这篇博客介绍了经典的A+B问题，要求根据输入的两个整数a和b计算它们的和。输入包含多个测试用例，每个用例占一行，包含a和b。输出要求对每个测试用例在新行上打印它们的和。样例输入和输出并未提供。

A+B Problem
描述
Given two integers a and b, calculate their sum a + b.
输入
The input contains several test cases. Each contains a line of two integers, a and b.
输出
For each test case output a+b on a seperate line.
样例输入

语言 样例程序
C #include <stdio.h>
	
int main(void) {
    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(void) {
    int a, b;
    while(cin >> a >> b) {
    	cout << a + b << endl;
    }
    return 0;
}
Java import java.util.Scanner;
	
public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        while(in.hasNext()) {
        	int a = in.nextInt();
        	int b = in.nextInt();
        	System.out.println(a + b);
        }
    }
}
C# using System;

public class AplusB
{
    private static void Main()
    {
        string line;
        while((line = Console.ReadLine()) != null)
        {
            string[] tokens = line.Split(' ');
            Console.WriteLine(int.Parse(tokens[0]) + int.Parse(tokens[1]));
        }
    }
}
Python2 while True:
    try:
        (x, y) = (int(x) for x in raw_input().split())
        print x + y
    except EOFError:
        break
