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 Stu
{
private:double sroce;
public:Stu(double sroce):sroce(sroce){cout << "Stu::有参构造函数" << endl;}~Stu(){cout << "Stu::析构函数" << endl;}void show(){cout << sroce << endl;}
};
class Per
{
private:string name;int age;double *height;double *weight;Stu s;
public://构造函数初始化Per(string name,int age,double height,double weight,double sroce):name(name),age(age),height(new double(height)),weight(new double(weight)),s(sroce){cout << "Per::有参构造函数" << endl;}//析构函数释放堆区空间~Per(){cout << "Per::析构函数" << endl;delete height;height=nullptr;delete weight;weight=nullptr;}//输出初始化之后的值void show(){cout << name << " " << age << " " << *height << " " << *weight << " ";s.show();}
};
int main()
{Per p1("lisi",18,178.9,140.5,99.9);p1.show();return 0;
}
