Airline Reservations Program
Produce an airline reservations program to read up to 50 entries from the data file airline.txt into an array of records. Each record will contain the following fields : Flight number (integer), space, Origination point ( String[15]), space, Destination point (String[15]), space, Departure time (String[8]), and Departure date (String[8]).
The program should then provide a user-friendly menu screen to allow the user to
1. Search by Flight number
2. Search by Origination Point
3. Search by Destination point
Choice 1: The program will then perform a binary search by flight number to display the Origination point, Destination point, and Departure time.
Choice 2 & 3: The program will do a serial search by city name, displaying each city with the entered name.
An error message should print if the flight number or city name is not found.

Any help and suggestions would be greatly appreciated i'm stuck. I have been researching sources but i'm having trouble in this subject in general.
Thanks
