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
{
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;
    }
};
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)
    {
        cout << "Stu::拷贝构造函数" << endl;
    }
    ~Stu()
    {
        cout << "Stu::析构函数" << endl;
    }
};

int main()
{
    Per per;
    Per per2("张三",19,180,75);
    Per per3(per2);

    Stu stu;
    Stu stu2(89,"李四",20,175,140);
    Stu stu3(stu2);
    return 0;
}
