suppose A is a base class and B is the derved class. Both have a method foo which is defined as a virtual method in the base class. You have a pointer of classs B and you typecast it to A. Now when you call pointer->foo, which method gets called? The next part of the question is, how does the compiler know which method to call?

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.
