From the Appointment class you developed in the previous assignment, derive two classes: ClientSession and CourtSession (instead of Session class). The ClientSession will have all the data and functions of Session (as in previous assignment). CourtSession will also have courtName and location (both c-strings), in addition to the Session previously done. They must also have the same functions as before, with get and print functions of CourtSession taking the additional information into account.

In main, create an array of Appointment pointers and ask the user repeatedly if they want to enter a ClientSession or CourSession. In either case, create the requested session, read the required information, save the pointer in the array of Appointment pointers, and when done, list all created sessions, printing all their information. Also, print the calculated charge for each session.

For example:

It might show:

Client ID, client name, date, time

Hours spent, cost per hour, total charges

Client ID, client name, Court name, Court location, date, time

Hours spent, cost per hour, total charges

Client ID, client name, date, time

Hours spent, cost per hour, total charges

Client ID, client name, Court name, Court location, date, time

Hours spent, cost per hour, total charges
