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' Address (one larga string) Phone Number (one string organization) 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
