Question

In C++.

Write a program that can be used to assign seats for a commercial airplane and print out the ticket total. The airplane has 13 rows, with row 7 being the Emergency Exit row. Each row has 7 seats, there are two seats on each side of the plane and three seats in the middle with aisles on both sides. Rows 1 and 2 are considered first class with tickets for this specific  flight being $872.00 round trip. Rows 3 - 6 are business class with tickets at $697.60, and rows 7 through 13 are economy class with tickets at $436.00, however Emergency Exit row seats have an extra fee of $32.00 and passengers purchasing those seats must confirm that they are 16 years of age or older. Your program must prompt the user to enter the following information:

a. Ticket type (first class, business class, or economy; keep in mind the special circumstances for emergency row seats)

b. Desired seat(s)

Once all seats are selected there should be a 9% tax and the total should be displayed to the user.

Output the seating plan in the following form:

	A	B	|	C	D	E	|	E	F
ROW 1	*	X	|	*	*	*	|	X	X
ROW 2	*	X	|	*	X	*	|	*	*
ROW 3	*	*	|	X	X	X	|	*	*
ROW 4	X	X	|	*	*	*	|	X	*
ROW 5	*	X	|	*	*	X	|	*	*
ROW 6	*	X	|	*	*	*	|	X	*
ROW 7	*	*	|	*	*	*	|	*	*
ROW 8	*	X	|	*	*	X	|	X	*
ROW 9	X	*	|	*	*	*	|	X	X
ROW 10	*	X	|	*	*	X	|	*	*
ROW 11	X	X	|	*	*	*	|	*	X
ROW 12	*	*	|	X	*	X	|	*	*
ROW 13	*	*	|	*	*	*	|	*	X

Here the * indicates that a seat is available; X indicates that the seat is occupied; | indicates the aisle of the plane. Make this a menu-driven program; show the user's choices (this is your starting seats, so make sure that seats already taken remain taken) and allow the user to make the appropriate selection of seats.
