你作为一个资深的VS2022使用者需要用c++类和对象、构造函数、对象数组、类的组合、运算符重载、虚函数、派生类、文件操作等写一个简短易懂的代码 1.问题描述 统计某公司人员信息包括编号、姓名、性别、电话号码、学历、工资，设计一个程序灵活的实现各种功能。2.功能要求 （1）添加功能 （2）查询功能 （3）显示功能 （4）编辑功能 （5）删除功能 （6）排序功能 （7）保存功能 （8）读取功能 我需要你保持代码可以在VS2022上正常运行

好的，可以参考下面的代码实现：

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
#include <algorithm>

using namespace std;

// 定义员工类
class Employee {
public:
    int id; // 员工编号
    string name; // 员工姓名
    char gender; // 员工性别
    string phone; // 员工电话号码
    string education; // 员工学历
    double salary; // 员工工资

    // 构造函数
    Employee() {}
    Employee(int id, string name, char gender, string phone, string education, double salary) :
        id(id), name(name), gender(gender), phone(phone), education(education), salary(salary) {}

    // 打印员工信息
    void print() {
        cout << "编号：" << id << "，姓名：" << name << "，性别：" << gender << "，电话号码：" << phone
            << "，学历：" << education << "，工资：" << salary << endl;
    }

    // 重载小于运算符，用于排序
    bool operator< (const Employee& e) const {
        return id < e.id;
    }
};

// 定义员工管理类
class EmployeeManager {
private:
    vector<Employee> employees; // 员工列表

public:

    void addEmployee() {

在 VS2022 上运行时，需要注意：

1. 需要将文件后缀名改为 .cpp；
2. 可以选择使用 Visual C++ 2019 或者 Visual C++ 2022 编译器编译；
3. 测试时可以将员工信息保存到 employees.txt 文件中，读取时也需要使用该文件。
