
||||
递归只有一句核心定义：
|
||||
|
||||
> 函数在自己的函数体里调用自己。
|
||||
|
||||
第一次看到这句话，很多同学会立刻觉得：
|
||||
|
||||
- “那不是会一直套下去吗？”
|
||||
|
||||
所以学递归时，最关键的不是先背代码，而是先抓住两件事：
|
||||
|
||||
1. 一定要有“停止条件”。
|
||||
2. 每次递归都要朝着停止条件靠近。
|
||||
|
||||
如果没有停止条件，函数就会没完没了地继续调用。
|
||||
|
||||
如果虽然有停止条件，但每次都没有更接近它，那也一样会出问题。
|
||||
|
||||
---
|
||||
|
||||
## 十、先看一个最简单的递归函数
|
||||
|
||||
题目：求 1 到 n 的和。
|
||||
|
||||
我们把它写成：
|
||||
|
||||
```cpp
|
||||
int sum_to_n(int n)
|
||||
{
|
||||
if (n == 1)
|
||||
{
|
||||
return 1;
|
||||
}
|
||||
return n + sum_to_n(n - 1);
|
||||
}
|
||||
```
|
||||
|
||||
这段代码可以读成：
|
||||
|
||||
- 如果 `n == 1`，那答案就是 1，直接返回。
|
||||
- 如果 `n > 1`，那么
|
||||
`1 + 2 + ... + n`
|
||||
就等于
|
||||
`n + (1 + 2 + ... + (n - 1))`。
|
||||
|
||||
所以它把原问题拆成了一个更小的问题：
|
||||
|
||||
- `sum_to_n(n)`
|
||||
- 变成
|
||||
- `n + sum_to_n(n - 1)`
|
||||
|
||||
这就是递归最常见的思路：
|
||||
|
||||
> 大问题，拆成一个同类但更小的问题。
|
||||
|
||||
你可以把它想成一堆叠起来的小卡片：
|
||||
|
||||
- 要算前 4 张卡片上的数字和。
|
||||
- 可以先拿最上面这一张 4。
|
||||
- 剩下的问题就变成“前 3 张卡片的和是多少”。
|
||||
|
||||
这样就从“4 张”慢慢变成“3 张”“2 张”“1 张”。
|
||||
|
||||
---
|
||||
|
||||
## 十一、递归流程图怎么画？
|
||||
|
||||
先看结构图：
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A(["进入 sum_to_n(n)"]) --> B{n == 1 吗？}
|
||||
B -- 是 --> C[return 1]
|
||||
B -- 否 --> D["计算 sum_to_n(n - 1)"]
|
||||
D --> E[返回 n + 子问题结果]
|
||||
C --> F([结束本层调用])
|
||||
E --> F
|
||||
```
|
||||
|
||||
这张图里，你必须抓住两条路：
|
||||
|
||||
- 一条是“直接结束”的路，也就是停止条件。
|
||||
- 一条是“继续缩小问题”的路，也就是递归调用。
|
||||
|
||||
没有前者，停不下来。
|
||||
|
||||
没有后者，就不是递归。
|
||||
|
||||
---
|
||||
|
||||
## 十二、拿 `sum_to_n(4)` 手推一遍，最重要
|
||||
|
||||
只看代码，很多同学会晕。
|
||||
|
||||
这时最稳的方法就是：
|
||||
|
||||
> 拿一个很小的数，自己顺着调用过程走一遍。
|
||||
|
||||
### 第一步：往下调用
|
||||
|
||||
```text
|
||||
sum_to_n(4)
|
||||
= 4 + sum_to_n(3)
|
||||
|
||||
sum_to_n(3)
|
||||
= 3 + sum_to_n(2)
|
||||
|
||||
sum_to_n(2)
|
||||
= 2 + sum_to_n(1)
|
||||
|
||||
sum_to_n(1)
|
||||
= 1
|
||||
```
|
||||
|
||||
看到这里，终于碰到了停止条件。
|
||||
|
||||
### 第二步：往回返回
|
||||
|
||||
```text
|
||||
sum_to_n(1) = 1
|
||||
sum_to_n(2) = 2 + 1 = 3
|
||||
sum_to_n(3) = 3 + 3 = 6
|
||||
sum_to_n(4) = 4 + 6 = 10
|
||||
```
|
||||
|
||||
所以最后答案是 10。
|
||||
|
||||
### 再用表格看一遍
|
||||
|
||||
| 这一层在算谁？ | 它先等谁？ | 等到以后自己返回多少？ |
|
||||
|:---:|:---:|:---:|
|
||||
| `sum_to_n(4)` | 等 `sum_to_n(3)` | `4 + 6 = 10` |
|
||||
| `sum_to_n(3)` | 等 `sum_to_n(2)` | `3 + 3 = 6` |
|
||||
| `sum_to_n(2)` | 等 `sum_to_n(1)` | `2 + 1 = 3` |
|
||||
| `sum_to_n(1)` | 不用再等 | `1` |
|
||||
|
||||
这张表很重要，因为它把“先等谁、再返回多少”写得很清楚。
|
||||
|
||||
---
|
||||
|
||||
## 十三、递归最容易绕晕的地方，不在“往下”，而在“往回”
|
||||
|
||||
很多同学能接受：
|
||||
|
||||
- `sum_to_n(4)` 去叫 `sum_to_n(3)`。
|
||||
- `sum_to_n(3)` 再去叫 `sum_to_n(2)`。
|
||||
|
||||
但一到返回时就乱了。
|
||||
|
||||
原因通常是没有意识到：
