I realized I have to change my attitude.. now the class looks as
follows:

class ListOfElements{
  private:
     typedef struct element{
          int number;
          next * element;
     }*pointer;
  pointer head;
  public:
  //constructor, destructor etc.
  void addNewElement();
}

And new problem is how to pass private data to function
Sequence reverse (const Sequence& )
Should I write a method for returning head and then use it somehow
(how?) or just copy the data from the field 'number' and in function
reverse call the constructor of a class Sequence with paramter
'number' ?

Using this class ListOfElements, you can now just pass ListOfElements. I
think that a reference would be best.

Incidently, lose the "typedef". Not needed in C++. It will work with it,
but there is no need for it, it's just fluff.

Following won't compile but should give you idea.

void Foo( ListOfElements& List );

int main()
{
   ListOfElements MyList;
   MyList.addNewElement( whatever );
   Foo( MyList );
}

Foo( ListOfElements& List )
{
   // use List here
}
