Solve the question using 2 dimensional pointers. You must use new and delete operator in the program and try to make an easier logic of the problem.

Q2. Write a C++ program using a dynamic array (or arrays) to assign passengers seats in a Bus and your program will ask the user how many rows the Bus has and will handle that many rows (Assume the Bus does not always have the same rows). (5 points)
Expected output: Assume a small Bus with seat numbering 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 C D
8 A B C D
9 A B C D
10 A B C D
The program should display the seat pattern, with an X marking the seats
already assigned. For example, after seats 1A, 2B, and 4C are taken, the
display should look like this: (5 points)
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
8 A B C D
9 A B C D
10 A B C D
After displaying the seats available, the program prompts for the seat
desired, the user types in a seat, and then the display of available seats is
updated. This continues until all seats are filled or until the user signals
that the program should end. If the user types in a seat that is already
assigned, the program should say that the seat is occupied and ask for
another choice. (10 points)
