<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 &quot;Wrong Answer&quot;. User programs are not allowed to open and read from/write to files. You will get a &quot;Runtime Error&quot; or a &quot;Wrong Answer&quot; if you try to do so. Here is a sample solution for problem 1000 using C++/G++:</p>
<pre>
#include &lt;iostream&gt;
using namespace std;
int  main()
{
    int a,b;
    cin &gt;&gt; a &gt;&gt; b;
    cout &lt;&lt; a+b &lt;&lt; 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 &lt;stdio.h&gt;

int main()
{
    int a,b;
    scanf(&quot;%d %d&quot;,&amp;a, &amp;b);
    printf(&quot;%d\n&quot;,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>
import java.io.*;
import java.util.*;
public class Main
{
            public static void main(String args[]) throws Exception
            {
                    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>
import java.io.*;
import java.util.*;

public class Main
{
    public static void main (String args[]) throws Exception
    {
        BufferedReader stdin = 
            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);
    }
}</pre>]]></hint>
