Based on the comments below the question, what the OP seems to want is a comprehensive answer about the behavior of all of his examples in every possible compiler. That's not really what we do here; Stack Overflow is not a free research service.
Users are expected to show some effort; if the OP really wants to know the answer to the question posed in their comment, the best way they can do that is to read up on the language specification, and try out their examples on their own, using a couple of compilers.
In the case of this particular user, there may be some suspicion of trolling; he posted a question titled "Please downvote this so that I can get a peer pressure badge," and another one titled "Please solve my homework for me." The community is not stupid; they realize that they can easily perma-ban a user at the IP level by casting a lot of downvotes and deleting the question, and they don't even need a mod to do it.
