Ans. 
Virtual functions in OOPS allow a derived class to provide its own implementation of a method defined in the base class.
• Virtual functions are declared in the base class and can be overridden by derived classes.

• They enable polymorphism, allowing objects of different classes to be treated as objects of the same base class.

• The virtual keyword is used to declare a function as virtual in the base class.

• The derived class can...read more
