Hotel Management in C++

Creating a hotel management system in C++ involves designing a program that can manage various aspects of a hotel, such as room booking, guest check-in/check-out, room availability, billing, and more. Below is a simplified example of a hotel management system in C++. Please note that this is a basic implementation and does not cover all the complexities that a real-world system would entail.

C++
#include <iostream>
#include <vector>
#include <string>

using namespace std;

// Define a class to represent a hotel room
class HotelRoom {
public:
    HotelRoom(int roomNumber, int capacity, double pricePerNight)
        : roomNumber(roomNumber), capacity(capacity), pricePerNight(pricePerNight), isOccupied(false) {}

    int getRoomNumber() const {
        return roomNumber;
    }

    int getCapacity() const {
        return capacity;
    }

    double getPricePerNight() const {
        return pricePerNight;
    }

    bool isOccupied() const {
        return isOccupied;
    }

    void occupyRoom() {
        isOccupied = true;
    }

    void vacateRoom() {
        isOccupied = false;
    }

private:
    int roomNumber;
    int capacity;
    double pricePerNight;
    bool isOccupied;
};

// Define a class to represent a hotel
class Hotel {
public:
    Hotel(const string& name) : name(name) {}

    // Add a room to the hotel
    void addRoom(int roomNumber, int capacity, double pricePerNight) {
        rooms.push_back(HotelRoom(roomNumber, capacity, pricePerNight));
    }

    // Display available rooms
    void displayAvailableRooms() {
        cout << "Available Rooms at " << name << ":" << endl;
        for (const HotelRoom& room : rooms) {
            if (!room.isOccupied()) {
                cout << "Room Number: " << room.getRoomNumber() << ", Capacity: " << room.getCapacity()
                     << ", Price per Night: $" << room.getPricePerNight() << endl;
            }
        }
    }

    // Book a room
    void bookRoom(int roomNumber) {
        for (HotelRoom& room : rooms) {
            if (room.getRoomNumber() == roomNumber && !room.isOccupied()) {
                room.occupyRoom();
                cout << "Room " << roomNumber << " has been booked." << endl;
                return;
            }
        }
        cout << "Room " << roomNumber << " is not available for booking." << endl;
    }

    // Check-out from a room
    void checkOut(int roomNumber) {
        for (HotelRoom& room : rooms) {
            if (room.getRoomNumber() == roomNumber && room.isOccupied()) {
                room.vacateRoom();
                cout << "Checked out from Room " << roomNumber << "." << endl;
                return;
            }
        }
        cout << "Room " << roomNumber << " is not occupied." << endl;
    }

private:
    string name;
    vector<HotelRoom> rooms;
};

int main() {
    Hotel myHotel("MyHotel");

    // Add rooms to the hotel
    myHotel.addRoom(101, 2, 100.0);
    myHotel.addRoom(102, 4, 200.0);
    myHotel.addRoom(103, 1, 50.0);

    // Display available rooms
    myHotel.displayAvailableRooms();

    // Book a room
    myHotel.bookRoom(102);

    // Display available rooms after booking
    myHotel.displayAvailableRooms();

    // Check-out from a room
    myHotel.checkOut(102);

    // Display available rooms after check-out
    myHotel.displayAvailableRooms();

    return 0;
}

This is a basic implementation to give you an idea of how a hotel management system in C++ could be structured. In a real-world scenario, you would likely need to include additional features like guest information, reservation management, billing, and more advanced error handling.
