#c++

本文介绍了一个简单的C++程序，用于接收多组输入的整数，并计算每组整数的总和。程序使用标准输入输出，能够处理多行测试用例，每行包含一个整数数量及相应的整数。

Problem Description

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<iostream>

using namespace std;

int main(void)
{
	int n, temp, sum;
	while (cin >> n)
	{
		if (cin.get() == '\n')
			break;
		sum = 0;
		for (int i = 1; i <= n; i++)
		{
			cin >> temp;
			sum += temp;
		}
		cout << sum << endl;
	}

	return 0;
}
