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;
//构造Per类
class Per
{
private:
string name;
int age;
double *height;
double *weight;
public:
//无参构造函数
Per()
{
cout << "Per::无参构造函数" << endl;
}
//有参构造函数
Per(string name, int age, double height, double weight):name(name), age(age), height(new double(height)), weight(new double(weight))
{
cout << "Per::有参构造函数" << endl;
}
//析构函数
~Per()
{
cout << "Per::析构函数" << endl;
}
//拷贝构造函数
Per(const Per &other):name(other.name), age(other.age), height(new double(*(other.height))), weight(new double(*(other.weight)))
{
cout << "Per::拷贝构造函数" << endl;
}
};
//构造Stu类
class Stu
{
private:
int score;
Per p1;
public:
//无参构造函数
Stu()
{
cout << "Stu::无参构造函数" << endl;
}
//有参构造函数
Stu(int score, string name, int age, double height, double weight):score(score), p1(name, age, height, weight)
{
cout << "Stu::有参构造函数" << endl;
}
//析构函数
~Stu()
{
cout << "Per::析构函数" << endl;
}
//拷贝构造函数
Stu(const Stu &other):score(other.score), p1(other.p1)
{
cout << "Stu::拷贝构造函数" << endl;
}
};
int main()
{
Per p0; //无参构造函数
Per p1("张三", 19, 100, 180); //有参构造函数
Per p2 = p1; //拷贝构造函数
Stu s0; //无参构造函数
Stu s1(98,"zhang",24,64,180); //有参构造函数
Stu s2 = s1; //拷贝构造函数
return 0;
