How do I design a class in C++ using OOP principles?

To design a class in C++, start by defining its attributes and methods. What functionality do you want to include?

I want to create a class for a 'Car' that has attributes like 'make', 'model', and 'year'.

Great! You can define the class like this:

class Car {
public:
    std::string make;
    std::string model;
    int year;

    Car(std::string m, std::string mo, int y) : make(m), model(mo), year(y) {}
};

Would you like to add any methods to this class?

Yes, I want to add a method to display the car's details.

You can add a method like this:

void displayDetails() {
    std::cout << "Make: " << make << ", Model: " << model << ", Year: " << year << std::endl;
}

This will print the car's details when called. Do you need help with anything else?
