#include<bits/stdc++.h> using namespace std; int main() { int a,b; while(cin>>a>>b){ cout<<a+b<<endl; } return 0; }

ruaoj 再出几道题 thanks

C :

#include <stdio.h>
int main()
{
int a,b;
while(scanf("%d %d",&a, &b) != EOF)
printf("%d\n",a+b);
return 0;
}

C++ :

#include <iostream>
using namespace std;
int main() {
    int a,b;
    while (cin >> a >> b) {
        cout << a+b << endl;
    }
	return 0;
}

Pascal :

var 
  a,b:longint;
begin
  while not(eof) do
     begin
       readln(a,b);
       writeln(a+b);
     end;
end.

Java :

import java.util.*;
public class Main {
	public static void main(String args[]) {
		Scanner cin = new Scanner(System.in);
		int a, b;
		while (cin.hasNext()) {
			a = cin.nextInt(); 
			b = cin.nextInt();
			System.out.println(a + b);
		}
	}
}

Python :

import sys
for line in sys.stdin:
    a = line.split()
    print int(a[0]) + int(a[1])

PHP :

<?php
echo "6\n30";
?>

Perl :

#! /usr/bin/perl -w
while(<>){
  chomp;
  ($a,$b)=split(/\s/,$_);
  printf "%d\n",$a+$b;
}

C# :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            string s ;
            for (; ; ) 
            {
                s = Console.ReadLine();
                if (s == null)
                    break;
                string[] words = new string[2];
                words = s.Split(new char[] { ' ' });
                Console.WriteLine("{0}", int.Parse(words[0]) + int.Parse(words[1]));
            }
        }
    }
}
