嵌入式学习-C+±Day3

一、思维导图

二、作业

1.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;int *height;int *weight;
public:Per() {cout << "Per::无参构造函数" << endl;}Per(string n,int a,int h,int w):name(n),age(a),height(new int (h)),weight(new int(w)){cout << "Per::有参构造函数" << endl;}void show(){cout << "name = " << name << endl;cout << "age = " << age << endl;cout << "height = " << *height << endl;cout << "weight = " << *weight << endl;}~Per(){cout << "Per::析构函数" << endl;delete height;delete weight;}Per(const Per &other):name(other.name),age(other.age),height(other.height),weight(other.weight){cout << "Per::拷贝构造函数" << endl;}};
class Stu
{
private:int score;Per p1;
public:Stu() {cout << "Stu::无参构造函数" << endl;}Stu(int s,string name,int age,int height,int weight):score(s),p1(name,age,height,weight){cout << "Stu::有参构造函数" << endl;}void show(){cout << "score = " << score << endl;p1.show();}~Stu(){cout << "Stu::析构函数" << endl;}Stu(const Stu &other):score(other.score),p1(other.p1){cout << "Stu::拷贝构造函数" << endl;}};int main()
{Per p;Per p2("zhangsan",18,180,180);p2.show();cout << "============================" << endl;Per p3=p2;p3.show();cout << "============================" << endl;Stu s;Stu s2(99,"lisi",18,180,180);s2.show();Stu s3 = s2;cout << "============================" << endl;p3.show();cout << "============================" << endl;return 0;
}

运行结果
