本文实现一个酒店管理系统小程序，涉及多个方面，包括用户接口、房间管理、预订系统、用户管理等。为了保持示例的简洁性，下面的实现将包括一个简单的控制台程序，演示基本的酒店管理功能。这将涵盖以下功能：

1. 查看房间状态
2. 预订房间
3. 取消预订
4. 查看预订信息

以下是一个基础的实现示例：

1. 主要文件和目录结构

hotel_management/
├── main.cpp
├── Hotel.h
├── Hotel.cpp
├── Room.h
├── Room.cpp
└── CMakeLists.txt

2. Room.h

#ifndef ROOM_H
#define ROOM_H#include <string>class Room {
public:Room(int number, bool isAvailable = true);int getNumber() const;bool isAvailable() const;void book();void cancel();private:int number;bool available;
};#endif // ROOM_H

3. Room.cpp

#include "Room.h"Room::Room(int number, bool isAvailable) : number(number), available(isAvailable) {}int Room::getNumber() const {return number;
}bool Room::isAvailable() const {return available;
}void Room::book() {available = false;
}void Room::cancel() {available = true;
}

4. Hotel.h

#ifndef HOTEL_H
#define HOTEL_H#include "Room.h"
#include <vector>class Hotel {
public:Hotel(int numRooms);void showAvailableRooms() const;bool bookRoom(int roomNumber);bool cancelBooking(int roomNumber);void showBookings() const;private:std::vector<Room> rooms;
};#endif // HOTEL_H

5. Hotel.cpp

#include "Hotel.h"
#include <iostream>Hotel::Hotel(int numRooms) {for (int i = 1; i <= numRooms; ++i) {rooms.emplace_back(i);}
}void Hotel::showAvailableRooms() const {std::cout << "Available Rooms:\n";for (const auto &room : rooms) {if (room.isAvailable()) {std::cout << "Room " << room.getNumber() << "\n";}}
}bool Hotel::bookRoom(int roomNumber) {for (auto &room : rooms) {if (room.getNumber() == roomNumber && room.isAvailable()) {room.book();return true;}}return false;
}bool Hotel::cancelBooking(int roomNumber) {for (auto &room : rooms) {if (room.getNumber() == roomNumber && !room.isAvailable()) {room.cancel();return true;}}return false;
}void Hotel::showBookings() const {std::cout << "Booked Rooms:\n";for (const auto &room : rooms) {if (!room.isAvailable()) {std::cout << "Room " << room.getNumber() << "\n";}}
}

6. main.cpp

#include <iostream>
#include "Hotel.h"void showMenu() {std::cout << "Hotel Management System\n";std::cout << "1. View Available Rooms\n";std::cout << "2. Book a Room\n";std::cout << "3. Cancel Booking\n";std::cout << "4. View Bookings\n";std::cout << "5. Exit\n";std::cout << "Choose an option: ";
}int main() {Hotel hotel(10); // Initialize hotel with 10 roomsint choice;int roomNumber;while (true) {showMenu();std::cin >> choice;switch (choice) {case 1:hotel.showAvailableRooms();break;case 2:std::cout << "Enter room number to book: ";std::cin >> roomNumber;if (hotel.bookRoom(roomNumber)) {std::cout << "Room " << roomNumber << " booked successfully.\n";} else {std::cout << "Failed to book room " << roomNumber << ".\n";}break;case 3:std::cout << "Enter room number to cancel: ";std::cin >> roomNumber;if (hotel.cancelBooking(roomNumber)) {std::cout << "Booking for room " << roomNumber << " canceled successfully.\n";} else {std::cout << "Failed to cancel booking for room " << roomNumber << ".\n";}break;case 4:hotel.showBookings();break;case 5:return 0;default:std::cout << "Invalid option. Please try again.\n";}}return 0;
}

7. CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(HotelManagement)set(CMAKE_CXX_STANDARD 11)add_executable(HotelManagement main.cpp Hotel.cpp Room.cpp)

编译和运行

1. 创建构建目录:

   mkdir build
   cd build
   

2. 生成构建文件:

   cmake ..
   

3. 编译项目:

   make
   

4. 运行程序:

   ./HotelManagement
   

说明

• Room 类: 表示酒店房间，包含房间号和是否可用的状态。
• Hotel 类: 管理一组房间，提供查看可用房间、预订房间、取消预订和查看预订信息的功能。
• main.cpp: 提供了一个简单的用户界面，允许用户选择不同的操作并与 Hotel 类交互。

这个示例是一个简化的酒店管理系统，适合用作学习和基础参考。如果需要更复杂的功能，如用户身份管理、详细的预订信息管理等，可以在此基础上扩展。
