作业11.30

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;
    double weight;
    double height;
public:
    Per()
    {
//        cout << "Per::无参构造函数" << endl;
    }
    Per(string name,int age,double weight,double height):name(name),age(age),weight(weight),height(height)
    {
//        cout << "Per::有参构造函数" << endl;
    }
    ~Per()
    {
//        cout << "Stu::析构函数" << endl;
    }
    Per(const Per &other):name(other.name),age(other.age),weight(other.weight),height(other.height)
    {
//        cout << "Stu::拷贝函数" << endl;
    }
    void show()
    {
        cout << "Per name=" << name << endl;
        cout << "Per age=" << age << endl;
        cout << "Per weight=" << weight << endl;
        cout << "Per height=" << height << endl;
    }
};
class Stu
{
private:
    double score;
    Per p1;
public:
    Stu()
    {
//        cout << "Stu::无参构造函数" << endl;
    }
    Stu(double score,string name,int age,double weight,double height):score(score),p1(name,age,weight,height)
    {
//        cout << "Stu::有参构造函数" << endl;
    }
    ~Stu()
    {
//        cout << "Stu::析构函数" << endl;
    }
    Stu(const Stu &other):score(other.score)
    {
//        cout << "Stu::拷贝函数" << endl;
    }
    void show()
    {
        cout << "Stu score=" << score << endl;
        p1.show();
    }
};

int main()
{
    Per p1;
    Per p2("张三",28,56,176);
    Per p3(p2);
    p3.show();
    Stu s1;
    Stu s2(98,"李四",27,55,176);
    Stu s3=s2;
    s2.show();
    return 0;
}
