Pure Virtual Member Functions
Explore how pure virtual member functions create abstract classes in C++ and enforce overriding in derived classes. Understand their role in polymorphism and how they enable interface design without object instantiation of base classes.

Abstract Class
We can only make derived class’s objects to access their functions, and we will never want to instantiate objects of a base class, we call it an abstract class. Such a class exists only to act as a parent of derived classes that will be used to instantiate objects.
