Post in the job section and dont forget to mention how much you're willing to pay

First, the use of code tags with posted code is strongly recommended, because it improves readability quite a lot.
See http://www.cplusplus.com/articles/jEywvCM9/

Second, you say "my programming" and thus we assume that you know C++. In other words, you know the C++ constructs that you do use.

Your code does use both cout and printf. Which parts of the C++ Standard Library do they come from? Is one perhaps very similar to the output formatting command that is used in language C?
