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 *high;double weight;
public:Per(){cout << "Per::无参构造函数" << endl;}Per(string name,int age,double high,double weight):name(name),age(age),high(new double(high)),weight(weight){cout << "Per::有参构造函数" << endl;}Per(const Per &other):name(other.name),age(other.age),high(new double(*(other.high))),weight(other.weight){cout << "Per::拷贝构造函数" << endl;}~Per(){cout << "Per::析构函数" << endl;}void show(){cout << "name:" << name << endl;cout << "age:" << age << endl;cout << "high:" << *high << endl;cout << "weight:" << weight << endl;delete high;}
};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 high,double weight):score(score),p1(name,age,high,weight){cout << "Stu::有参构造函数" << endl;}Stu(const Stu &other):score(other.score),p1(other.p1){cout << "Stu::拷贝构造函数" << endl;}~Stu(){cout << "Stu::析构函数" << endl;}void show(){cout << "score:" << score << endl;p1.show();}
};int main()
{Stu s1(92.5,"jack",19,188.5,55.2);s1.show();Stu s2(s1);s2.show();return 0;
}
