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(string name,int age,double height,double weight):name(name),age(age),height(new double(height)),weight(new double(weight))
    {
        cout << "Per::构造类型" << endl;
    }
    ~Per()
    {
        delete height;
        delete weight;
        height=nullptr;
        weight=nullptr;
        cout << "Per::析构类型" << endl;

    }
    void show()
    {
        cout << name << " " << age << " " << *height << " " << *weight << endl;
    }
};
class Stu
{
private:
    double sroce;
    Per p1;
public:
    Stu(double sroce,string name,int age,double height,double weight):sroce(sroce),p1(name,age,height,weight)
    {
        cout << "Stu::构造类型" << endl;

    }
    ~Stu()
    {

        cout << "Stu::析构类型" << endl;

    }
    void show()
    {
        cout << sroce << " ";
        p1.show();
    }

};
int main()
{
    Stu s1(99.8,"lisi",18,175.6,140.3);
    s1.show();

    return 0;
}
