C++ is a widely-used programming language. As a result, the web is full of
on-line references, tutorials, FAQs, and discussion groups. Some of them
know what they are talking about, but not all. Some violate copyright laws.
Many are based on Microsoft libraries which often are non-portable. Here
are some sites that may be useful:

STL Reference
