What are some examples of object-oriented programming in C++?

Object-oriented programming in C++ includes concepts like classes, inheritance, and polymorphism. For example, you can create a class called 'Animal' and then derive classes like 'Dog' and 'Cat' from it.

Can you explain how inheritance works in this context?

Sure! Inheritance allows a class to inherit properties and methods from another class. For instance, if 'Dog' inherits from 'Animal', it can use the methods defined in 'Animal' while also having its own specific methods.

What is polymorphism and how is it used in C++?

Polymorphism allows methods to do different things based on the object that it is acting upon. In C++, this can be achieved through function overriding and overloading.

Can you give me a code example of polymorphism?

Certainly! Here's a simple example:

class Animal {
public:
    virtual void sound() { std::cout << "Some sound"; }
};

class Dog : public Animal {
public:
    void sound() override { std::cout << "Bark"; }
};

class Cat : public Animal {
public:
    void sound() override { std::cout << "Meow"; }
};

void makeSound(Animal* a) {
    a->sound();
}

In this example, the makeSound function can take any Animal object and call the appropriate sound method.
