Question

该计划正在以这种方式运作。但我需要改变价格体系。我需要使用priceRead和priceWrite。

priceRead (): double 
priceWrite (in _price: double): void

priceRead：price是读取属性的函数。 priceWrite（double）：price属性是写作的函数。

class Shoes
{
private:
    int size;
    string colour;
    char sex;
    string brand;
    double price;
public:
    Shoes(int _size, string _colour, char _sex, string _brand, double _price) : 
    size(_size), colour(_colour), sex(_sex), brand(_brand), price(_price)
    {}

    void writePrice(double newPrice)
    {
        price = newPrice;
    }

    void readPrice()
    {
        cout << price << endl;
    }
};

注意：

所有的鞋子都有价格，为什么不把它放在基地？
品牌由品牌字符串定义，所有鞋子都相同，因此无需为每个品牌推出新类别。
不需要空的析构函数。
此外，如果在导出时没有重新定义price，则无需在每次从shoeInf派生时重新定义Shoe。
还有一件事：用CapitalLetters启动类名（以那种方式！）。

我需要帮助（写和读函数）c ++
