In Xcode, if I set that flag for the build style, I get no warnings,
but when I set it on a particular file, I do. Is this expected
behavior? I would think you could set it for the whole project, but
it doesn't quite work.
That might suggest why people's suggestions to use -Wparentheses hasn't
worked for me.
While others have pointed out useful warning options, I'd like to
point out a useful coding idiom: Whenever possible, use an r-value on
the left side. e.g., all of the following will generate complaints
from the compiler, whereas the reverse ordering won't:
This wouldn't have helped in my case, since both sides were just ints,
not constants.
