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;
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
{

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)
{
cout << "Stu有参构造函数" << endl;
}
//无参构造函数
Stu()
{
cout << "Stu无参构造函数" << endl;
}
//深拷贝构造函数
Stu(Stu &other)
{

//析构函数
