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。
#include <iostream>using namespace std;
class Person
{string name;int age;int *high;double *weight;
public:Person():name("路人甲"),age(18),high(new int(175)),weight(new double(45.00)){cout << "person的无参构造" << endl;}Person(string name,int age,int high,double weight):name(name),age(age),high(new int(high)),weight(new double(weight)){cout << "person的有参构造" << endl;}~Person(){delete high;delete weight;cout << "person的析构函数" << endl;}void show(){cout << " 姓名:" << name << " 年龄:" << age << " 身高:" << *high << " 体重:" << *weight << endl;}
};
class Student

public:Student():score(60.00),p1(){cout << "students的无参构造" << endl;}Student(string name,int age,int high,double weight,float score):score(score),p1(name,age,high,weight){cout << "students的有参构造" << endl;}~Student(){p1.~Person();cout << "student的析构函数" << endl;}void show(){cout << "成绩:" << score;p1.show();}
};int main()
{Person p2;p2.show();Student s1("浮生",22,185,53.03,86.5);s1.show();return 0;
