A+B for Input-Output Practice (V) （C语言代码）

参考代码:

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