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;int *high;int *weight;public:// 构造函数Per(){high = nullptr;weight = nullptr;cout << "无参构造函数" << endl;}Per(string n, int a, int h, int w) : name(n), age(a), high(new int(h)), weight(new int(w)){cout << "有参构造函数" << endl;}// 深拷贝Per(const Per &other) : name(other.name), age(other.age), high(new int(*other.high)), weight(new int(*other.weight)){cout << "拷贝构造函数执行" << endl;}// 析构函数~Per(){delete high;delete weight;high = nullptr;weight = nullptr;cout << "析构函数执行" << endl;}void show(){cout << "name:" << name << endl;cout << "age:" << age << endl;cout << "high:" << *high << endl;cout << "weight:" << *weight << endl;}
};
class Stu
{
private:float score;Per p1;public:// 构造函数Stu(){cout << "无参函数执行" << endl;}Stu(float s , string name , int age , int high , int weigh):score(s),p1(name,age,high,weigh){cout << "有参构造函数执行" << endl;}// 拷贝构造函数Stu(const Stu &other):score(other.score),p1(other.p1){cout << "拷贝构造函数执行" << endl;}// 析构函数~Stu(){cout << "析构函数执行" << endl;}void show(){cout << "score:" << score << endl;p1.show();}
};
int main()
{Per p1; // 无参构造函数Per p2("张三", 18, 170, 70); // 有参构造函数Per p3(p2); // 拷贝构造函数p3.show();Per p4 = p3;cout << "===================" << endl;Stu s1;Stu s2(100,"李四",18,170,70);Stu s3(s2);s3.show();return 0;
