Telecom Billing Management System in C with Source Code

This Telecom Billing Management System Project in C is a consoled based application created using c programming language. This system is a simple mini project and compiled in Code::Blocks IDE using GCC compiler. Telecom Billing System is a small project, you may perform and handle billing processes in the same way as telecom businesses do. You can add records with names, phone numbers, and payment amounts here. Existing records can be viewed, modified, searched, and deleted.

You can also make a payment using your phone number rather than your name. All data that is added or updated is saved in a file. This project will teach you how to use file handling to add, list, modify, search, and delete records.

A Telecom Billing Management System Project using C language is an easy project for beginners to learn how to build a web-based C language project. We will provide you with the complete source code for the C project so that you can easily install it on your machine and learn how to program in C language.
