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。

代码：

#include <iostream>using namespace std;class Per
{
private:string name;int age;double *hight;double *weight;
public:Per(){cout << "Per::无参构造函数" << endl;}Per(string name,int age,double h,double w):name(name),age(age),hight(new double(h)),weight(new double(w)){cout << "Per::有参构造函数" << endl;cout << name << " " << age << " " << *hight <<" " << *weight << endl;}~Per(){delete (hight);delete (weight);hight = nullptr;weight = nullptr;cout << "Per::析构函数" << endl;}Per(const Per &other):name(other.name),age(other.age),hight(new double(*(other.hight))),weight(new double(*(other.weight))){cout << "Per::拷贝构造函数" << endl;cout << name << " " << age << " " << *hight <<" " << *weight << endl;}void show(){cout << name << " " << age << " " << *hight <<" " << *weight << " ";}};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 hight, double weight):score(score),p1(name,age,hight,weight){cout << "Stu::有参构造函数" << endl;p1.show();cout << score << 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;p1.show();cout << score << endl;}};int main()
{cout << "请输入姓名、年龄、身高、体重、成绩：" << endl;string name;int age;double hight,weight,score;cin >> name >> age >> hight >> weight >> score;Stu s1(score,name,age,hight,weight);cout << "__________________________________" << endl;cout << "请输入姓名、年龄、身高、体重、成绩：" << endl;cin >> name >> age >> hight >> weight;Per p1(name,age,hight,weight);cout << "__________________________________" << endl;Stu s2(s1);cout << "__________________________________" << endl;Per p2(p1);return 0;
}
