"Practical Programming in C" summed up the precedence rules in C
thusly:

" Precedence       Operator
      1.            * / %
      2.            + - 

  Put parantheses around everything else."
 
If the meaning of your code depends on the particulars of operator
precedence beyond the very obvious rules above, rewrite it so that it
doesn't. (The same holds for the difference between ++i and i++.)
