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;float *height;float *weight;
public:Per(){cout << "Per的无参构造函数" << endl;}Per(string name,int age,float *height,float *weight){this->name = name;this->age= age;this->height = height;this->weight = weight;cout << "Per的有参构造函数" << endl;}Per(Per &other){this->name = other.name;this->age= other.age;height = new float;weight = new float;*height = *(other.height);*weight = *(other.weight);cout << "Per的深拷贝构造函数" << endl;}void set_h(float a){*height = a;}void set_w(float b){*weight = b;}~Per(){cout << "准备释放堆区空间" << endl;delete height;delete weight;height = nullptr;weight = nullptr;cout << "Per的析构函数" << endl;}void show(){cout << "姓名:" << name << endl;cout << "年龄:" << age << endl;cout << "身高:" << *height << endl;cout << "体重:" << *weight << endl;}
};
class Stu{int score;
public:Per p1;
public:Stu(int score,string name,int age,float *height,float *weight):score(score),p1{name,age,height,weight}{cout << "Stu的有参构造函数" << endl;}Stu(){cout << "Stu的无参构造函数" << endl;}void show(){cout << "Stu中的成绩=" << score << endl;}
};
int main()
{float *height = new float;*height = 188.2;float *weight = new float;*weight = 75.5;Stu s1(99,"亚索",25,height,weight);Stu s2=s1;cout << "s1中的个人信息" << endl;s1.show();s1.p1.show();cout << "s2中的个人信息" << endl;s2.show();s2.p1.show();cout << "s2修改后中的个人信息" << endl;s2.p1.set_h(180.5);s2.p1.set_w(80.5);s2.show();s2.p1.show();return 0;
