Description

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

 

题解：此题和hdu1000题意基本一样，是不是加了一些关于acm的话就吓到你了，其实他们的代码完全相同

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