Simple Phone Book Management System project in C

Overview of Phone Book Management System project

The is Phone Book Management System project developed in C programming language. This Phone Book using C allows you to perform simple Phonebook operations like on your mobile. Phonebook project is a console application without graphics. It is compiled in Code::Blocks with GCC compiler.

The phonebook Management System project will help you to understand the concept of functions, file handling, and data structure. This Project will show you how to add, list, change, edit, search, and remove data from and into a file. Awesome Quiz Game Project

About Phone book Management System Project using C:

Adding new records, listing them, modifying the old record and updating the records, searching for contacts saved, and deleting the phonebook records are the basic functions that make up the main menu of this Phonebook application.

Personal information such as user name, sex, father’s name, phone number, citizenship number, email address and address are asked while adding a record into the Phonebook.

I have used many functions in this Phonebook Management system project. These functions are very easy to understand as their name only signifies their respective operations. wow!

  • void menu() – This function helps to display the main menu.
  • void start() – This function calls the menu function mentioned above.
  • void back() – This function helps to go back to the start.
  • void addrecord() – It adds a new Phonebook record in the file.
  • void listrecord() – This function is used To view the list of added records in the file.
  • void modifyrecord() – This function is used to modify old records.
  • void deleterecord() – This function helps to delete records from the file.
  • void searchrecord() – This function searches for added records by name.
