8.23 C++day3作业

1. 整理思维导图

 2、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
{
    string name;
    int age;
    int *height;
    int *weight;
public:
    //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;
    }
    Per()
    {
        cout << "Per无参构造函数" << endl;
    }
 
    //深拷贝构造函数
    Per(Per &other)
    {
        this->name = other.name;
        this->age = other.age;
        height = new int(*(other.height));
        weight = new int(*(other.weight));
        cout << "Per拷贝构造函数" << endl;
    }
 
    //析构函数
    ~Per()
    {
        delete height;
        delete weight;
        cout << "Per析构函数" << endl;
    }
 
    void set_msg(int height,int weight)
    {
        *(this->height) = height;
        *(this->weight) = weight;
    }
    void fun();
};
 
class Stu
{
    float score;
    Per p1;
public:
    //有参构造函数
    Stu(string name,int age,int height,int weight,float score):score(score),p1(name,age,height,weight)
    {

    //无参构造函数
    Stu()
