Question

我的计算有问题，结果是0。我正在编写一个程序，让用户以小时，分钟和秒为单位输入时间，然后转换并输出以秒为单位的时间。无论输入什么，答案总是给我一个0。

#include <iostream>
#include <cmath>
using namespace std;

int main()
{
    int hours = 0, min = 0, sec = 0, total = 0;

    total = (((hours * 60) * 60) + (min * 60) + sec);

    cout << "Please Enter hours, minutes, and seconds" << endl;
    cin >> hours >> min >> sec;
    cout << "Your time in seconds is" << total;
}

Answer 1

在读取用户输入之前，您正在计算输出。而不是：

total = (((hours * 60) * 60) + (min * 60) + sec);

cout << "Please Enter hours, minutes, and seconds" << endl;
cin >> hours >> min >> sec;

使用

cout << "Please Enter hours, minutes, and seconds" << endl;
cin >> hours >> min >> sec;
total = (((hours * 60) * 60) + (min * 60) + sec);

计算结果意外0
