What's the difference between “STL” and “C++ Standard Library”?

Question

Someone brought this article to my attention that claims (I\'m paraphrasing) the STL term is misused to refer to the entire C++ Standard Library instead of the part

Answer 1

C++ Standard Library includes C++ STL

The contents of the C++ standard library are:

1. C++ version of C language header file
2. C++ IO header file
3. C++ STL

So please don’t confuse the C++ standard library with STL.
