I need help passing the "seat array" into the buyticket function. I have made the seating chart but i cant get the '#' to change into '*' when purchased. The seat array should all have the value of the char '#' but it doesnt seem to pass into the buyticket like that. It will always display "sorry this ticket has already been sold" when i try to buy a ticket.
