本文介绍了一道简单的输入输出练习题“A+B for Input-Output Practice”，该题旨在帮助初学者熟悉基本的输入输出操作。文章提供了使用C++实现的代码示例。

最近在vjudge上做了一些简单算法入门题目练习，下面进行一个简单的整理归纳，希望与大家一起分享，程序中难免有不足之处，敬请见谅！

A+B for Input-Output Practice (I)

Your task is to Calculate a + b.
Too easy?! Of course! I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim.

Input

The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.

Output

For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.

Sample Input

1 5
10 20

Sample Output

6
30

这是一道简易的输入输出的程序题，该过程应该不是有难度，用c++代码实现如下：

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