Polymorphism in C++ can be implemented using function overloading, function overriding, and virtual functions.

• Use function overloading to have multiple functions with the same name but different parameters.

• Use function overriding to have a function in a derived class with the same name and parameters as a function in the base class.

• Use virtual functions to achieve runtime polymorphism by allowing a function in a base class to be overridden in a derived class.

Method overloading is having multiple methods in the same class with the same name but different parameters. Method overriding is redefining a method in a subclass with the same signature as in the superclass.

• Method overloading allows a class to have multiple methods with the same name but different parameters. Example: void print(int a) and void print(int a, int b).

• Method overriding occurs when a subclass provides a specific implementation of a method that is already provide...read more
