Hotel Management System

This project is a simple Hotel Management System written in C++. It includes functionalities such as booking rooms, checking in, checking out, and inquiring room status.

Features

• Room Booking: Allows customers to book rooms based on room standards.
• Check-In: Handles customer check-in, either with a prior booking or without.
• Check-Out: Manages customer check-out, including billing based on actual stay duration.
• Inquiry: Provides information on room status (available, booked, occupied) and customer details.

Usage

Initialization

1. Initialize Rooms: The initial_room() function initializes the details of 80 rooms, categorized into four standards.
2. Welcome Screen: The welcome() function prompts for user login. The correct username and password are "000" and "666666" respectively.

Main Functions

• Book Room: The book_room() function allows customers to book rooms by selecting the room standard and number of days.
• Check In: The check_in() function handles customer check-in, charging based on the selected room standard and number of days.
• Check Out: The check_out() function manages customer check-out, adjusting the bill based on actual stay duration.
• Inquiry: The inquire() function provides room status information and customer details.

Workflow

1. Start the program.
2. Login with the correct username and password.
3. Select the desired service from booking, check-in, check-out, or inquiry.
4. Follow the prompts to complete the selected service.
5. To continue using the system, press "1". To exit, press "2".
