when virtual member function of base class has no important task then it is advisable to overload this virtual member function by any derived class member function .

Helps to design the code with better approach e.g., Abstract Class.

If we have to derive multiple classes from base class and these classes need methods of same type, then in this case take the base class as abstract and derive all the classes from it and implement the methods as desired in derived class.

Pure virtual functions in the base class doesn't have any body.
The main advantage is that if a class has a pure virtual function, then its all derived classes must implement that function in them.
One more advantage is that it tells the user that the object of that class cannot be created.

With the help of pure virtual function the base class pointer object can call the derived class member function....

when we make a function virtual then it is forcing the derived class that it must have to be override and 2ndly this pure virtual fn dont allow to create any object of that class
