6月5号作业
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 Slu
{
private:double performance;
public:Slu(){cout << "无参构造函数" << endl;}Slu(double performance):performance(performance){cout << "有参构造函数" << endl;}void shor(){cout << "成绩" << performance << endl;}
};
class Per
{
private:string name;int age;double *stature;double *weight;Slu p1;
public:Per(){cout << "无参构造函数" << endl;}Per(string name,int age,double stature,double weight,double performance):name(name),age(age),stature(new double(stature)),weight(new double(weight)),p1(performance){cout << "有参构造函数" << endl;}void show(){cout << "姓名=" << name << " " << "年龄=" << age << " " << "身高=" << *stature << " " << "体重=" << *weight << endl;p1.shor();}~Per(){delete stature;stature=nullptr;delete weight;weight=nullptr;}
};int main()
{Per s1;Per s2("张三",28,180.8,165.44,99);s2.show();return 0;
}
