#include <iostream>

using namespace std;

class Hum
{
protected:
    string name;
public:
    Hum(string name)
        :name(name)
    {
        cout << "hum 构造" << endl;
    }
    virtual void Skill()
    {
        cout << name << ": hum skill" << endl;
    }
};

class Child : public Hum
{
public:
    Child(string name)
        :Hum(name)
    {

    }
    void Skill() override
    {
        cout << name << ": Child skill" << endl;
    }
private:

};
int main()
{
    Hum a = Child("cc");
    a.Skill();

    Child b("cc");
    Hum& A = b;
    A.Skill();

    Hum *c = &b;
    c->Skill();
