This project implements a hotel reservation system in C++, providing functionalities for managing clients, reservations, room information, and account settings.

Features
Client Management:

Register new clients with their personal information.
Manage client accounts, including login and password management.
Reservation Management:

Reserve different types of rooms with specific dates.
View and manage reservations, including cancellation and modification.
Room Information:

Display detailed information about available room types and amenities.
Sort room types based on price from highest to lowest.
Account Settings:

Update user information such as password, email, and contact number.
Administrative Functions:

Admin login to access administrative functionalities.
View and manage all reservations and client accounts.
Algorithms and C++ Concepts Used
1. Algorithms
Sorting:
Implemented sorting algorithms to arrange room types by price in descending order (std::sort).
2. C++ Concepts
Classes and Objects:

Utilized classes (Account, HotelReservationSystem) to encapsulate data and operations related to clients, reservations, and system functionalities.
Implemented object-oriented principles for modularity and reusability.
Pointers and Dynamic Memory Allocation:

Managed dynamic memory allocation for storing reservations using linked list structures (Node).
File Handling:

Read and write operations for storing client credentials and reservation data using file streams (ifstream, ofstream).
String Manipulation:

Manipulated strings (std::string) for managing user inputs, passwords, and email addresses.
Control Structures:

Implemented control structures (if, switch, while, for) for flow control and decision making throughout the program.
Function Overloading and Encapsulation:

Overloaded functions within classes (Account) to handle different parameters and functionalities related to user account management.
Standard Template Library (STL):

Used STL containers (std::vector) for managing room availability and other dynamic data structures.
Example
cpp
Copy code
#include "HRS.hpp"
#include "ACCOUNT_HPP"
#include "Sorted_roomprice.hpp"
#include "RESERVATIONSYSTEM_HPP"
#include "ACCOUNT_SETTING_HPP"

int main() {
    // Initialize system and handle user interactions
    // Example: Add reservations, manage client accounts, etc.
    return 0;
}
Usage
Setup
Clone the repository to your local machine.
Compile the program using a C++ compiler (e.g., g++, Visual Studio).
Running the Program
Execute the compiled binary (e.g., ./hotel_reservation_system).
