Question

Programming language C++. (Airline Reservations System) A small airline has just purchased a computer for its new au- tomated reservations system. You have been asked to develop the new system. You’re to write an app to assign seats on each flight of the airline’s only plane (capacity: 10 seats).

Display the following alternatives: Please type 1 for First Class and Please type 2 for Economy. If the user types 1, your app should assign a seat in the first-class section (seats 1–5). If the user types 2, your app should assign a seat in the economy section (seats 6–10).

Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available.

Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it’s acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message "Next flight leaves in 3 hours."
