C++作业3

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。

代码：

#include <iostream>using namespace std;class Per
{
private:string name;int age;double *height;double *weight;
public:Per(){cout << "per无参" << 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" << 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" << endl;}~Per(){delete height;delete height;height = nullptr;weight = nullptr;cout << "per析构" << endl;}void show();};void Per::show()
{cout << "name:" << name << endl;cout << "age:" << age << endl;cout << "height:" << *height << endl;cout << "weight:" << *weight << endl;
}class Stu
{
private:double score;Per p1;
public:Stu(){cout << "stu无参" << endl;}Stu(double score,string name,int age,double height,double weight):score(score),p1(name,age,height,weight){cout << "stu有参" << endl;}Stu(const Stu &other):score(other.score),p1(other.p1){cout << "stu拷贝" << endl;}~Stu(){cout << "stu析构" << endl;}void show();
};void Stu::show()
{cout << "score:" << score << endl;p1.show();
}int main()
{Per s1("张三",18,1.7,120);s1.show();cout << "-----------------------" << endl;Per s2(s1);s2.show();cout << "-----------------------" << endl;Stu s3(98,"李四",21,1.8,125);s3.show();cout << "-----------------------" << endl;Stu s4(s3);s4.show();return 0;
}

运行结果：
