A+B for Input-Output Practice (IV)

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.
输入包含多个测试用例。每个测试用例包含一个整数N，然后在同一行中跟随N个整数。以0开始的测试用例将终止输入，并且不处理此测试用例。

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.
对于每组输入整数，您应该将它们的和输出到一行中，并为输入中的每一行输出一行。

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

Sample Output
9
16

#include
int main()
{
     
    int n;
    int num;
    int sum;
    while(scanf("%d",&n) != EOF)
    {
     
        sum = 0;
        if(n == 0)
            break;
        else
            while(n--)
            {
     
                scanf("%d",&num);
                sum += num;
            }
        printf("%d\n",sum);
    }
    return 0;
}