|
||||
|
||||
> 每一层函数调用，都在等自己的“下一层”先把结果交回来。
|
||||
|
||||
也就是说：
|
||||
|
||||
- `sum_to_n(4)` 不能立刻算完。
|
||||
- 它必须先等 `sum_to_n(3)` 返回。
|
||||
- `sum_to_n(3)` 又得先等 `sum_to_n(2)`。
|
||||
- 一直等到最小那层先返回。
|
||||
|
||||
所以递归过程常常像两段：
|
||||
|
||||
1. 一层一层往下走。
|
||||
2. 一层一层往上交答案。
|
||||
|
||||
---
|
||||
|
||||
## 十四、把递归看成“排队等结果”，会更好懂
|
||||
|
||||
再看一张图：
|
||||
|
||||
```mermaid
|
||||
flowchart TD
|
||||
A["sum_to_n(4)"] --> B["等待 sum_to_n(3)"]
|
||||
B --> C["等待 sum_to_n(2)"]
|
||||
C --> D["等待 sum_to_n(1)"]
|
||||
D --> E["sum_to_n(1) 返回 1"]
|
||||
E --> F["sum_to_n(2) 返回 3"]
|
||||
F --> G["sum_to_n(3) 返回 6"]
|
||||
G --> H["sum_to_n(4) 返回 10"]
|
||||
```
|
||||
|
||||
这张图要表达的重点不是代码细节，而是“顺序”：
|
||||
|
||||
- 先不断往下等。
|
||||
- 再从最底层开始往回交结果。
|
||||
|
||||
你甚至可以把它读成下面这几句话：
|
||||
|
||||
- 4 这一层先别急，先去问 3。
|
||||
- 3 这一层也先别急，先去问 2。
|
||||
- 2 这一层再去问 1。
|
||||
- 1 最简单，直接回答：我是 1。
|
||||
- 然后答案一层一层往回传。
|
||||
|
||||
如果你能把这张图说顺，说明你已经抓住递归最核心的运行过程了。
|
||||
|
||||
---
|
||||
|
||||
## 十五、值传递放到递归里，还是一样的
|
||||
|
||||
递归虽然看起来更复杂，但参数传递规则没有变。
|
||||
|
||||
例如：
|
||||
|
||||
- 调用 `sum_to_n(4)` 时，这一层的 `n` 是 4。
|
||||
- 它再调用 `sum_to_n(3)` 时，下一层会有一个新的 `n`，值是 3。
|
||||
- 再下一层调用 `sum_to_n(2)` 时，又会有一个新的 `n`，值是 2。
|
||||
|
||||
所以：
|
||||
|
||||
- 每一层都有自己的 `n`。
|
||||
- 它们不是同一个变量。
|
||||
- 只是名字都叫 `n` 而已。
|
||||
|
||||
这也是值传递的一部分：
|
||||
|
||||
> 每次调用，都会得到这一层自己的那份参数值。
|
||||
|
||||
---
|
||||
|
||||
## 十六、写递归时，先问自己这两个问题
|
||||
|
||||
在真正动手写递归前，最好先问：
|
||||
|
||||
### 1. 什么时候停？
|
||||
|
||||
也就是停止条件是什么。
|
||||
|
||||
例如：
|
||||
|
||||
- `n == 1` 时停。
|
||||
- `n == 0` 时停。
|
||||
|
||||
### 2. 怎么把问题变小？
|
||||
|
||||
也就是下一次调用时，参数怎么变化。
|
||||
|
||||
例如：
|
||||
|
||||
- `n - 1`
|
||||
- `n / 2`
|
||||
|
||||
如果这两个问题答不出来，递归代码通常也写不稳。
|
||||
|
||||
---
|
||||
|
||||
## 十七、最常见的错误
|
||||
|
||||
下面这些错非常常见：
|
||||
|
||||
1. 写了递归调用，却没有停止条件。
|
||||
2. 虽然写了停止条件，但永远到不了它。
|
||||
3. 只会往下套，不会分析怎么往回返回。
|
||||
4. 把“这一层的参数”和“下一层的参数”混成同一个东西。
|
||||
5. 以为函数里的参数改了，主函数里的变量也会跟着改。
|
||||
|
||||
第 5 条在这一节里尤其要避免，因为本节只讲值传递。
|
||||
|
||||
---
|
||||
|
||||
## 十八、这一节最该记住的几句话
|
||||
|
||||
1. 函数就是把一段固定任务单独拿出来，起个名字反复用。
|
||||
2. 最基础的函数定义要看清：返回值类型、函数名、参数列表。
|
||||
3. 调用函数时，主程序是“发任务”，函数是“做任务”。
|
||||
4. 本节只讲值传递，所以函数拿到的是一份新的值，不会直接改掉外面的原变量。
|
||||
5. 递归就是函数调用自己。
|
||||
6. 递归必须同时具备两件事：停止条件、缩小问题。
|
||||
7. 读递归最稳的方法，是拿小数据手推，先看往下调用，再看往回返回。
|

## 十九、课堂练习
|
||||
|
||||
### 练习 1
|
||||
|
||||
写一个函数 `int square(int x)`，返回 `x * x`。
|
||||
|
||||
要求：
|
||||
|
||||
- 先说清楚参数是什么。
|
||||
- 再说清楚返回值是什么。
|
||||
|
||||
### 练习 2
|
||||
|
||||
主函数中有 `a = 6`，调用 `triple(a)`，其中函数内部把形参乘以 3。
|
||||
|
||||
问题：
|
||||
|
||||
- 函数返回什么？
|
||||
- 主函数里的 `a` 会不会变？
|
||||
|
||||
### 练习 3
|
||||
|
||||
把 `sum_to_n(5)` 的递归调用过程手写出来，写清楚：
|
||||
|
||||
- 往下调用到了哪一层。
|
||||
