## Overview

This is a small, authority-only hotel management console implemented in one C++ source file. An administrator logs in, then uses a menu for room maintenance, bookings and queries. Bookings record customer details and update room availability; cancellation resets availability. The program persists records in text files. The excerpt confirms login and several file operations, but omits most of the menu switch, so feature-dispatch links are marked unverified rather than assumed.

Main entry points: [`Full final project.cpp`](https://github.com/fahim-5305/hotel-management-system/blob/main/Full%20final%20project.cpp) (Main menu)
