Airlines Reservation system using C with Source Code

Introduction :

Airlines Reservation System deals with the various activities related to the flights. It is a web-based flight booking agency that is used to conduct flight bookings. Earlier all activities were done manually, which was very time-consuming and costly. But the Airlines Reservation System simplifies the booking process and is helpful for both travel agencies and travelers. This project is designed in a way that includes faster system accuracy, and reliability, and makes it more informative.

gameLoop()

Explanation:

1. All the required header files are used. As getch() function is used in our code and it is a pre-defined non-standard function that is defined in conio.h header file.

2. Arrays are used for saving the data that the user will input like passport [20], and name [20].

3. do-while loop is used so that it will execute the code block once, before checking the condition is true and then it will repeat the loop as the user require.

4. Switch case is used to handle the cases according to the user’s choice.

5. As users will reserve the seats it decreases the availability of seats by one.

6. Finally the project is ready to serve the Airline Reservation System.
