I got this code snippet basically off cplusplus.com my problem is though
when I ouput myLong the outputted number isn't 200, its 2000.

Also, you should be aware that there are better (or at least safer) methods available in C++ for performing conversions between arbitrary types and strings (e.g. boost::lexical_cast<>(), which is both safe and concise).

I will also look into boost
