设计一个用于人事管理的(人员)类。考虑到通用性，这里只抽象出所有类型人员都具有的属性：编号、性别、姓名、出生日期、身份证号等。其中“出生日期”声明为一个“日期”类内嵌子对象。用成员函数实现对人员信息的录入和显示。要求包括：构造函数和析构函数、复制构造函数、内联成员函数、带默认形参值得成员函数，类的组合。并写一个与之相匹配的main主函数

下面是一个用于人事管理的人员类的代码实现：

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

// 日期类
class Date {
public:
    Date(int year = 1970, int month = 1, int day = 1) {
        m_year = year;
        m_month = month;
        m_day = day;
    }
    int getYear() const {
        return m_year;
    }
    int getMonth() const {
        return m_month;
    }
    int getDay() const {
        return m_day;
    }
private:
    int m_year;
    int m_month;
    int m_day;
};

// 人员类
class Person {
public:
    Person(int id = 0, string name = "", char gender = 'M', Date birthDate = Date(), string idNumber = "") {
        m_id = id;
        m_name = name;
        m_gender = gender;
        m_birthDate = birthDate;
        m_idNumber = idNumber;
    }
    Person(const Person& other) {
        m_id = other.m_id;
        m_name = other.m_name;
        m_gender = other.m_gender;
        m_birthDate = other.m_birthDate;
        m_idNumber = other.m_idNumber;
    }
    ~Person() {}
    inline int getId() const {
        return m_id;
    }
    inline string getName() const {
        return m_name;
    }
    inline char getGender() const {
        return m_gender;
    }
    inline Date getBirthDate() const {
        return m_birthDate;
    }
    inline string getIdNumber() const {
        return m_idNumber;
    }
    void setId(int id) {
        m_id = id;
    }
    void setName(string name) {
        m_name = name;
    }
    void setGender(char gender) {
        m_gender = gender;
    }
    void setBirthDate(Date birthDate) {
        m_birthDate = birthDate;
    }
    void setIdNumber(string idNumber) {
        m_idNumber = idNumber;
    }
    void display() const {
        cout << "编号：" << m_id << endl;
        cout << "姓名：" << m_name << endl;
        cout << "性别：" << m_gender << endl;
        cout << "出生日期：" << m_birthDate.getYear() << "/" << m_birthDate.getMonth() << "/" << m_birthDate.getDay() << endl;
        cout << "身份证号：" << m_idNumber << endl;
    }
private:
    int m_id;
    string m_name;
    char m_gender;
    Date m_birthDate;
    string m_idNumber;
};

int main() {
    Date d(1990, 12, 31);
    Person p1(1001, "张三", 'M', d, "11010119901231001X");
    Person p2(p1);
    p2.setId(1002);
    p2.setName("李四");
    p2.setGender('F');
    p2.setBirthDate(Date(1995, 8, 15));
    p2.setIdNumber("11010119950815002X");
    p1.display();
    cout << endl;
    p2.display();
    return 0;
}

输出结果为：

编号：1001
姓名：张三
性别：M
出生日期：1990/12/31
身份证号：11010119901231001X

编号：1002
姓名：李四
性别：F
出生日期：1995/8/15
身份证号：11010119950815002X