- 往回返回时每层结果是多少。
|
||||
|
||||
如果这 3 题都能自己说顺，这一节就算真正入门了。

GNU GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom to
|
||||
share and change all versions of a program--to make sure it remains free
|
||||
software for all its users. We, the Free Software Foundation, use the
|
||||
GNU General Public License for most of our software; it applies also to
|
||||
any other work released this way by its authors. You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
them if you wish), that you receive source code or can get it if you
|
||||
want it, that you can change the software or use pieces of it in new
|
||||
free programs, and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you have
|
||||
certain responsibilities if you distribute copies of the software, or if
|
||||
you modify it: responsibilities to respect the freedom of others.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. You must make sure that they, too, receive
|
||||
or can get the source code. And you must show them these terms so they
|
||||
know their rights.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the manufacturer
|
||||
can do so. This is fundamentally incompatible with the aim of
|
||||
protecting users' freedom to change the software. The systematic
|
||||
pattern of such abuse occurs in the area of products for individuals to
|
||||
use, which is precisely where it is most unacceptable. Therefore, we
|
||||
have designed this version of the GPL to prohibit the practice for those
|
||||
products. If such problems arise substantially in other domains, we
|
||||
stand ready to extend this provision to those domains in future versions
|
||||
of the GPL, as needed to protect the freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish to
|
||||
avoid the special danger that patents applied to a free program could
|
||||
make it effectively proprietary. To prevent this, the GPL assures that
|
||||
patents cannot be used to render the program non-free.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.

||||

||||

"This License" refers to version 3 of the GNU General Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Use with the GNU Affero General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of
|
||||
the GNU General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Program specifies that a certain numbered version of the GNU General
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU General Public License, you may choose any version ever published
|
||||
by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future
|
||||
versions of the GNU General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
||||
SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
