Practically everyone I know --- including me --- use parentheses everywhere in C simply because that's the only way to keep things straight in our heads. I'd represent the above as '((x >= 0) && (x <= 10))', for example. > A (the?) great source of confusion in C priorities is '&' and '|', > which for historical reasons have a "wrong" priority. The one that always gets me is this: i = i + j<<10; (<< has a lower priority than +!) But what's the issue with & and |? & has a higher priority than |, which is what I'd expect (boolean multiply vs boolean add). Of course, many years of C programming may have twisted my mind... -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ │ life←{ ↑1 ⍵∨.^3 4=+/,¯1 0 1∘.⊖¯1 0 1∘.⌽⊂⍵ } │ --- Conway's Game Of Life, in one line of APL
