Question

Can you help us!! Thank you!

Write a program that can be used by a small theater to sell tickets for performances. The program should display a screen that shows which seats are available and which are taken. Here is a list of tasks this program must perform • The theater's auditorium has 15 rows, with 30 seats in each row. A two dimensional array can be used to represent the seats. The seats array can be initialized with # which means all seats are available. • The prices for each row can be stored in a separate array. All seats in given row are the same price, but different rows have different prices. • The program should display a menu includes options to o Display the seating chart: o View the ticket price for each row o Purchase ticket o View ticket sales report (total price for ticket purchased) o Exit the program . When the user selects the display seats menu option, the seats chart similar to the one shown below should be displayed. It should indicate which seats are already sold (*) and which are still available for purchase (#).
