Problem Description
Your task is to Calculate the sum of some integers.
 

 

Input
Input contains multiple test cases. Each test case contains a integer N, and then N integers follow in the same line. A test case starting with 0 terminates the input and this test case is not to be processed.
 

 

Output
For each group of input integers you should output their sum in one line, and with one line of output for each line in input. 
 

 

Sample Input
4 1 2 3 4 5 1 2 3 4 5 0
 

 

Sample Output
10 15

 解题思路:先输入一个N,然后输入N个整数,N个整数相加的和输出出去。N为0的时候结束输入。

代码如下

#include <stdio.h>
int main(void)
{
    int a;
    int i, sum;
    int n;
    while (scanf_s("%d", &n) != EOF)
    {
        if (n != 0)
        {
            sum = 0;
            for (i = 0; i < n; i++)
            {
                scanf_s("%d", &a);
                sum += a;
            }
            printf("%d\n", sum);
        }
        else
            break;
    }
    return 0;
}
