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**。

#include <iostream>

using namespace std;
class Stu{
private:
    double score;
public:
    Stu(){cout << "Stu 无参构造函数" << endl;}
    Stu(double score):score(score){
        cout << "Stu 有参构造函数" << endl;
    }
    void shor(){
        cout << "成绩" << score << endl;
    }
};
class Per{
private:
    string name;
    int age;
    double *stature;
    double *weight;
    Stu p1;
public:
    Per(){cout << "Per 无参构造函数" << endl;}
    Per(string name, int age, double stature, double weight, double score):name(name), age(age), stature(new double(stature)), weight(new double(weight)), p1(score)
    {
        cout << "Stu 有参构造函数" << endl;
    }
    void show(){
        cout << "姓名=" << name << " " << "年龄=" << age << " " << "身高=" << *stature << " " << "体重=" << *weight << endl;
        p1.shor();
    }
    ~Per(){
        delete stature;
        stature = nullptr;
        delete weight;
        weight = nullptr;
    }
};
int main()
{
    Per s1;
    Per s2("王五",32,170,160,99);
    s2.show();
    return 0;
}
