I need help (write and read function) c++ - c++

Question

The program is working in this way. But I need to change the price system. I need to use priceRead and priceWrite.
priceRead (): double
priceWrite (in _price: double): void
priceRead: price is a function to read the property.
priceWrite (double): price property is a function of writing.
Sorry for bad english. :(

Answer 1

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;
}
};
Notes:
All shoes have a price, so why not just put it in the base class?
Brand is defined by the brand string, all shoes are the same, so no need to derive a new class for each brand.
No need to have an empty destructor.
Also, without this redefinition of price when deriving, you don't have to redefine shoeInf everytime you want to derive from Shoe.
One more thing: Start class names with CapitalLetters (in that style!).
