本文介绍了一种通过C语言实现的整数求和程序设计方法。程序接收多组测试用例，每组包含N个整数，然后计算并输出这些整数的总和。示例输入展示了如何构造测试用例，而示例输出则显示了预期的运行结果。

Your task is to calculate the sum of some integers.
Input
Input contains multiple test cases, and one case one line. Each case starts with an integer N, and then N integers follow in the same line.
Output
For each test case you should output the sum of N integers 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
Sample Output
10
15

#include <stdio.h>
int main()
{
	int i,n,num,sum;
	while(scanf("%d",&n)!=EOF)
	{
		if(n==0)
			break;
		sum=0;
		for(i=1;i<=n;i++)
		{
			scanf("%d",&num);
			sum+=num;
		}
		printf("%d\n",sum);
	}
	return 0;
}

#include<stdio.h>
int main()
{
	int i=1,N,t,sum=0;
	while(scanf("%d",&N)!=EOF)
	{
		sum=0;
		for(i=0;i<N;i++)
		{
			scanf("%d",&t);
			sum=sum+t;
		}
	printf("%d\n",sum);
	}
	return 0;
}
