Library Management System (CLI)

This is a simple Command-Line Interface (CLI) Library Management System written in C++.

Note: This project does not include file handling features. Data is stored in memory only during program execution and will be lost once the program exits.

#Features

• Add books with Title, Author, and Book ID
• Update existing book details
• Search for books by Book ID
• Issue and return books
• Display all books with their status (Issued / Available)
• Handles edge cases like:
  • Duplicate Book IDs
  • Issuing an already issued book
  • Returning a book that is not issued
  • Searching or updating a non-existent book

Concepts Used

• Classes and Objects (OOP)
• Encapsulation (keeping book list private inside Library class)
• Constructors (to initialize Book objects)
• Vectors (dynamic storage of books)
• Strings (string class for title and author)
• Loops (for loops for searching and displaying books)
• Conditional Statements (if/else for validations)
• Functions / Methods (separate methods for each operation)
• Menu-driven program with switch-case

How to Run

1. Compile the code using a C++ compiler, for example:

   g++ LibraryManagementSystem.cpp -o library
