(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 ch

What will be an ideal response?
