What are interfaces in C++?

What are interfaces in C++?

In C++, an interface is a class that contains only pure virtual functions. It defines a contract for derived classes.

How do I create an interface in C++?

To create an interface, declare a class with only pure virtual functions using the syntax: class InterfaceName { public: virtual void functionName() = 0; };.

Can you give me an example of an interface?

Sure! Here's a simple example:

class Drawable {
public:
    virtual void draw() = 0;
};

What is the purpose of using interfaces?

Interfaces allow for abstraction and define a common protocol for different classes, promoting code reusability and flexibility.
