Problem Description
Your task is to Calculate a + b.

Input
Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair 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
2
1 5
10 20

Sample Output
6
30

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

可能是因为上一道题的知识点我不太了解，所以我感觉这道题比上一道简单的多，也没有什么要说的。
