: In preparation for the release of Avengers 4 next summer, you have been hired by the owner of a very small movie theater to develop the backend for an online ticket reservation system. The program should display the current seating arrangement and allow the patron to select seats. A report should be generated at the end of the program to specify for each individual auditorium and overall for all auditoriums how many seats were sold/unsold and how much money was earned.

The seating arrangement for the auditorium will be stored in a file named A1.txt Each line in the file will represent a row in the auditorium. The number of rows in the auditorium is unknown to you. o There will be a newline character after each line in the file except for the last line which may or may not have a newline character. The number of seats in each row of the auditorium will be the same. No row will have more than 26 seats. Do not hold the auditorium in memory (-15 points if auditorium is held in memory) o Utilize random file access to view and modify the auditorium Empty seats are represented by a period (.). Reserved seats are represented by a letter (A, C or S) in the file o This will be used to create reports o A =adult o C = child o S = senior Reserved seats will be represented by a hashtag (#) on the screen o The user does not need to know what type of ticket was sold, just that a seat is reserved. There is no need to worry about multiple screenings or reserving seats on a specific day.

Ticket prices are as follows: o Adult - $10 o Child - $5 o Senior - $7.50 User Interface and Input: Present a user-friendly menu system for the user. 1. Reserve Seats 2. Exit Loop the menu until the user decides to quit. Imagine this is for a ticket kiosk in the lobby of the theater. If the user wants to reserve seats, display the current seating availability for that auditorium. An example seating chart is provided below for an auditorium with 5 rows and 20 seats per row. ABCDEFGHIJKLMNOPQRST

1 ...##..#####........

2 ########....####..##

3 .........##.........

4 #.#.#.#.#.#.#.#.#.#.

5 ########.#####.##### The rows are numbered and the seats are identified in each row by a letter of the alphabet After the seating chart has been displayed, prompt the user for the following information in the order below: Row number

Starting seat letter

Number of adult tickets

Number of child tickets

Number of senior tickets Assume that the user wants to reserve sequential seats to the right of the first seat entered. Adult tickets will be reserved first, followed by child and then senior. All seats must be open for a reservation to be processed. Remember to mark the seat with the appropriate letter to show it has been reserved. If the desired seats are not available, check for the best available seats that meet their criteria on that row only. The best available seats are the seats closest to the middle of the row measured by the distance from the center of the available selection to the middle of the row. If alternate seats are available, prompt the user to enter a Y to reserve the best available or N to refuse the best available. Once the selection has been processed, return to the main menu. If there are no alternate seats available, display an appropriate message to the user instead of a prompt and return to the main menu. When prompting the user for input, expect anything. Do not assume any input will be valid. If you ask for a number, the user could put in a floating point number, symbols or maybe even the Gettysburg Address (or at least a sentence or two). Make sure that the user selection does not go out of bounds of the auditorium. If invalid input is entered, loop until valid input is received. User Interface Workflow: Please do not add extra prompts since this will cause a mismatch in the input which will either force the program to throw an exception or cause the program to perform an unintended operation. Display main menu Prompt for input If user is reserving tickets o Prompt for row o Validate loop until valid Valid row = row number listed in auditorium display o Prompt for starting seat o Validate loop until valid Valid seat = seat number listed in auditorium display o Prompt for number of adult tickets o Validate loop until valid Valid ticket number = number >= 0 o Prompt for number of child tickets o Validate loop until valid Valid ticket number = number >= 0 o Prompt for number of senior tickets o Validate loop until valid Valid ticket number = number >= 0 o If seats unavailable Display best available Prompt user to reserve (Y/N) o If reserved, confirm reservation o Return to main menu Loop to top of workflow until user selects exit Output: At the end of the program, display a formatted report to the console. Make sure each column lines up properly (no jagged columns). Include the following information in the order given: Total Seats in Auditorium Total Tickets Sold Adult Tickets Sold Child Tickets Sold Senior Tickets Sold Total Ticket Sales total amount of money collected for tickets in the auditorium All values except total ticket sales will be an integer value. Total ticket sales will be a floating-point value rounded to 2 decimal places and formatted with a dollar sign before the first digit of the number.
