- Thread-topic: Unnecessary Boolean Warning
It¹s not that I object to anyone doing it, if that makes them more
comfortable, but a warning on ³³&&² inside of ³||²² is ridiculous. Everyone
knows that multiplication takes precedence over addition. ³&&² is a
multiplication. ³||² is, welll, almost an addition. (Exor is addition in a
mod 2 system.} Anyone who can¹t at least keep these two straight shouldn¹t
be doing programming. Overall operator precedence is a little more
complicated and I would recommend , for those who don¹t have it all down,
copying the page (two page spread) out of K&E or Stroustroup and taping it
to the wall. (I have done that in the past.) I just think this particular
warning is carrying things to the extreme. What next? Warning: ³*² inside
of ³+²?
I don¹t object to warnings. ³Assignment inside of ³if²² is a good thing,
because it is a common, easily committed, error, and I appreciate the
warning.
