Hi I'm trying to understand why my code works but doesn't work for a grade, how to fix it and if you could show the corrected code, why its not working this is for C++.

(Airplane Seating Assignment) | Write a program that can be used to assign seats for a commercial airplane. The airplane has 13 rows, with six seats in each row. Rows 1 and 2 are first class, rows 3 through 7 are business class, and rows 8 through 13 are economy class. Use two parallel arrays: a one-dimensional array to store the row number of the seats (Row #) a two-dimensional array of 13 rows and 6 columns to store the seat assignments (*) and seat letters (A-F) Your program must prompt the user to enter the following information: Reserve a seat (Yes (Y/y) or No (N/n)) Assign ticket type (first class (F/f), business class (B/b), or economy class (E/e)) Select desired seat (1-13 and A-F) Your program must contain at least the following functions: a function to initialize the seat plan. a function to show the seat assignments. a function to show the menu to assign a seat. a function to assign and select your desired seat. a function for each ticket type that determines if a seat is occupied and if that class is full . Output the seating plan in the following form: Seating Plan 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.
