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。

代码:

#include <iostream>

using namespace std;

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

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

int main()
{
    Per p;
    Per p1("zzh",18,180,70);
    Per p2(p1);

    Stu s;
    Stu s1(99.9,"zzh",18,180,70);
    Stu s2(s1);
    s1.show();
    return 0;
}

结果：
