What are interfaces in C++?

What are interfaces in C++?

In C++, interfaces are abstract classes that define a contract for derived classes without providing implementation.

How do I create an interface in C++?

You create an interface by declaring a class with only pure virtual functions, like this: class IExample { public: virtual void doSomething() = 0; };.

Can you give me an example of using an interface?

Sure! Here's a simple example: class IShape { public: virtual void draw() = 0; }; class Circle : public IShape { public: void draw() { /* draw circle */ } };.

What are the benefits of using interfaces?

Interfaces promote code reusability, allow for polymorphism, and help in defining clear contracts for classes.
