Design and implement a program that assigns seats on an airplane. Assume the airplane has 20 seats in first class (5 rows of 4 seats each, separated by an aisle) and 180 seats in economy class ( 30 rows of 6 seats each, separated by an aisle). Your program should take three commands: add passengers, show seating and quit. When passengers are added, ask for the class (first or economy), the number of passenger traveling together (1 or 2 in first class; 1 to 3 in economy), and the seating preference (aisle or window in first class; aisle, center or window in economy). Then try to find a match and assign the seats. If no match exists, print a message.
