1. 设计一个Per类，类中包含私有成员：姓名、年龄、指针成员身高、体重，再设计一个Stu类，类中包含私有成员：成绩、Per类对象 p1，设计这两个类的构造函数、析构函数和拷贝构造函数。

#include <iostream>

using namespace std;
class Per
{
    string name;
    int age;
    int *hight;
    int *weight;
public:
    void my_set(string name,int age)
    {
        this-> name = name;
        this-> age = age;
    }
    void show()
    {
        cout <<"名字为:" << name << ' ' << "成绩为:" << age << ' ';
        cout << "身高为:" << *hight << ' ' << "体重为:" << *weight << endl;
    }
    Per(int *h,int *w):hight(new int),weight(new int)
    {
        hight=h;
        weight=w;
        cout << "这是Per的构造函数" << endl;
    }
    Per(Per &other)
    {
        int *hi=new int;
        int *we=new int;
        *hi = *(other.hight);
        *we = *(other.weight);
        cout << "这是Per的拷贝构造函数" << endl;
    }
    ~Per()
    {
        cout << "这是Per的解析函数" << endl;
        delete hight;
        delete weight;
        hight = nullptr;
        weight = nullptr;
    }
};

class Stu
{
    int score;
public:
    Per p1;
    void set_stu(int score)
    {
       this->score=score;
    }
    void show()
    {
        cout << "成绩为:" << score << endl;
    }
    Stu(int *hight,int *weight):p1(hight,weight)
    {
        cout << "这是Stu的构造函数" << endl;
    }
    Stu(Stu &other):p1(other.p1)
    {
        this ->score = other.score;
        p1=other.p1;
        cout << "这是Stu的拷贝构造函数" << endl;
    }
    ~Stu()
    {
        cout << "这是Stu的解析函数" <<endl;
        p1.~Per();
    }

};

int main()
{
    int *hight=new int;
    *hight = 183;
    int *weight=new int;
    *weight = 120;
    Stu s1(hight,weight);
    s1.p1.my_set("张三",18);
    s1.p1.show();
    s1.set_stu(89);
    s1.show();
    *hight = 180;
    *weight = 110;
    Stu s2(hight,weight);
    s2.p1.my_set("李四",20);
    s2.p1.show();
    s2.set_stu(90);
    s2.show();

    return 0;
