C++构造函数，析构函数，拷贝构造函数

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;

    string name;
    int age;
    int *high;
    int *wigth;

    Per(string name, int age, int high, int wigth):name(name), age(age), high(new int), wigth(new int)
    {
        cout << "Per 有参构造函数" <<endl;
    }

class Stu

    cout << "score= " <<score <<endl;

int main()
