<hint><![CDATA[<p>Q: Where are the input and the output? A: Your program shall always <font color="#ff0000">read input from stdin (Standard Input) and write output to stdout (Standard Output)</font>. For example, you can use 'scanf' in C or 'cin' in C++ to read from stdin, and use 'printf' in C or 'cout' in C++ to write to stdout. You <font color="#ff0000">shall not output any extra data</font> to standard output other than that required by the problem, otherwise you will get a "Wrong Answer". User programs are not allowed to open and read from/write to files. You will get a "Runtime Error" or a "Wrong Answer" if you try to do so. Here is a sample solution for problem 1000 using C++/G++:</p>
|
||||
<pre>
|
||||
#include <iostream>
|
||||
using namespace std;
|
||||
int main()
|
||||
{
|
||||
int a,b;
|
||||
cin >> a >> b;
|
||||
cout << a+b << endl;
|
||||
return 0;
|
||||
}</pre>
|
||||
<p>It's important that the return type of main() must be int when you use G++/GCC,or you may get compile error. Here is a sample solution for problem 1000 using C/GCC:</p>
|
||||
<pre>
|
||||
#include <stdio.h>
|
||||
|
||||
int main()
|
||||
{
|
||||
int a,b;
|
||||
scanf("%d %d",&a, &b);
|
||||
printf("%d\n",a+b);
|
||||
return 0;
|
||||
}</pre>
|
||||
<p>Here is a sample solution for problem 1000 using PASCAL:</p>
|
||||
<pre>
|
||||
program p1000(Input,Output);
|
||||
var
|
||||
a,b:Integer;
|
||||
begin
|
||||
Readln(a,b);
|
||||
Writeln(a+b);
|
||||
end.</pre>
|
||||
<p>Here is a sample solution for problem 1000 using JAVA: Now java compiler is jdk 1.5, next is program for 1000</p>
|
||||
<pre>

|

{
|
||||
Scanner cin=new Scanner(System.in);
|
||||
int a=cin.nextInt();
|
||||
int b=cin.nextInt();
|
||||
System.out.println(a+b);
|
||||
}
|
||||
}</pre>
|
||||
<p>Old program for jdk 1.4</p>
|
||||
<pre>
|

new BufferedReader(
|

new InputStreamReader(System.in));
|
||||
|

String line = stdin.readLine();
|
||||
StringTokenizer st = new StringTokenizer(line);
|
||||
int a = Integer.parseInt(st.nextToken());
|
||||
int b = Integer.parseInt(st.nextToken());
|

System.out.println(a+b);
