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 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! An example of runtime polymorphism is using a base class pointer to call a derived class method. For instance, if you have a base class Shape with a virtual function draw(), and derived classes Circle and Square, you can call draw() on a Shape pointer that points to a Circle or Square object, and the correct method will be executed based on the actual object type.

How does polymorphism improve code flexibility?

Polymorphism improves code flexibility by allowing you to write more generic and reusable code. You can use base class references or pointers to work with derived class objects, making it easier to extend and maintain your code without modifying existing code.
