Person类的结构如图所示，包含姓名，身份证号，性别，年龄四个成员数据，以及构造函数，析构函数，显示信息函数。 要求在此基础上派生出Employee类，该类新增两个数据成员，分别为部门和薪水，Employee包含构造函数，析构函数，显示函数。 请1）完成Person类的各成员函数，2）完成Employee类的定义以及Employee各成员函数的定义。 class Person{ protected: char *name; char *id; int sex; ///0:女,1:男 int age; public: Person(char *p_name,char *p_id,int p_sex,int p_age); void show(); ~Person(); };

1）完成Person类的各成员函数：

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

class Person{
protected:
    char *name;
    char *id;
    int sex;     // 0:女,1:男
    int age;
public:
    Person(char *p_name,char *p_id,int p_sex,int p_age){
        name = new char[strlen(p_name)+1];
        strcpy(name, p_name);
        id = new char[strlen(p_id)+1];
        strcpy(id, p_id);
        sex = p_sex;
        age = p_age;
    }
    void show(){
        cout<<"姓名:"<<name<<endl;
        cout<<"身份证号:"<<id<<endl;
        cout<<"性别:"<< (sex==1?"男":"女") <<endl;
        cout<<"年龄:"<<age<<endl;
    }
    ~Person(){
        delete[] name;
        delete[] id;
    }
};

2）完成Employee类的定义以及Employee各成员函数的定义：

class Employee: public Person{
private:
    char *department;
    int salary;
public:
    Employee(char *p_name,char *p_id,int p_sex,int p_age, char *p_department, int p_salary)
        :Person(p_name, p_id, p_sex, p_age){
            department = new char[strlen(p_department)+1];
            strcpy(department, p_department);
            salary = p_salary;
    }
    void show(){
        Person::show();
        cout<<"部门:"<<department<<endl;
        cout<<"薪水:"<<salary<<endl;
    }
    ~Employee(){
        delete[] department;
    }
};
