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 //封装Per类
{
private:  //私有
    string name; //名字
    int age;     //年龄
    int *height; //身高
    int *weight; //体重
public:   //公有
    Per() {cout << "Per::无参构造函数" << endl;}
    //初始化
    Per(string name,int age,int h,int w):name(name),age(age),height(new int(h)),weight(new int(w))
    {
        cout << "Per::有参构造函数" << endl;
    }
    ~Per()
    {
        cout << "Per::析构函数" << endl;
        delete height;
        delete weight;
    }
    void show()
    {
        cout << "姓名=" << name << endl;
        cout << "年龄=" << age << endl;
        cout << "身高=" << *height << endl;
        cout << "体重=" << *weight << endl;
    }
};
class Stu  //封装Stu类
{
private:   //私有
    double score; //成绩
    Per p1;
public:
    Stu() {cout << "Stu::无参构造函数" << endl;}
    Stu(double s,string name,int age,int height,int weight):score(s),p1(name,age,height,weight)
    {
        cout << "Stu::有参构造函数" << endl;
    }
    ~Stu()
    {
        cout << "Stu::析构函数" << endl;
    }
    Stu(const Stu &other):score(other.score),p1(other.p1)
    {
        cout << "Stu::拷贝构造函数" << endl;
    }
    void show()
    {
        p1.show();
        cout << "成绩=" << score << endl;
