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
{
private:
    string name;
    int age;
    int *height;
    int *weight;
public:
    Per(){cout << "Per::无参构造函数" << endl;}

    Per(string name, int age, int height, int weight):name(name),age(age),height(new int(height)),weight(new int(weight))
    {
        cout << "Per::有参构造函数" << endl;
    }

    Per(const Per &other):name(other.name),age(other.age),height(new int(*(other.height))),weight(new int(*(other.weight)))
    {
        cout << "Per::拷贝构造函数" << endl;
    }

    ~Per()
    {
        delete height;
        delete weight;
        cout << "Per::析构函数" << endl;
    }

    void show()
    {
        cout << "姓名: " << name << endl;
        cout << "年龄: " << age << endl;
        cout << "身高: " << height << endl;
        cout << "体重: " << weight << endl;
    }

};

class Stu
{
private:
    double score;
    Per p1;
public:
    Stu(){cout << "Stu::无参构造函数" << endl;}

    Stu(double score, string name, int age, int height, int weight):score(score),p1(name,age,height,weight)
    {
        cout << "Stu::有参构造函数" << endl;

    Stu(const Stu &other):score(other.score),p1(other.p1){

    }

    ~Stu()

        cout << "Stu::析构函数" << endl;
    }

    void show()
    {
        cout << "分数: " << score << endl;
        p1.show();
    }
};
int main()

    Stu s1(99, "大帅比", 20, 185, 145);
    s1.show();
    Stu s2(s1);
    s2.show();

    Per p3("帅比", 20, 188, 160);
    p3.show();
    Per p4(p3);
    p4.show();

    return 0;
