Question

The language is C++ for visual studio express 2013 for windows

create a TicketManager class and a program that uses the class to sell tickets for a performance at a theater.

Here are all the specs. This is an intense program, please follow all instructions carefully.

-I am only creating the client program that uses the class and all it's functions

-The client program is a menu-driven program that provides the user with box office options for a theater and accepts AND validates user inputs, and calls appropriate class functions to carry out desired tasks. The menu options should be , display the seating chart, request tickets, print sales report, and exit program.

-When the user selects the display seating chart option, a TicketManager class function should be called and once the function runs the client program should then display the string from the function.

-When the user selects the request tickets option, the program will prompt the user for the number of seats requested, desired row number and desired starting seat number in the row. A TicketManager ticket function should then be called and passed this user information to handle the request. If the seats requested do not exist or are unavailable and appropriate message should be returned from the function and displayed by the client program. If the seats are available a string will be created by the function that lists the number of requested seats, proce per seat, total price per seats. The user program should then ask the user if they wish to make this purchase.

-If the user indicates they want to make the purchase a TicketManager purchase module will be called to handle the sale. This module will then return a string to the client program.

-When the user selects the sales report option, a TicketManager report module will be called and return a report of sales info to the client program.

-When the user selects the exit program option, the program needs to be able to write the updated seat availability back out to the file. This will be done by the TicketManager destructor.
