某公司有两类职员Employee和Manager，Manager是一种特殊的Employee。每个Employee对象所具有的基本信息为：姓名、年龄、工作年限、部门号；Manager对象除具有上述基本信息外，还具有级别(level)信息。公司中的Employee和Manager都具有以下两种基本操作，请根据上述描述，用C++语言定义并实现类Employee和Manager。 a．insert Info（）//实现对象信息的输入 b．printOn() // 输出对象的基本信息（姓名、年龄、工作年限、部门号、在职情况） c. retire() // 判断是否到了退休年龄，是，表明在职情况为退休。公司规定： // Employee类对象的退休年龄为55岁，Manager类对象的退休年龄为60岁 编程要求： 1、定义并实现类Employee和Manager 2、按照年龄降序模式分别输出公司中两类人员的人员情况（注意：Manager对象也是Employee对象）。 注

以下是C++语言的实现：

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

class Employee {
protected:
    string name;  // 姓名
    int age;  // 年龄
    int years;  // 工作年限
    int department;  // 部门号
    bool isRetired;  // 是否退休

public:
    Employee(string name, int age, int years, int department) {
        this->name = name;
        this->age = age;
        this->years = years;
        this->department = department;
        this->isRetired = false;
    }

    virtual void insertInfo() {
        cout << "请输入姓名：";
        cin >> name;
        cout << "请输入年龄：";
        cin >> age;
        cout << "请输入工作年限：";
        cin >> years;
        cout << "请输入部门号：";
        cin >> department;
    }

    virtual void printOn() {
        cout << "姓名：" << name << endl;
        cout << "年龄：" << age << endl;
        cout << "工作年限：" << years << endl;
        cout << "部门号：" << department << endl;
        cout << "在职情况：" << (isRetired ? "退休" : "在职") << endl;
    }

    virtual void retire() {
        if (age >= 55) {
            isRetired = true;
        }
    }
};

class Manager : public Employee {
private:
    int level;  // 级别

public:
    Manager(string name, int age, int years, int department, int level) : Employee(name, age, years, department) {
        this->level = level;
    }

    void insertInfo() {
        Employee::insertInfo();
        cout << "请输入级别：";
        cin >> level;
    }

    void printOn() {
        Employee::printOn();
        cout << "级别：" << level << endl;
    }

    void retire() {
        if (age >= 60) {
            isRetired = true;
        }
    }
};

int main() {
    const int MAX_EMPLOYEES = 100;  // 最大员工数
    Employee* employees[MAX_EMPLOYEES];  // 员工数组
    int numEmployees = 0;  // 员工数

    // 输入Employee和Manager对象信息
    cout << "请输入员工数：";
    cin >> numEmployees;
    for (int i = 0; i < numEmployees; i++) {
        int type;
        cout << "请输入员工类型（1：普通员工；2：经理）：";
        cin >> type;

        string name;
        int age, years, department, level;
        cout << "请输入姓名：";
        cin >> name;
        cout << "请输入年龄：";
        cin >> age;
        cout << "请输入工作年限：";
        cin >> years;
        cout << "请输入部门号：";
        cin >> department;

        if (type == 2) {
            cout << "请输入级别：";
            cin >> level;
            employees[i] = new Manager(name, age, years, department, level);
        } else {
            employees[i] = new Employee(name, age, years, department);
        }
    }

    // 判断是否退休并输出信息
    for (int i = 0; i < numEmployees; i++) {
        employees[i]->retire();
    }

    // 按照年龄降序输出信息
    for (int i = 0; i < numEmployees - 1; i++) {
        for (int j = i + 1; j < numEmployees; j++) {
            if (employees[i]->age < employees[j]->age) {
                Employee* temp = employees[i];
                employees[i] = employees[j];
                employees[j] = temp;
            }
        }
    }

    cout << "按照年龄降序输出员工信息：" << endl;
    for (int i = 0; i < numEmployees; i++) {
        employees[i]->printOn();
        cout << endl;
    }

    // 释放内存
    for (int i = 0; i < numEmployees; i++) {
        delete employees[i];
    }

    return 0;
}

实现了Employee类和Manager类，其中Manager类继承自Employee类，重写了retire()方法。在main函数中，先输入员工信息，然后判断是否退休并输出信息，最后按照年龄降序输出员工信息。
