一、思维导图

二、习题

#include <iostream>using namespace std;class Per
{
private:string name;int age;float * high;float * weight;
public://有参构造函数Per(string n,int a,float h,float w):name(n),age(a),high(new float (h)),weight(new float (w)){}//析构函数~Per(){delete high;  //释放堆区空间delete weight;}//拷贝构造函数Per(const Per &other):name(other.name),age(other.age),high(new float (*(other.high))),weight(new float (*(other.weight))){}//输出函数void show(){cout << "姓名:" << name << endl;cout << "年龄:" << age << endl;cout << "身高:" << *high << endl;cout << "体重:" << *weight << endl;}
};class Stu
{
private:float sorce;Per p1;
public:Stu(float s,string name, int age,float high,float weight):sorce(s),p1(name,age,high,weight){cout << "有参构造函数" << endl;}//拷贝构造函数Stu(const Stu &other):sorce(other.sorce),p1(other.p1){}//输出函数void show(){cout << "成绩:" << sorce << endl;}Per p2=p1;//析构函数会自动调用Per的析构函数
};
int main()
{Stu s1(98,"张三",18,175,65);s1.show();s1.p2.show();return 0;
}
