Bookshop management system using file handling

Last Updated : 08 Jun, 2022

The task is to build the bookshop management system using file handling in C++ that helps to keep track of all the book records in a file. Below are the features to be implemented:

Add new book and the details of the book are:
- Book ID
- Name of book
- Name of Author
- Number of books
Delete a book
Update a book
View all the books
Exit

Approach:

All the functions will be provided under switch cases.
The concept of file handling will be used to write the data in a text file and read the written data as well.
The required function will be written under the switch cases which will be executed as per the input of the user.
Simple file handling concepts like opening a file, closing a file, writing in a file and reading the file, etc. are used to develop the code.
An IDE for compiling C++ language code.

Below is the implementation of the above approach:
