C Language : Airline Reservations System [已解决]

蜡笔小烦

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 “smoking”

Please type 2 for “nonsmoking”
If the person types 1, then your program should assign a seat in the smoking section (seats 1-5). If the person types 2, then your program should assign a seat in the nonsmoking section (seats 6-10). Your program should then print a boarding pass indicating the person’s seat number and whether it is in the smoking or nonsmoking section of the plane.
Use a single-subscripted array to represent the seating chart of the plane. Initialize all the elements of the array to 0 to indicate that all seats are empty. As each seat is assigned, set the corresponding elements of the array to 1 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 smoking section is full, your program should ask the person if it is acceptable to be placed in the nonsmoking section (and vice versa). If yes, then make the appropriate seat assignment. If no, then print the message”Next flight leaves in 3 hours”.
