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;
}
