Speaking as a person who does relatively little C programming, I don't
see much difference between them. The first example is more Pythonic --
for Python. I agree with Barry that it's not much of a virtue for C
However, I do have one nitpick with both your examples; I don't know
whether this is an artifact of them being examples:

Seems to me that magic numbers like this need to be made constants and
explained with a comment.
