virtual function is defined as virtual is a keyword which is used when one function or method is used in both base class and drived class at a time then, during compile time compiler cannot distinguish that which one compile or run first.
then to distinguish that problem the programmer use special keyword in base class or in derived class that is known as "VIRTUAL" keyword.
Due to this keyword the compiler always compiles the assigned virtual keyword method or function and this is called as virtual function.

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.
