Arrays

So I'm almost done with this program but I can't complete the end of it. I was able to do everything except the last part that asks to calculate the number of tickets sold in each level, the sales amount of each level and the sales amount of the entire auditorium. Having arrays in the code confuses me; I don't know how to solve it at all. Any help would be appreciated.

Lab:
Design a program that keeps track of ticket sales for an auditorium. A concert will be a one day event in an auditorium with three levels of seating – floor, balcony, and upper balcony. There are 20 seats for each type of seating.
Write a program that initializes all seats to the ‘*’ (unsold) character. Allow a user to request a seat for a particular seat assignment area. Use a two-dimensional array to keep track of the ticket sales.
- The first dimension indicates the type of seating: F for floor, B for balcony, and U for upper
balcony.
- The second dimension indicates if a seat is sold, using S for sold (remember ‘*’ is unsold).

The pricing schedule is as follows:
- floor seats sell for $30
- balcony seats sell for $20
- upper balcony seats sell for $10 each.

The program must allow input of ticket requests until an X is entered to indicate that no more sales
will be made.

After the close of sales, calculate
- the number of tickets sold in each seating level
- the sales amount sold in each seating level
- the total sales amount for the entire auditorium

Each time a user enters the ticketType at line 69 add one to the count for that type.
