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
