C++ : This program will allow the user to keep track of airline reservations. The program should display the seating chart for the airplane. It will use an * to indicate a seat is taken and the # to indicate the seat is available. The program will also display a menu which provides the user with several options. There will be two types of seats in the airplane: first class and coach, each of which will have a different cost. The program must make use of files, arrays and functions.

The airplane will have 5 rows in the first class section with 4 seats in each row, 2 on each side of the aisle and 10 rows in the coach section with 3 seats on each side of the aisle. The prices for all the first class seats will be the same. The first 5 rows of coach will be more expensive than the last 5 rows. The prices for the seats will be stored in a file called SeatPrices.txt and the seat prices will appear in the file like so:

324.23 200.00 150.23

The program should read these values from the file and store the values in an array of doubles. This is an example of the seating chart:

	1 2	3 4
Row 1	# #	# #
Row 2	# #	# #
Row 3	# #	# #
Row 4	# #	# #
Row 5	# #	# #
	1 2 3	4 5 6
Row 6	# # #	# # #
Row 7	# # #	# # #
	Etc.

The menu will provide choices to reserve a seat(s) and display the total number of seats sold (indicating first class and coach), the total number of seats empty in a row, the total number of seats empty in the plane (indicating first class and coach), and the total amount of sales (in dollars).

Validation: The seat requested by the user is a valid row and seat number. The program should also make sure the seat is not already taken.
