Hi Sarim,
don't get me wrong, but if you try and compile these questions, you will get a lot of answers. For example the questions about the valid identifiers.
Believe me, if you hack this stuff and try it, you will have a greater benefit than just posting these questions and reading the answers...
One more thing. If you really have difficultiest with some questions, be sure, that you post them right. For example question 2, none of these are valid, cause they all start with uppercase letters (i doubt that in the question they started with uppercase letter, rite )
I will have a look at the more complex ones, so be patient, on some of these questions you will get an answer (of course only if i know the solution )
cheers
Oliver
