Library Management System (C++)

🎓 Course Project: Computer Programming (Dec 2023) 📅 Date: December 2023

A robust, console-based Library Management System developed in C++. This application handles book inventory, reader management, and borrowing records using file-based persistence.

👨‍💻 Project Background & Contribution

This project was developed as a group assignment for the Computer Programming course.

My Key Contributions:

• Search Engine (Find Module): Designed and implemented the core search logic, allowing users to find books by Title, Author, Publisher, or ISBN with fuzzy matching support.
• Admin Management (Admin Module): Developed the full CRUD (Create, Read, Update, Delete) functionality for the book inventory, enabling administrators to manage the library database efficiently.

🚀 Features

• Smart Search: Find books by Title, Author, Publisher, or ISBN (supports spaces in keywords).
• Inventory Control: Real-time updates of book stock when books are borrowed or returned.
• Role Management: Distinct functionalities for Admins (Book Management) and Readers (Borrowing/Returning).
• Data Persistence: Uses text files (.txt) to permanently store data, ensuring records are saved between sessions.

🛠️ Tech Stack

• Language: C++ (Standard 11/14/17)
• Build System: CMake
• IDE: CLion
• Data Handling: File I/O with Tab-Separated Values (TSV) to handle complex string inputs.

🔧 How to Run

1. Clone the repository:

   git clone [https://github.com/YOUR_USERNAME/LibrarySystem.git](https://github.com/YOUR_USERNAME/LibrarySystem.git)

2. Open in CLion (or compile via CMake).
3. Build & Run.
   • Note: Ensure the data/ folder is in the working directory so the program can load the databases.

📝 Usage Guide

1. For Admins: Log in to access the Book Management Menu. You can add new books, update existing stock/info, or delete obsolete records.
2. For Readers: Use the Search function to find books and proceed to Borrow or Return using the Book ID.

📂 Project Structure

The project follows a modular C++ structure separating logic, headers, and data.
