作业：
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;struct Per
{
private:string name;int age;double *height;double *weight;
public:Per(string name,int age,double height,double weight):name(name),age(age),height(new double(height)),weight(new double(weight)){cout << "Per::构造函数" << endl;}Per(const Per &Per1):name(Per1.name),age(Per1.age),height(new double(*(Per1.height))),weight(new double(*(Per1.weight))){cout << "Per::拷贝构造函数" << endl;}~Per(){delete height;delete weight;cout << "Per::析构函数" << endl;}
};struct Stu
{
private:double score;Per p1;
public:Stu(double score,string name,int age,double height,double weight):score(score),p1(name,age,height,weight){cout <<  "Stu::构造函数" << endl;}Stu(const Stu &Stu1):score(Stu1.score),p1(Stu1.p1){cout << "Stu::拷贝构造函数" << endl;}~Stu(){cout << "Stu::析构函数" << endl;}
};int main()
{Stu s1(99,"小明",20,144,178);Stu s2(s1);Per p2("小红",19,120,166);Per p3(p2);return 0;
}
