在c ++中将仪表转换为英尺和英寸存在问题

Question

我的程序可以很好地将英尺和英寸转换为米，但它总是会在仪表上添加一个随机数量的英尺到英尺和英寸的转换。我无法弄清楚为什么。任何建议将不胜感激。 EX）它表示1.3208026m等于8英尺4英寸，实际上是4英尺4英寸。

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


int feet;
double meters, inches;

int main()
{

        cout << "Enter feet " << endl;
        cin >> feet;
        cout << "Enter inches " << endl;
        cin >> inches;

        inches = feet * 12 + inches;
        meters = inches / 39.370;

        cout << setprecision(8) << meters << "m" << endl << endl;

        cout << "Enter meters. " << endl;
        cin >> meters;
        inches = meters * 39.37;
        while (inches > 12)
        {
            if (inches > 12)
                inches = inches - 12;
            feet++;

        }

    cout << feet << " ft and " << setprecision(8) << inches << "in" << endl;

    return 0;
}

Answer 1

首次转换后，您需要将脚重置为零。

Answer 2

    if (inches > 12)
        inches = inches - 12;
    feet++;

没有。需要牙套，否则你的脚就会失败。
