思维导图:
题目:
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。
代码:
#include <iostream>
using namespace std;
class Per
{
private:
string name;
int age;
int *heigh;
int *weith;
public:
//构造函数
Per()
{
cout << "Per::无参构造函数" << endl;
cout << this << endl;
}
Per(string name,int age,int heigh,int weith):name(name),age(age),heigh(new int(heigh)),weith(new int(weith))
{
cout << "Per::有参构造函数" << endl;
cout << this << endl;
}
//析构函数
~Per()
{
cout << "Per::析构函数" << endl;
cout << this << endl;
}
//拷贝函数
Per(const Per &other):name(other.name),age(other.age),heigh(new int(*other.heigh)), weith(new int(*other.weith))
{
cout << "Stu::拷贝构造函数" << endl;
cout << this << endl;
}
void show()
{
cout << "名字=" << name << endl;
cout << "年龄=" << age << endl;
cout << "身高=" << *heigh << endl;
cout << "体重=" << *weith << endl;
}
};
class Stu
{
private:
int score;
Per p1;
public:
//构造函数
Stu()
{
cout << "Stu::无参构造函数" << endl;
cout << this << endl;
}
Stu(int score,string name,int age,int heigh,int weith):score(score),p1(name,age,heigh,weith)
{
cout << "Stu::有参构造函数" << endl;
cout << this << endl;
}
//析构函数
~Stu()
{
cout << "Stu::析构函数" << endl;
cout << this << endl;
}
//拷贝函数
Stu(const Stu &other):score(other.score),p1(other.p1)
{
cout << "Stu::拷贝构造函数" << endl;
cout << this << endl;
}
void show()
{
cout << "成绩=" << score << endl;
cout << this << endl;
p1.show();
}
};
int main()
{
Stu s1;
Stu s2(88,"sss",22,123,32);
cout << "&s1=" << &s1 << endl;
cout << "&s2=" << &s2 << endl;
s2.show();
Stu s3=s2;
s3.show();
cout << "&s3=" << &s3 << endl;
return 0;
}
