用c++编写一个酒店客房管理系统

这里给出一个简单的酒店客房管理系统的实现，包括客房信息的录入、查询、修改和删除功能。

#include <iostream>
#include <vector>
#include <fstream>
#include <string>
using namespace std;

struct Room {
    int id; // 客房号码
    string type; // 房型
    int price; // 价格
    bool status; // 房间状态：true-已预订，false-未预订
};

vector<Room> rooms; // 客房信息存储

// 读取客房信息
void readRooms() {
    ifstream fin("rooms.txt");
    if (!fin) {
        cout << "文件打开失败！" << endl;
        return;
    }
    while (!fin.eof()) {
        Room room;
        fin >> room.id >> room.type >> room.price >> room.status;
        if (fin.fail()) {
            break;
        }
        rooms.push_back(room);
    }
    fin.close();
}

// 显示所有客房信息
void showRooms() {
    cout << "客房信息如下：" << endl;
    for (int i = 0; i < rooms.size(); i++) {
        cout << rooms[i].id << "\t" << rooms[i].type << "\t" << rooms[i].price << "\t";
        if (rooms[i].status) {
            cout << "已预订" << endl;
        } else {
            cout << "未预订" << endl;
        }
    }
}

// 添加客房信息
void addRoom() {
    Room room;
    cout << "请输入客房号码：";
    cin >> room.id;
    cout << "请输入房型：";
    cin >> room.type;
    cout << "请输入价格：";
    cin >> room.price;
    room.status = false;
    rooms.push_back(room);
    cout << "客房信息添加成功！" << endl;
}

// 查询客房信息
void searchRoom() {
    int id;
    cout << "请输入要查询的客房号码：";
    cin >> id;
    for (int i = 0; i < rooms.size(); i++) {
        if (rooms[i].id == id) {
            cout << rooms[i].id << "\t" << rooms[i].type << "\t" << rooms[i].price << "\t";
            if (rooms[i].status) {
                cout << "已预订" << endl;
            } else {
                cout << "未预订" << endl;
            }
            return;
        }
    }
    cout << "未找到指定客房！" << endl;
}

// 修改客房信息
void modifyRoom() {
    int id;
    cout << "请输入要修改的客房号码：";
    cin >> id;
    for (int i = 0; i < rooms.size(); i++) {
        if (rooms[i].id == id) {
            cout << "请输入新的房型：";
            cin >> rooms[i].type;
            cout << "请输入新的价格：";
            cin >> rooms[i].price;
            cout << "客房信息修改成功！" << endl;
            return;
        }
    }
    cout << "未找到指定客房！" << endl;
}

// 删除客房信息
void deleteRoom() {
    int id;
    cout << "请输入要删除的客房号码：";
    cin >> id;
    for (int i = 0; i < rooms.size(); i++) {
        if (rooms[i].id == id) {
            rooms.erase(rooms.begin() + i);
            cout << "客房信息删除成功！" << endl;
            return;
        }
    }
    cout << "未找到指定客房！" << endl;
}

// 保存客房信息
void saveRooms() {
    ofstream fout("rooms.txt");
    if (!fout) {
        cout << "文件打开失败！" << endl;
        return;
    }
    for (int i = 0; i < rooms.size(); i++) {
        fout << rooms[i].id << "\t" << rooms[i].type << "\t" << rooms[i].price << "\t" << rooms[i].status << endl;
    }
    fout.close();
}

int main() {
    readRooms();
    int choice;
    while (true) {
        cout << "请选择要进行的操作：" << endl;
        cout << "1. 显示所有客房信息" << endl;
        cout << "2. 添加客房信息" << endl;
        cout << "3. 查询客房信息" << endl;
        cout << "4. 修改客房信息" << endl;
        cout << "5. 删除客房信息" << endl;
        cout << "6. 退出系统" << endl;
        cin >> choice;
        switch (choice) {
            case 1:
                showRooms();
                break;
            case 2:
                addRoom();
                break;
            case 3:
                searchRoom();
                break;
            case 4:
                modifyRoom();
                break;
            case 5:
                deleteRoom();
                break;
            case 6:
                saveRooms();
                return 0;
            default:
                cout << "输入有误，请重新输入！" << endl;
                break;
        }
    }
    return 0;
}

客房信息保存在文本文件 "rooms.txt" 中，每行包含客房号码、房型、价格和状态。客房信息的读取和保存使用了文件输入输出流。客房信息存储使用了 vector 容器。客房状态采用了布尔类型，true 表示已预订，false 表示未预订。客房管理系统提供了添加、查询、修改和删除客房信息的功能。
