Oh, be that way. :-) In the context you're quoting, both expressions are
equivalent, but they aren't equivalent in all contexts.  (But then, what
is?)  For example, you would be really concerned about this if you're
converting "if (x += 1)" into "if (x++)", since they're not the same.
You could however convert to "if (++x)".

The two *statements* (not expressions) "x++;" and "++x;" are
practically the same,  since they have the side effect of
incrementing x in common, and the result value is discarded.
