Of course, I want the answer to be that there isn't any point if
parentheses will be used anyway.
The answer, of course, is that the condition of your "if" clause is not
true. In the overwhelming majority of the cases, people do not use
parentheses to clarify the order of evaluation that is guaranteed by C's
grammar rules. They only use them in the cases where they feel that
there's a significant chance of confusion. Of course, that depends upon
your audience. If I was required to write code in such a way that you
would have trouble misunderstanding it, I'd write
a = m*x + b;
as
a = ((m*x)+b);
I internalized C's grammar rules a long time ago (which causes problems
on the rare occasions when they've changed them). The main exception are
the bit-wise operators which are well known as having the wrong
precedence - but I've seldom needed to use those operators.
As a result, I seldom have any confusion as to the order of evaluation,
which makes it very hard for me to realize that it might be a good idea
to put in some redundant parentheses to clarify that order for other
people. That means that some of my code is probably more cryptic than it
should be.
