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,c;
	cin>>a>>b;
	c=a+b;
	cout<<c;
	return 1;
}

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);
		}
	}
}

Ruby :

a=gets.chomp

b="0"

a.each_line(" "){

|d|

b=b+"+"+d

}

puts eval(b)

Python :

l = raw_input()
a, b= l.split()
print int(a) + int(b)

Perl :

while (<>) {($a, $b) = split; print $a+$b,"\n" }

C# :

using System;
 
public class Sum
{
    public static void Main()
    {
        for(int k = 0; k < 1;k++){
             string[] tokens = Console.ReadLine().Split(' ');
         Console.WriteLine(int.Parse(tokens[0]) + int.Parse(tokens[1]));
    }
    }
}

FreeBasic :

dim a as integer
dim b as integer
input "",a,b
print str(a+b)
