8.7作业

1.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 <iostream>using namespace std;class Per
{
private:string name;int age;double *height;double *weight;
public:Per(){cout << "Per::无参构造函数" << endl;}Per(string name,int age,double height,double weight):name(name),age(age),height(new double(height)),weight(new double(weight)){cout << "Per::有参构造函数" << endl;}Per(const Per &other):name(other.name),age(other.age),height(new double(*(other.height))),weight(new double(*(other.weight))){cout << "Per::拷贝构造函数" << endl;}~Per(){delete height;delete weight;height = nullptr;weight = nullptr;cout << "Per::析构函数" << endl;}void show(){cout << name << " " << age << " " << *height << " " << *weight << " ";}
};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 height,double weight):score(score),p1(name,age,height,weight){cout << "Stu::有参构造函数" << endl;}Stu(const Stu &other):score(other.score),p1(other.p1){cout << "Stu::拷贝构造函数" << endl;}~Stu(){cout << "Stu::析构函数" << endl;}void show(){p1.show();cout << score << endl;}
};int main()
{Stu s1;Stu s2(100,"张三",18,180,80);s2.show();return 0;
}
