#1 This is the wrong board, it should be in the C++ Board.
#2 Not everyone here is an expert, so don't be expecting an immediate answer.
#3 Don't bump threads. This is part of the forum guidelines (and is essentially the only thing you did wrong).
With all that being said, the problem is that you compiler isn't finding iostream include. This means, I'd bet, that your compiler isn't set up properly. Since I don't know what compiler you're using, I can't tell you how to fix your problem. And even when you do, I can't guarantee a solution for you, as I may not have experience with it, in which case you'll have to wait for someone more experienced to come up.
In the meantime, I'd try and find where your compiler is looking for the include files.
