When choosing seat, indicate the row and column for the location; when choosing the price, like computer find the first available price; mark the sold seats by changing the price to 0. When a user specifies a seat, make sure it is available. Use loop to determine whether continue to order or not. In each time, the seating chart should be displayed for user.
