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.
Output

#include<stdio.h>
int main()
{
int i,m,n,sum;
while(scanf("%d",&m)&&(m!=0))  //當m取值為0的時候停止。
	{
		sum=0;
	for(i=1;i<=m;i++)
	{
		scanf("%d",&n);
		sum+=n;
	}
	printf("%d\n",sum);
	}
	return 0;	
}
