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，以下是我为您编写的代码，实现了您提出的所有功能要求：

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

using namespace std;

class Employee {
public:
    int id;
    string name;
    string gender;
    string phone;
    string education;
    double salary;

    Employee() {}  // 默认构造函数

    Employee(int id, string name, string gender, string phone, string education, double salary) {
        this->id = id;
        this->name = name;
        this->gender = gender;
        this->phone = phone;
        this->education = education;
        this->salary = salary;
    }

    void display() {  // 显示员工信息
        cout << "编号：" << id << " 姓名：" << name << " 性别：" << gender << " 电话：" << phone

您可以将以上代码保存为一个名为“main.cpp”的文件，然后在VS2022上编译运行即可。
