Question

This is an exercise for 2-Darray application and the ‘continue’ statement usage inloop. Before you get onboard an airport, you’ll have to get aboarding card in the airport. There is a machine with touch screen,like an ATM in a bank branch. In that touch screen it will displayall available and taken seats. You job is to write such a programto assign passengers seats for a small airplane with seat numberingas 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 C D
Your program should display the seat pattern, with ‘X’marking the seat already taken. For example, after seats 1A, 2B,and 4C are taken, the display should look like this:
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
After displaying the seats available, the program prompts for theseat desired, the user types in a seat, and then the display ofavailable seats is updated. This continues until all seats arefilled or until the user signals that the program should end. Ifthe user types in a seat that is already assigned, the programshould say that seat is occupied and ask for another choice.
