Some of us could, but I think you really should find a better place
for this kind of questions.  There's a special newsgroup for beginners
learning C or C++ programming in the 'alt' hierarchy:
alt.comp.lang.learn.c-c++, which is much better suited to this kind of
question.

Or just get yourself a good textbook and learn it.

No.  Note how one assignment is made to 'n', the other to '*n'?  That
discinction is _important_.

It's not a 'pointer to nl'.  'nl' is a 'pointer to something'.
