OOP L17 Pointers & References to Base Class, Virtual Functions, and Polymorphism

1. Pointers & References to Base Class
A base class pointer can point to a derived class object but only access base class members unless virtual functions are used.
A base class reference can refer to a derived class object, useful for function arguments.

2. Virtual Functions
Declared using virtual in the base class to enable function overriding in derived classes.
Ensures correct function call via base class pointer/reference at runtime.

3. Polymorphism
Allows calling derived class functions using a base class pointer/reference.
Enables dynamic behavior and flexible code design.
