Library-Management-System

Overview

The Library Management System is a console-based application developed as a term project for the Programming Fundamentals course. This system is designed to manage the various functions of a library, including book storage, retrieval, lending, and return. It ensures efficient management of library resources and user interactions.

Features

1. User Authentication:

   • Login and Sign-Up functionality.
   • Registered users can access the system's features.
   • Proper messages displayed for unregistered users with prompts to sign up.

2. Main Menu:

   • Provides access to various system features.
   • System remains active until explicitly terminated by the user.
   • Option to return to the menu or re-execute functions after each operation.

3. Book Storage:

   • Books have attributes: title, ISBN number, author, date of publishing, quantity available, and total quantity.
   • Stored in text files on local storage.

4. Book Retrieval:

   • Search for books by title or ISBN number.

5. Book Management:

   • Add new books to the library database.
   • Delete books from the database.

6. Book Lending and Returning:

   • Lend books to users.
   • Return issued books.
   • Track late returns and calculate fines.

Requirements

• Data Structures:

  • Use structs for Book and Lending.
  • Book struct: title, ISBN number, author, date of publishing, quantity available, and total quantity.
  • Lending struct: issued Book, issuing date, date of return, borrower's name, and applicable fine.

• File Storage:

  • Store lending and book structs in respective directories (Lending and Books).
  • Use readdir() function for file access.

• Capacity Management:

  • Library capacity: 10,000 books.
  • Maintain arrays of structs for Books and Lendings in memory.
  • Data should be synchronized with text files upon program start, book addition, and deletion.

• Data Integrity:

  • Ensure changes in memory are reflected in files.
  • Maintain data integrity between memory and disk storage.

• Quantity Management:

  • Decrease available quantity when a book is issued.
  • Prevent issuing if book quantity is zero.
  • Decrease total quantity when a book is deleted.

• Fine Collection:

  • Track fines for late returns.
  • Add fines to library's treasury upon late return.

• Persistent Storage:

  • Ensure data is not lost upon system closure.
  • Load/reload data automatically on system start or database changes.

• Efficient Searching:

  • Implement efficient book search (sorting & binary search).

Bonus Marks

• Implement a Graphical User Interface (GUI) for additional credit.

Development Environment

• IDE: Visual Studio Community Edition.
• Language: C++ (without using STL libraries, OOP concepts, or dynamic memory allocation).
