     `x += 1' has the same meaning as `++x'.  If the value of the
expression is not used, it is also equivalent to `x++'.  I can think
of no important reason to prefer one of the first two over the other,
and cannot imagine why anyone would call either "generally better."
If the value is not used, I'd also lump the third in with the first
two and choose whichever seems more readable in context.

     None of the three is an atomic operation.
