If the code is really sufficiently trivial (and I’d guess that most code samples you’ll find on StackOverflow are) you may have a fair use argument in the US. Generally speaking though (and especially for anything nontrivial) you need to respect the license.

But when in doubt, ask for permission or ask a lawyer.
