Background:

$[$Hotel Reservation System$]$

The purpose of a Hotel Reservation System is to streamlines room management for your hotel. Imagine a building block approach: the system is made up of interconnected parts representing the hotel itself $($Hotel class$),$ its floors $($Floor class$),$ and individual rooms $($Room class$).$ Each hotel can have many floors, and each floor holds multiple rooms. Floors are linked together like a chain, making it easy to navigate the hotel virtually.

Rooms keep track of who's staying and when, while Reservations hold guest details like names, room numbers, and stay duration. Guests can use the system to book available rooms, and staff can easily view the current status of each room, including occupancy and reservation information. This modular design keeps things organized and efficient, ensuring a smooth experience for both guests and staff.

Problem:

Write a complete C$++$ program that implements Hotel Reservation System as a linked list to maintain an updated information for a reserving room. The structure of the data is as in the following figure:
