Question

Working code without any errors a. b. Sufficient comments for user to read your code and analyze your logic. c. Proper indentation. d. Proper use of variables and identifiers. e. Use of Functions, array, loop, conditional stalemates. f. Submit your working code before the deadline. Program 16/Chapter 8 (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. Your program must prompt the user to enter the following information: a. Ticket type (first class, business class, or economy class) b. Desired seat Output the seating plan in the following form: 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 Here, * indicates that the seat is available; X indicates that the seat is occupied. Make this a menu-driven program; show the user's choices and allow the user to make the appropriate choices.
