Write a class that can be used to assign seats for a commercial airplane. The airplane has

13 rows, with 6 seats in each row. Row 1 and 2 are first class; the remaining rows are

economy class. Also, rows 1 through 7 are nonsmoking. Your program must prompt the

user to enter the following information:

a. Ticket type (first class or economy class)

b. For economy class, the smoking or nonsmoking section

c. Desired seat (example: 7F)

Output the seating assignment in the following form:

A

B

C

D

E

F

Row 1 * * X * X X

Row 2 * X * X * X

Row 3 * * X X * X

Row 4 X * X * X X

Row 5 * X * X * *

Row 6 * X * * * X

Row 7 X * * * X X

Row 8 * X * X X *

Row 9 X * X X * X

Row 10 * X * X X X

Row 11 * * X * X *

Row 12 * * X X * X

Row 13 * * * * X *

Here, * indicates that the seat is available; X indicates that the seat is occupied. Make this

a menu-driven program; show the users choices and allow the user to make the

appropriate choices.

2. Theres no attribute required this time.

3. Define the constructor.

a. ASA: Constructor for objects of class ASA declare and initialize the local

variables. Initialize the seats array with '*' character. Until a user choose

to stop the program, repeat the program. First display the current seat

assignment map. Display the menus and instructions, then a user choose

one from the menu then type in required seat number. Next assign the

user to the user's requested seat. Then report the result.

4. Define the methods as following:

a. printSeats method: This method gets one parameter of character array to

get the current seat assign status. Doesnt return at all. Must generate the

output like below:

A B C D E F

Row 1 * * * * * *

Row 2 * * * * * *

Row 3 * * * * * *

Row 4 * * * * * *

Row 5 * * * * * *

Row 6 * * * * * *

Row 7 * * * * * *

Row 8 * * * * * *

Row 9 * * * * * *

Row 10 * * * * * *

Row 11 * * * * * *

Row 12 * * * * * *

Row 13 * * * * * *
