Well, if the issue really is style...

Don't ever use single-character variable names.  I use 'ix' for
loop index variables for which I can come up with no better name,
but this happens rarely.  If you're looping ove 'x' then 'x' means
something more to you than just 'x' when you're writing the code.
But it may not be immediately obvious later.

There's bound to be a more useful name for NUM_ELEMENTS too.
