The Phone Management System (Contact Book) is designed in Code:: Block using GCC compiler. It is a simple C console-based project even beginners can give a try.
In this project, you can do the basic operations like in the mobile phonebook. The user can perform insert, modify, list, search and delete in this project. The file handling method and data structure are utilized for storing data and performing the basic phonebook operations in this application.
You can get a clear idea about basic concepts like functions, file handling, and data structure from this c project.
The options to add new records, listing, modifying, and delete is present in the main menu itself. A person's name, father's name, email id, phone number, etc are some of the personal records asked during the addition of records
