Source code for Phone Book
For bca students 👉bca-wala.blogspot.com
About Source Code:-
--This Phone book Project generates an external file to permanently store the user’s data (Name and phone number). The phone book is a very simple C project that will help you understand the core concepts of capacity, record keeping, and data structure. This program will show you how to add, list, edit or alter, look at, and delete data from a record.
Source code is given below:-

If you want to do projects work in C Language. So << visit it >> here you see 15+ projects with there source codes. All Projects divided into three parts such as Beginner, Intermediates, Advance.
All things are write by Ankit Rai urf Ankit King😅
