本文实例为大家分享了C++实现酒店管理系统的具体代码，供大家参考，具体内容如下
一、先看效果
1、run
2、查询
3、入住
再查询，可以看到201有人入住了
4、 退房
二、安装C++环境
Visual Studio2019安装与使用步骤
1、下载vs2019
访问：网站
2、点击免费下载： （community版本）
3、安装
选择通用windows平台开发
这个根据个人电脑的性能不同可以消耗的时间也不同，我的电脑大概需要1个小时所有，在安装的过程中是需要全程联网的，安装结束后，会提示重启电脑，然后我们点击“立刻重启”。
安装完成：
三、新建工程文件
1、文件——新建——项目
选择控制台程序
把代码复制到cpp文件
// ConsoleApplication1.cpp : 此文件包含 "main" 函数。程序执行将在此处开始并结束。// #include <iostream>#include <string.h>#include <stdlib.h>void enter();void check_in();void inquire();void check_out();void initial_room();using namespace std;int i = 0;struct Room{ int number; int floor; int state;};class Customer{ char name[10], ID[19]; int room_number; int change;public: Customer() { cout << "请您输入顾客的姓名\n"; cin >> name; cout << "请您输入顾客的身份证号码\n"; cin >> ID; change = 0; } void set_name(char* _name) { strcpy_s(name, _name); } void set_ID(char* _ID) { strcpy_s(ID, _ID); } void set_room_number(int n) { room_number = n; } char* get_name() { return name; } char* get_ID() { return ID; } int get_room_number() { return room_number; } ~Customer() { cout << "该顾客退房成功!" << endl; }};Room room[80];Customer* customer[80];int main(){ char choice = '1'; initial_room(); while (choice == '1') { enter(); cout << endl; cout << "继续使用本系统请按\"1\",退出请按\"2\"!

点击本地调试器
大功告成
