C++day3类

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 

using namespace std;
class Per
{
    string name;
    int age;
    int *hei;
    int *wei;
public:
    Per(string name,int age,int hei,int wei):name(name),age(age),hei(new int(hei)),wei(new int(wei))
    {
        cout << "Per的构造函数" << endl;
    }
    ~Per()
    {
        delete hei;
        delete wei;
        cout << "Per的析构函数" << endl;

    }

    Per(Per &other):name(other.name),age(other.age),hei(new int(*other.hei)),wei(new int(*other.wei))
    {
        cout << "Per的拷贝构造函数" << endl;
    }
    void show()
    {
        cout << name << endl;
        cout << age << endl;
        cout << *hei << endl;
        cout << *wei << endl;
    }
};
class Stu
{
    int score;
    Per p1;
public:
    Stu(int score,string name,int age,int hei,int wei):score(score),p1(name,age,hei,wei)
    {
        cout << "Stu的构造函数" << endl;
    }
    ~Stu()
    {
        cout << "Stu的析构函数" << endl;
    }
    Stu(Stu &other):score(other.score),p1(other.p1)
    {
        cout << "Stu的拷贝构造函数" << endl;
    }
};

int main()
{
    Stu s1(70,"zhangsan",18,180,70);
    Stu s2 = s1;
    Per p1("lisi",20,175,65);
    Per p2 = p1;
    return 0;
}
