Virtual class in a part or used to implement Runtime
polymorphism.Through it dynamically we can access a class or
method of that class.With use of Pointer to base class we
can implememt it.We try to access object of any class
without regarding their class.We are passing object address
in this base class pointer to access a particulat method of
a class at runtime.

Question: Implement a base class Appointment and derived classes Onetime, Daily, Weekly, and Monthly. An appointment has a description (for example, “see the dentist”) and a date and time. Write a virtual function occurs_on(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill a vector of Appointment* with a mixture of appointments. Have the user enter a date and print out all appointments that happen on that date.

Why can't we have instance(stack) of a class as a member of the same class like eg.Class A{A obj;} as we can have self refential pointer
