PRG255 - Assignment
Title: Econo-Flight Airline Reservation Program
Write the Econo-Flight Airline Reservation Program with the following features:
Description : The Econo-Airlines fleet consists of one plane with a seating capacity of 12.
It makes one flight daily.
The aircraft seating is arranged in 6 rows with 2 seats per row. The program uses an array of 12 structures. Each structure holds a seat identification number, a marker that indicates whether the seat is assigned, the last name of the seat holder, and the first name of the seat holder.
The program is to displays the following menu. Use a do while loop and a switch to make the selection. The selection must NOT be case sensitive. Each selection should call a different function.
To choose a function, enter its letter label:
- Display ALL seat assignments (including Empty).
- Show ONLY a list of empty seats and show total of empty seats
- Show ONLY the assigned seats with name of person and total assigned.
- Assign the customer to an empty seat.
- Delete ONE seat assignment.
- Delete ALL seat assignments.
- Quit program.
Note all data must be saved to a file.
- The program must successfully execute the premise of the menu.
- Data is to be saved to a file between runs. When the program is restarted,
it must first load the last status.
Do not use global variables. (except for the structure definition).
Submission requirements:
The first page is the cover page. (Word or PDF document)
- Name of the Project
- Name of your Professor
- Your name and student number.
