need of virtual function

Answer 1

@manoj katari thank u😊😊

Answer 2

Virtual functions ensure that the correct function is called for an object, regardless of the type of reference (or pointer) used for function call.They are mainly used to achieve Runtime polymorphism.Functions are declared with a virtual keyword in base class.The resolving of function call is done at Run-time.

Answer 5

For example you create a function in a base class, and you want to call that function in the base class to the derived classes, it is not possible to do that because you need to declare the function in the base class as a virtual function first, then you can call the function with the base class pointer. Hope this answer your question.
