1.定义一个Person类，包含私有成员，int *age，string &name，一个Stu类，包含私有成员double *score，Person p1，写出Person类和Stu类的特殊成员函数，并写一个Stu的show函数，显示所有信息。
#include <iostream>
#include <iomanip>using namespace std;class Person{
private:int *age;string &name;
public:Person(int age, string &name):age(new int(age)),name(name){cout << "调用Person构造函数" << endl;}Person(const Person &other):age(new int(*(other.age))), name(other.name){cout << "调用Person拷贝构造函数" << endl;}Person &operator=(const Person &other){*age = *(other.age);cout << "调用Person拷贝赋值函数" << endl;return *this;}~Person(){delete age;cout << "调用Person析构函数" << endl;}int get_age();string get_name();
};int Person::get_age(){return *age;
}string Person::get_name(){return name;
}class Stu{
private:double *score;Person p1;
public:Stu(double score, int age, string &name):score(new double(score)), p1(age,name){cout << "调用Stu构造函数" << endl;}Stu(const Stu &other):score(new double(*(other.score))), p1(other.p1){cout << "调用Stu拷贝构造函数" << endl;}Stu &operator=(const Stu &other){*score = *(other.score);p1 = other.p1;cout << "调用Stu拷贝赋值函数" << endl;return *this;}~Stu(){delete score;cout << "调用Stu析构函数" << endl;}void show();
};void Stu::show(){cout << "score = " << *score << " age = " << p1.get_age() << " name = " << p1.get_name() << endl;
}int main(){string name = "张三";Stu a(78.4, 18, name);a.show();}
