Features

The Library Management System offers the following features:

1. Borrow Book: Users can borrow books from the library. They need to enter the Book ID and the quantity they want to borrow. The system checks the availability of the book and updates the inventory accordingly.

2. Return Book: Users can return borrowed books to the library. They need to enter the Book ID and the quantity they want to return. The system updates the inventory with the returned books.

3. Add Book: Librarians can add new books to the library's inventory. They can specify the book's title, author, category, and quantity. The system generates a unique Book ID for the new book.

4. Delete Book: Librarians can delete books from the inventory. They need to enter the Book ID of the book they want to delete. The system prompts for confirmation before deleting the book.

5. Display Books: Users can view a table of available books in the library, including details like Book ID, title, author, category, and quantity.

6. Data Persistence: The system stores book data in a CSV file, allowing data to be saved between program runs.
