标准代码（仅供参考）：

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;

}

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);

}

}
