2. Ticketing and Reservation system

Our older generations will vouch for how tedious long distance travel would be prior to the digital era. Not only would the journey be long but also getting access to the modes of transport used to be rather painstaking. Long queues at the booking centers, which too would be situated fairly away from usual residential areas, a limited number of seats and the highly inefficient and painstakingly slow ticketing process would dampen the spirits of traveling.

With e-ticketing systems, access to air, rail, and bus journeys have not only increased considerably but also people can easily book tickets on their own without having to depend on middle persons and agents. As increasing numbers of booking platforms emerge with more tech savvy features, we have C programming to thank. The source code in C can be adopted to a seamless booking process for not only air, rail or bus tickets but also car rentals.

In fact, using the same codes and libraries, developers may also consider developing e-booking platforms for hotel bookings, restaurant tables and so much more. Strings and arrays in C programming are extremely helpful to ease out the booking window for both web and mobile phone users.

Further, if the developers strip external file storage from the source code, then the user data will also be erased once the ticket has been booked. This eliminates the fear of a data privacy breach for the users.

This system helps the users to easily check the book tickets, bus schedule, the bus status board, and cancel reservations. When buying tickets, the user should first enter the bus number. Subsequently, the system will show the entire number of bus seats and the passengers’ names. The user then needs to enter the seat number, the number of tickets, and the person’s name.

It is one of the fundamental C language projects for beginners that uses if-else logic, arrays, loop statements, and different functions like cancel(), login(), etc.  This C project helps you to simulate a bus reservation system. This system takes input like the number of seats, bus type, the price of each seat, luggage load, individual bags permitted per ticket, etc. 

These inputs help you to set up a reservation system wherein you will display a list of available seats, accept reservation requests, and process them. Subsequently, you can add more functionality like a refund, cancelling a reserved seat, bulk booking, etc. Moreover, it assists you to determine seat availability and search for the booking information. You can use SQLite DB for data storage or use simple file handling.
