一个简单的c++程序，大家是怎么结束输入的？

#include <iostream>
    int main()
    {
        int sum = 0, value;
        // read till end-of-file, calculating a running total of all values read
        while (std::cin >> value)
            sum += value; // equivalent to sum = sum + value
        std::cout << "Sum is: " << sum << std::endl;
        return 0;
     }
