Virtual Functions
Last updated: Aug 7, 2022

Virtual Functions

A virtual function is a member function within the base class that we redefine in a derived class. It is declared using the virtual keyword. When a class containing a virtual function is inherited, the derived class redefines the virtual function to suit its own needs. Basically, a virtual function is used in the base class in order to ensure that the function is overridden. This especially applies to cases where a pointer of the base class points to an object of a derived class.
