Problem Description

Your task is to Calculate a + b.

 

 

Input

Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.

 

 

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 0 0

 

 

Sample Output

6 30

 

 

解题思路：输入A,B两个整数，求和，当A和B都为0的时候结束。注意判断EOF。

代码如下

int main(void)
{
    int a, b, n;
    while (scanf_s("%d %d", &a, &b) != EOF)
    {
        n = 0;
        n = a + b;
        if (n == 0)
            break;
        else
        printf("%d\n", n);
    }
    return 0;
}
