Question

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 . 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:

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.

SEATPRICES.TXT  the numbers in the file is below

324.23
200.00
150.23

12 34 Row 1 ## ## Row 2 ## ## Row 3 ## ## Row 4 ## ## Row 5 ## ## 123 456 Row 6 ### ### Row 7 ### ### Etc.
