You have been asked to develop the new system. You are to write an application to assign seats in an airline. Assume a small airplane with 28 seats (7 rows 4 wide) as follows:

1  A B   C D

2  A B   C D

3  A B   C D

4  A B   C D

5  A B   C D

6  A B   C D

7  A B  CD

The program should display the seat pattern, with an X marking the seats already assigned.

1  X B   C D

2  A X   C D

3  A B   C D

4  A B   X D

5  A B   C D

6  A B   C D

7  A B   C D

The program then requests a choice of seat. If the seat if available,then the seating display is updated. Otherwise, the program requests another choice of seat. If the user types in a seat that is already assigned, the program should say that that seat is occupied and ask for another choice.

This continues until all seats are filled or until the user says that the program should end.
