Living Eco Hotel Management System:

Project Overview:

Living Eco Hotel Management System is a console-based C program designed to streamline hotel room management. The system enables staff or admin to perform essential operations such as room booking, check-in/check-out, booking cancellation, stay extension/reduction, and viewing room statuses. Secure login for staff/admin users is supported, ensuring only authorized personnel can access management features.

Features:

• Room Booking: Reserve rooms for customers, including locals and foreigners, by selecting available rooms and entering their details. Supports bookings for future dates and enforces guest capacity per room.

• Check-in/Check-out: Verify customer details and process room check-ins/check-outs, including displaying stay bills and payment collection.

• Booking Management: Cancel bookings, extend or reduce stay duration, and show a list of current bookings with customer information.

• Room Status Overview: Display all rooms with their status (Available, Booked, Reserved), rent, maximum capacity, AC status, and booking dates.

• Secure Staff/Admin Login: Access management console via secure credentials to protect sensitive booking operations.

Program Structure:

• Data Model:

  • Each hotel room is represented by a Room struct, with fields for booking status, customer details, room information, and linked list navigation.

• Core Functions:

  • bookRoom(), cancelRoom(), checkInRoom(), checkout(), showRooms(), showBookings(), extendorreduceStay()

• Input Validation:

  • Ensures valid phone and NID/passport details, room numbers, date selection.

• Date Management:

  • Uses struct tm for managing booking and check-in dates, supporting future-dated bookings and preventing past date bookings.

• Payment Options:

  • Allows for bill payment through cash, card, or bank transfer, including discount options applied at checkout.

Usage:

1. Compile the Program

2. gcc -o hotel_management hotel_management.c

3. Note: The program uses <conio.h> for password entry. This header is available on Windows systems.

4. Run the Program

5. ./hotel_management

6. Login:

   • Enter Staff or Admin ID (pre-set IDs: 0, faisal2775, raha545)

   • Enter Password (pre-set passwords: 0, 01882740912, islam)

7. Menu Options:

   • Show All Rooms

   • Book Room

   • Check Out

   • View Bookings

   • Extend or Reduce Stay

   • Cancel Booking

Code Highlights:

• Implements a linked list for dynamic room management.

• Prevents double bookings and enforces logical date rules.

• Comprehensive input validation for critical data (phones, NIDs, dates).

• Basic billing and discount mechanism included.

Limitations & Notes:

• The program is console-based and intended for demonstration or small-scale hotel usage.

• Designed for Windows due to reliance on <conio.h> for hidden password input; portability may require code adjustment.

• All data exists only in memory for the duration of program execution—data persistence is not implemented.

• Only supports up to 30 rooms, configured by three blocks of 10 rooms each (room numbers: 101-110, 201-210, 301-310).
