Is below implementation of Abstract Factory Design Pattern is correct?

#include<iostream>

using namespace std;

//Abstract Product A

class Document
{

    public:

        virtual void createDocument() = 0;

};


class Word: public Document

{

    public :


        virtual void createDocument()
        {

            cout<<"Document Word is created"<<endl;         

        }
};


class Excel : public Document
{
    public :

        virtual void createDocument()
        {
            cout<<"Document Excel is created"<<endl;            
        }
};

//Abstract Product B


class VideoFile
{

    public:

        virtual void createVideoFile() = 0;

};


class VLC : public VideoFile
{

    public :

        virtual void createVideoFile()
        {
            cout<<"VideoFile VLC is created"<<endl;         

        }
};


class AVI : public VideoFile
{

    public :

        virtual void createVideoFile()
        {

            cout<<"VideoFile AVI is created"<<endl;         

        }
};
