编程题

1.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 

using namespace std;
class Per
{
private:
    string name;
    int age;
    int *height;
    int *weight;
public:
    Per() {cout << "Per::无参构造函数" << endl;}
    Per(string name,int age,int height,int weight):name(name),age(age),height(new int(height)),weight(new int(weight))
    {
        cout << "Per::有参构造函数" << endl;
    }
    ~Per()
    {
        cout << "Per::析构函数" << endl;
        delete height;
        delete weight;
    }
    Per(const Per &other):name(other.name),age(other.age),height(other.height),weight(other.weight)
    {
        cout << "Per::拷贝构造函数" << endl;
    }
    void show()
    {
        cout << "姓名:" << name << endl << "年龄:" << age << endl << "身高:" << *(height) << endl << "体重:" << *(weight) << endl;
    }


};

class Stu
{
private:
    Per p1;
    double score;
public:
    Stu() {cout << "Stu::无参构造函数" << endl;}
    Stu(string name,int age,int height,int weight,double score):p1(name,age,height,weight),score(score)
    {
        cout << "Stu::有参构造函数" << endl;
    }
    ~Stu()
    {
        cout << "Stu::析构函数" << endl;
    }
    Stu(const Stu &other):p1(other.p1),score(other.score)
    {
        cout << "Stu::拷贝构造函数" << endl;
    }
    void show()
    {
        p1.show();
        cout << "成绩:" << score << endl;
    }

};
int main()
{
    Stu s1("张三",19,175,135,88);
    s1.show();
    return 0;
}
