6.5作业

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。

#include <iostream>

using namespace std;

class Per
{
private:
    string name;
    int age;
    double *height;
    double *weight;
public:
    Per(){cout << "Per::无参构造函数" << endl;}
    Per(string name, int age, double height, double weight):name(name),age(age),height(new double(height)),weight(new double(weight))
    {
        cout << "Per::有参构造函数" << endl;
    }
    ~Per()
    {
        cout << "Per::析构函数" << endl;
        delete height;
        delete weight;
    }
    void show()
    {
        cout << name << endl << age << endl << height << endl << weight << 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 height, double weight):score(score),p1(name,age,height,weight)
    {
        cout << "Stu::有参构造函数" << endl;
    }
    ~Stu()
    {
        cout << "Stu::析构函数" << endl;
    }
};

int main()
{
    Stu s1(100, "zhangsan", 20, 179.5, 67.5);

    return 0;
}
