📚 Library Management System

A robust Library Management System developed in C++. This project was built as a term project for the Programming Fundamentals course at FAST-NUCES, demonstrating mastery of procedural programming, file handling, and algorithm efficiency without the use of Object-Oriented Programming (OOP) or pointers.

🚀 Project Overview

This system serves as a digital catalog for managing library operations. It utilizes File Handling to persistently store book records and lending history, ensuring data integrity even after the program terminates. It is optimized to handle up to 10,000 records using efficient searching algorithms.

✨ Key Features

🔐 User Access

• Authentication: Secure Login and Sign-Up mechanism.
• Role Validation: Ensures only registered users can perform operations.

📖 Book Management

• CRUD Operations: Add new books, delete obsolete records, and update stock quantities.
• Smart Search: Search books by Title or ISBN.
• Optimization: Implements Binary Search and Sorting Algorithms for rapid retrieval.

🔄 Circulation System

• Book Lending: Assign books to users with a timestamp.
• Returns & Fines: Tracks return dates and automatically calculates fines for late submissions.
• Inventory Tracking: Automatically decrements/increments stock upon borrowing/returning.

⚙️ Technical Implementation (The "Under the Hood")

This project was built under strict constraints to demonstrate core programming logic:

• No OOP (Classes): Built entirely using structs and functions.
• No Pointers/Vectors: Memory managed using static arrays.
• Data Structures:
  • struct Book: Stores Title, ISBN, Author, Publication Date, and Stock.
  • struct Lending: Tracks Borrower Name, Issue Date, Return Date, and Fines.
• Persistence: Custom text-based file database stores data in Books/ and Lending/ directories.

🛠️ Setup & Installation

Prerequisites

• Visual Studio Community Edition (Recommended IDE).
• Dependencies:
  • dirent.h (For directory traversal).
  • stdfx.h (Standard precompiled header).

Installation Steps

1. Clone the repository:

   git clone [https://github.com/MiraalFatima/Library-Management-System.git](https://github.com/MiraalFatima/Library-Management-System.git)

2. Library Setup:
   • Ensure dirent.h is included in your include path if you are on Windows/Visual Studio.
3. Compile & Run:
   • Open the .sln file in Visual Studio.
   • Build the solution (Ctrl + Shift + B).
   • Run the Local Windows Debugger (F5).
