This is a console-based Library Management System implemented in C++.
The system uses a Singly Linked List to dynamically manage book records and supports full CRUD operations.
This project demonstrates core Data Structures and Object-Oriented Programming concepts.
- ➕ Add New Book
- 🔍 Search Book by ID
- 📖 Issue Book to Student
- 🔄 Return Book
- 📋 List All Books
- ❌ Delete Book
- 🔢 Total Book Counter
- 🚫 Duplicate ID Protection
- 🧹 Automatic Memory Cleanup (Destructor)
- Singly Linked List
- Dynamic Memory Allocation (
new/delete) - Pointers
- Structs & Classes
- Constructors & Destructors
- Object-Oriented Programming (OOP)
- Menu-Driven Program Design
Since the system uses a singly linked list, operations require linear traversal:
- Add Book → O(n)
- Search Book → O(n)
- Delete Book → O(n)
- Issue / Return → O(n)
- List Books → O(n)
- C++
- GCC (MinGW-w64)
- VS Code
- Windows PowerShell
- Compile the program:
g++ main.cpp -o library- Run the executable:
.\library====== Library Management System ======
1. Add New Book
2. Search for a Book
3. Issue a Book
4. Return a Book
5. List All Books
6. Delete a Book
7. Exit
This project strengthened my understanding of:

- Object-Oriented system design
- Command-line application structure
- File handling for persistent storage
- Sorting functionality
- Fine calculation system
- GUI-based version
- Database integration
⭐ Built to strengthen core Data Structures fundamentals.
