as HTML is to tag, C++ is to? (what do you call things like cout and cin, etc.)

[13_y/o_noob]

in my IDE (codeblocks) if I type something in (such as num) it gives me a list of things that start with num (numpunct, numeric value or whatever) and other things that I don't know. What do you call these things (streambuf, count, cout, cin, namespace, int, bool)?

And where is a good glossary/table explaining what each one does?

Thanks in advance

Names? If you are looking for a C++ glossary, Bjarne Stroustrup has one: C++ glossary. However, to actually learn how to use these, you are better off working through a book such as Accelerated C++.
