Hello Eiffel Enthusiasts!

I'm currently working on an Eiffel programming assignment and could use some guidance. Here's the challenge:

Assignment Task:

Develop an Eiffel program that simulates a simple library system. The program should allow users to:

1. Add a new book to the library inventory.
2. Check out a book.
2. Return a book.
3. Display the list of available books.

I'm a bit stuck on how to structure the classes and implement the functionality efficiently. Could you please share your expertise, code snippets, or any tips on how to approach this assignment in Eiffel?

Your assistance would be greatly appreciated!

Greetings, Eiffel Explorer!

Absolutely, I'm here to help you navigate through your Eiffel assignment. Let's break it down:

Step 1: Class Structure and Features

Here's a basic outline of the classes you might consider:

```eiffel
class
LIBRARY_ITEM

feature -- Access
title: STRING

feature -- Initialization
make (a_title: STRING)
do
title := a_title
end
end

class
BOOK
inherit
LIBRARY_ITEM

feature -- Access
is_checked_out: BOOLEAN

feature -- Initialization
make (a_title: STRING)
do
inherit
make (a_title)
is_checked_out := False
end

feature -- Operations
check_out
do
is_checked_out := True
end

return
do
is_checked_out := False
end
end

class
LIBRARY
feature -- Access
books: LIST [BOOK]

feature -- Initialization
make
do
create books.make_empty
end

feature -- Operations
add_book (a_book: BOOK)
do
books.extend (a_book)
end

display_available_books
do
-- Iterate through books and display available ones
end
end
```

Step 2: Using the Classes in Main Program

Now, in your main program, you can create instances of these classes and use their features to perform the required operations:

```eiffel
class
MAIN_PROGRAM

feature -- Initialization
make
local
library: LIBRARY
book1, book2: BOOK
do
create library.make
create book1.make ( " Introduction to Eiffel " )
create book2.make ( " Advanced Eiffel Programming " )

library.add_book (book1)
library.add_book (book2)

-- Perform operations like check_out, return, and display_available_books
end
end
```
