Final answer:
The solution involves creating a C program for an airline's reservation system, using an array to track seat assignments on a 6-seat plane, and managing bookings across first class and economy sections, with a fallback option if a section is full.
Step-by-step explanation:
The question deals with writing a C program to manage an airplane's seat reservation system, specifically for a plane with a capacity of 6 seats. The program should provide a menu to allow users to select either first class or economy seating, assign seats accordingly, and generate boarding passes showing the seat number and class. Additionally, the program needs to handle cases where the selected class is full by offering an alternative class or informing the customer about the next flight. The seating chart should be represented by a one-dimensional array initialized to 0, where each element corresponds to a seat that is set to 1 once it is reserved.
Handling seat assignment involves checking the array for the first zero value in the relevant section (indices 0-2 for first class, 3-5 for economy) and setting it to 1 to indicate reservation. If no zeroes are found in the requested section, the customer should be asked if they're willing to switch to the other section. If they agree, the same assignment logic is applied to the alternate section; if they refuse, the message "Next flight leaves in 3 hours" is displayed. The process continues until the user indicates that everyone has boarded, which terminates the program.
