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;
}
