Consider the Passenger data structure we discussed during the last class. Instead of using "struct", we will use object-oriented "class" Create a hierarchy of 3 classes to support "Party", "Person" and "Passenger", where each inherits from its parent. The attributes that define a Party are: -Party Type Code (P'-person,'O' = organization) -Address (one large string) Phone Number (one string) The attributes that define a Person are: - Date of Birth -First Name Last Name The attributes that define a Passenger are: - Ticket Number - Frequent Flyer Number (valid alphanumeric or N/A) - Ticket Price - Flight Number - Seat Location - Flight Date -Status (T = ticketed, 'H, on hold, 'C' = cancel The following functions are to be implemented: (1) Purchase a ticket. This will create a passenger as an inheritance of both person and party. (2) Change a passenger's seat location. Assume that all seats are available. (3) Cancel the ticket. Provide a user interface via Cout and Cin to obtain the information. Print a confirmation when the transaction is complete. Consider the Passenger data structure we discussed during the last class.
