c++之深拷贝和浅拷贝

#include<iostream>
using namespace std;

class Person {
public:
    int m_age;
    int* m_height;
    Person() {
        cout << "Person默认构造函数" << endl;
    }
    Person(int age, height) {
        m_age = age;
        m_height = new (height);//浅拷贝
        cout << Person(int age)构造函数const Person& p) {
        m_age = p.m_age;
        m_height = int(*p.m_height);//这就是深拷贝操作
        cout << 拷贝构造函数 endl;
    }
    ~Person() {
        将堆区的数据进行释放
        浅拷贝带来的问题就是重复释放，可以利用深拷贝来解决
        if (m_height != NULL) {
            delete m_height;
            m_height = NULL;
        }
        cout << Person析构函数 endl;
    }

};
void test() {
    Person p1(18,178);
    cout << p1的年龄为：" << p1.m_age << 身高为："<<*p1.m_height<<endl;
    Person p2(p1);
    cout << p2的年龄为：" << p2.m_age << " << *p2.m_height << endl;
}
 main() {
    test();
    system(pause");
    return 0;
}
