c++ - 温度转换程序c++

Question

我一直在尝试编写一个温度转换程序来自学 c++ 中的类系统如何将任何给定的温度输入(摄氏度、华氏度和开尔文)转换为其他两个值，然后再次输出所有三个值。但是我无法让我的项目编译，而且我是一个新手，无法自己发现错误。 (相信我，我已经试了一整天了)。 如果有人可以看一下并提出任何建议/改进，我将不胜感激。 顺便说一句，很抱歉没有在我的代码中写任何评论。

#include <iostream>
#include <cstring>
#include <fstream>
#include <cstdlib>
#include <string>

using namespace std;

class Temperature
{
private:
    const double ConversionRate = 0.55555;
    const double AbsoluteZero = 273.15;
    const int TemperatureOffset = 32;

    double InputTemperature = 0;
    double Fahrenheit = 0, Celsius = 0, Kelvin = 0;

public:
    bool setTemperature(double temperature, char temperatureformat)
    {
        bool temperatureConfigured = true;
        if (temperatureformat == 'c') {
            Celsius = temperature;
            Fahrenheit = ((1 / ConversionRate)*(Celsius)) + TemperatureOffset;
            Kelvin = Celsius + AbsoluteZero;
        }
        else if (temperatureformat == 'f') {
            Fahrenheit = temperature;
            Celsius = (ConversionRate*(Fahrenheit - TemperatureOffset));
            Kelvin = (Celsius + AbsoluteZero);
        }
        else if (temperatureformat == 'k') {
            if (temperature >= 0)
            {
                Kelvin = temperature;
                Celsius = Kelvin - AbsoluteZero;
                Fahrenheit = (1 / ConversionRate)*Celsius + TemperatureOffset;
            }
            else {
                temperatureConfigured = false;
                Celsius = 0;
                Kelvin = 0;
                Fahrenheit = 0;

            }
        }
        else {
            temperatureConfigured = false;
        }
    }

    int main()
    {
        double InputReading = 0;
        Temperature temperatureCalculator;
        char temperatureformat = NULL;

        cout << "Please Enter your temperature value" << endl;
        cin >> InputReading;
        cout << "Celsius        - c" << endl;
        cout << "Fahrenheit     - f" << endl;
        cout << "Kelvin         - k" << endl;
        cin >> temperatureformat;


        if (temperatureCalculator.setTemperature (InputReading, temperatureformat)) {
            cout << "Your temperature conversions are" << endl;
            cout << "Celsius:    " << temperatureCalculator.getCelsius() << endl;
            cout << "Fahrenheit: " << temperatureCalculator.getFahrenheit << endl;
            cout << "Kelvin:     " << temperatureCalculator.getKelvin << endl;
        }
        else {
            cout << "Error, your input was invalid" << endl;
        }
    }
}

编译错误如下:

Severity    Code    Description Project File    Line
Error (active)      class "Temperature" has no member "getCelsius"  69

线

if (temperatureCalculator, setTemperature (InputReading, temperatureformat))

我觉得很可疑。为什么 temperatureCalculator 和 setTemperature 之间有逗号？您是不是想用一个“点”(.) 来代替在您的 Temperature 类实例 temperatureCalculator< 上调用类方法 setTemperature/?

如果您发布实际错误，我们可以提供更多帮助。祝你好运!
