Library Management System (C)

A console-based Library Management System written in C for managing book records and borrower information. This project was developed as the final project for the Programming I course (INS2020) at VNU International School.

Description

This application provides a simple command-line interface for librarians (administrators) and readers (users) to interact with a library database. Administrators can manage the book inventory and track borrowed books, while readers can search for books and view popular titles. The system uses text files (book.txt, record.txt, account.txt) for persistent data storage.

• Windows Operating System (if using the MessageBox feature as-is).

How to use

1. Clone the repository:

   git clone https://github.com/duythucvnu/vnuis-lms-c.git
   cd vnuis-lms-c

2. Execute the compiled file from your terminal:

   ./lms.exe

   or on Windows command prompt:

   lms.exe

3. The application uses the following data files in the same directory:

   • account.txt: Stores user login credentials.
   • book.txt: Stores book inventory details.
   • record.txt: Stores borrowing records. The program will create these files if they don't exist.
