(Airline Reservations System) A small airline has just purchased a computer for its new au- tomated reservations system. You have been asked to program the new system. You are to write a program to assign seats on each flight of the airline’s only plane (capacity: 10 seats). Your program should display the following menu of alternatives—Please type 1 for "First Class" and Please type 2 for
"Economy". If the person types 1, your program should assign a seat in the first class section (seats 1-5). If the person types 2, your program should assign a seat in the economy section (seats 6-10). Your program should print a boarding pass indicating the person’s seat number and whether it is in the first class or economy section of the plane. Use a one-dimensional array to represent the seating chart of the plane. Initialize all the ele- ments of the array to false to indicate that all seats are empty. As each seat is assigned, set the cor- responding elements of the array to true to indicate that the seat is no longer available. Your program should, of course, never assign a seat that has already been assigned. When the first class section is full, your program should ask the person if it is acceptable to be placed in the economy section (and vice versa). If yes, then make the appropriate seat assignment. If no, then print the message "Next flight leaves in 3 hours." What will be an ideal response?
