What is polymorphism in C++?

Can you explain what polymorphism is in C++?

Polymorphism in C++ allows methods to do different things based on the object that it is acting upon. It enables a single interface to represent different underlying forms (data types).

What are the types of polymorphism in C++?

There are two main types of polymorphism in C++: compile-time (or static) polymorphism, which includes function overloading and operator overloading, and run-time (or dynamic) polymorphism, which is achieved through inheritance and virtual functions.

Can you give me an example of runtime polymorphism?

Sure! Here's a simple example: If you have a base class Shape with a virtual function draw(), and derived classes Circle and Square that override draw(), you can call draw() on a Shape pointer that points to either a Circle or a Square, and the correct function will be executed based on the actual object type.

What is the benefit of using polymorphism?

Polymorphism enhances flexibility and maintainability in code. It allows for code that can work with objects of different classes through a common interface, making it easier to extend and modify.
