ubuntu系统下C++变量定义问题

Question

在C++ primer plus计算经纬度的练习题中，

我使用一下代码进行计算

#include <iostream>

int main(){
    using namespace std;
    cout << "Enter a latitude in degrees, minutes and seconds\n";
    int degree;
    cout << "enter a degree:";
    cin >> degree;
    int minutes;
    cout << "enter a minutes:";
    cin >> minutes;
    int seconds;
    cout << "enter a seconds:";
    cin >> seconds;
    // const int trans = 60;
    double degree_print = degree + minutes/60  + seconds/3600;
    cout << degree << " degrees " << minutes << " minutes " << seconds << " seconds " << "= " << degree_print << endl;
    return 0;
}

但最终的计算结果并不正确，而是和我定义的degree保持一致，请问如何处理？感谢。

Enter a latitude in degrees, minutes and seconds
enter a degree:23
enter a minutes:23
enter a seconds:23
23 degrees 23 minutes 23 seconds =23

Answer 1

double degree_print = degree + minutes/60.0 + seconds/3600.0;
由于minutes和seconds都是int类型，两个整数相除是整除，所以要改为60.0和3600.0，否则后面两个除法结果都是0
