思维导图

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
{
private:string name;int age;double *hight;double *weigth;public:Per() { cout << "Per::无参构造函数" << endl; };Per(string name, int age, double h, double w):name(name), age(age), hight(new double(h)), weigth(new double(w)){cout << "Per::有参构造函数" << endl;};~Per(){cout << "Per::析构函数" << endl;};Per(const Per &other):name(other.name),age(other.age),hight(new double(*(other.hight))),weigth(other.weigth){delete hight;cout << "Per::拷贝构造函数" << endl;};void show(){cout << "姓名=" << name << endl;cout << "年龄=" << age << endl;cout << "身高=" << *hight << endl;cout << "体重=" << *weigth << 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, double hight, double weight):score(score),p1(name, age, hight, weight){cout << "Stu::有参构造函数" << endl;};~Stu(){cout << "Stu::析构函数" << endl;};Stu(const Stu &other):score(other.score),p1(other.p1){cout << "Per::拷贝构造函数" << endl;};void show(){p1.show();cout << "成绩=" << score << endl;}};int main()
{Stu s1;Stu s2={ 98,"张三", 19, 1.75, 46 };s2.show();Stu s3=s2;s3.show();return 0;
