C++day3

 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 

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 name, int age,int height,int weight):name(name),age(age),height(new int(height)),weight(weight)
    {
        cout << "Per::有参构造函数" << endl;
    }


    ~Per()
    {
        cout << "Per::析构函数" << endl;
    }

    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:
    double score;
    Per per;
public:
    Stu()
    {
        cout << "Stu::无参构造函数" << endl;
    }

    Stu(double score,string name, int age,int height,int weight):score(score),per(name,age,height,weight)
    {
        cout << "Stu::有参构造函数" << endl;
    }


    ~Stu()
    {
        cout << "Stu::析构函数" << endl;
    }

    //拷贝构造函数
    Stu(const Stu &other):score(other.score)
    {
        cout << "Stu::拷贝构造函数" << endl;
    }

};

int main()
{
    Stu s1;
    Stu s2(98,"zhangsan",18,160,100);
    Stu s3(s2);

    return 0;
}
