解决输入一组数据计算负值个数，没有反映的问题

输入一组数值之后，可以输入Ctrl+X,然后enter便出现结果

# include <iostream> //输入一组数据之后，要输入Ctrl+X，然后键入enter便出现结果int main() { int amount = 0, value; while (std::cin >> value)if (value < 0) ++amount; std::cout << "Amountof all negative values read is " << amount << std::endl; system ("pause");return 0;}
