使用類的嵌套，并自定義析構函數

#include <iostream>using namespace std;
class Per{
private:string name;int age;double hight;double weight;
public:Per(string name,int age,double hight,double weight):name(name),age(age),hight(hight),weight(weight){cout << "Per初始化完成" << endl;}~Per(){cout <<"Per析構函數" << this << endl;}void dipaly();
};
class Stu{
private:double score;Per* p1;
public:Stu(double score,Per p1):score(score),p1(new Per(p1)){cout << "Stu初始化完成" << endl;}~Stu(){cout << "Stu析構函數" << this << endl;delete p1;p1=nullptr;}void show();
};
void Stu::show(){cout <<"score:" << score << endl;cout << "&p1=" << p1 <<endl;
}
void Per::dipaly(){cout << "name:" << name << "    age:" << age << "   hight:" << hight << "   weight:" << weight << endl;
}
int main()
{Per p("Tom",24,197.7,70.4);Stu S(99.9,p);cout << "&p=" << &p <<"  &S=" << &S <<endl;p.dipaly();S.show();return 0;
}
