Explain line by line the following C++ code?
Hey that's not a very good question to ask here. We are here to help you, not serve you.


So instead of giving a junk code and ordering others to explain the damn code, point to the specific line and ask to explain that line. Hope you got my point.
Reply:Damn, that code is just hard enough to read that I couldn't be bothered trying to comprehend it. Damn Yahoo! answers for not keeping indentation.
Reply:hey are you reading Programming for Dummies? Because I'm reading it too
