Construct an Airlines Reservation System (ARS) program for a flight travel agency. The ARS must keep track of types of planes, destinations, fares, flight booked, date of reservations etc. Your program must be written in C++ object-oriented programming (OOP) and you must show the classes and objects that you use. You can add other functions of the HMS besides the normal functions stated above. As far as possible, use inheritance, polymorphism, and encapsulation in your program.
