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;
    double *high;
    double weight;
public:
    Per()
    {
        cout << "Per::无参构造函数" << endl;
    }
    Per(string name,int age,double high,double weight):name(name),age(age),high(new double(high)),weight(weight)
    {
        cout << "Per::有参构造函数" << endl;
    }
    Per(const Per &other):name(other.name),age(other.age),high(new double(*(other.high))),weight(other.weight)
    {
        cout << "Per::拷贝构造函数" << endl;
    }
    ~Per()
    {
        cout << "Per::析构函数" << endl;
    }
    void show()
    {
        cout << "name:" << name << endl;
        cout << "age:"  << age  << endl;
        cout << "high:" << *high << endl;
        cout << "weight:" << weight << endl;
        delete high;
    }
};

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,double high,double weight):score(score),p1(name,age,high,weight)
    {
        cout << "Stu::有参构造函数" << endl;
    }
    Stu(const Stu &other):score(other.score),p1(other.p1)
    {
        cout << "Stu::拷贝构造函数" << endl;
    }
    ~Stu()
    {
        cout << "Stu::析构函数" << endl;
    }
    void show()
    {
        cout << "score:" << score << endl;
        p1.show();
    }
};



int main()
{
    Stu s1(92.5,"jack",19,188.5,55.2);
    s1.show();
    Stu s2(s1);
    s2.show();
    return 0;
}

运行结果
