怎么用C++写一个健身房管理系统

一个简单的健身房管理系统可能需要以下功能：

1. 会员信息管理：包括会员姓名、性别、年龄、电话、会员卡号、会员类型等信息；
2. 器材管理：包括器材名称、型号、数量、使用状态等信息；
3. 健身房员工管理：包括员工姓名、职位、联系方式等信息；
4. 会员和员工的登录和注册功能；
5. 会员和员工的权限管理；
6. 销售管理：包括会员卡的销售、续费等功能；
7. 消费管理：记录会员的消费记录；
8. 财务统计：统计健身房的收入和支出情况。

以下是一个简单的健身房管理系统的代码示例：

#include <iostream>
#include <string>
#include <vector>

using namespace std;

// 声明会员结构体
struct Member {
    string name;
    string gender;
    int age;
    string phone;
    int id;
    string type;
};

// 声明器材结构体
struct Equipment {
    string name;
    string model;
    int quantity;
    bool in_use;
};

// 声明员工结构体
struct Employee {
    string name;
    string position;
    string phone;
};

// 声明会员卡结构体
struct Membership {
    int id;
    string type;
    int price;
};

// 声明消费记录结构体
struct Consumption {
    int member_id;
    string date;
    int amount;
};

// 声明健身房类
class Gym {
public:
    // 构造函数
    Gym() {}

    // 添加会员信息
    void add_member(string name, string gender, int age, string phone, int id, string type) {
