How do I implement abstraction in C++?

Abstraction in C++ can be implemented using abstract classes and interfaces. Would you like an example?

Yes, please provide an example of an abstract class.

Sure! Here's a simple example:

class Shape {
public:
    virtual void draw() = 0; // pure virtual function
};

class Circle : public Shape {
public:
    void draw() override {
        // implementation for drawing a circle
    }
};

This defines an abstract class Shape with a pure virtual function draw.

What is a pure virtual function?

A pure virtual function is a function declared in a base class that has no implementation. It forces derived classes to provide an implementation.
