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.

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.

• Secure login.
• Book Management:
  • Add new book records (ID, name, author, category, location, price, available quantity).
  • Modify existing book details.
  • Search books by ID, name, category, author, or price.
  • Delete book records.
• Borrower Management:
  • Add new borrowing records (student name, student ID, book name, book ID, borrow date, return date).
  • Modify existing borrowing record details.
  • Search borrowing records by student ID, student name, or book ID.
  • Search for outdated borrowing records.
  • Delete borrowing records.
• Sign out / Exit.

• Secure login or Sign up for a new account.
• Search books by ID, name, category, author, or price.
• View trending books (based on view count).
• Sign out / Exit.

• A C compiler (like GCC, MinGW, or the compiler integrated into an IDE like Visual Studio or Code::Blocks).
• Windows Operating System (if using the MessageBox feature as-is).

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.

• Username: Vnuis
• Password: Vnu.edu.vn

This project was created for educational purposes as part of the Programming I course at VNU-IS.
