I agree with the requirement for the parenthesis,
simply because it helps
separate the various conditions that are being tested for. Even looking at
The conditions are clearly seperated by || or by &&. It should be
instantly clear that the comparison is higher than || and && in the
order of operations.
Something like "if (a == (b || c) > d)" wouldn't make sense anyway.
Do not mess this up with bracing things like
if ((a == 0 || a > 2) && b < 0)
Although the braces are not needed, it makes sense to set them.
The parentheses are not needed? You better check your
C book for
operator precedence. && has higher precedence than ||, so in this
case the parentheses are needed. This is also why using parentheses
is a good idea, because you never know if the original author has any
idea about operator precedence. The use of parentheses makes the
original intention clear to other authors.
Sorry, of cause you are right. my fault. I initially wanted to write
something different, got it messed up.. ;-)
