You have seen pages like this before, with bunches of links but few explanations of what they are for or how useful they are. I will try to categorize and describe them better sometime. If you have any comments about how especially useful or useless something is then let me know. These are all the links I have accumulated that are, or seem to be, related to C++.
A copy of the "Working Paper for Draft Proposed International Standard for Information Systems — Programming Language C++" is available by FTP ("to improve your own understanding of C++") from CD2 on ftp.research.att.com. This is a draft copy of the C++ standard, but is very close to the final standard. Note that there are two types of files; you probably do want the PDF files and probably do not want the PS (PostScript) files. See the CD1 on ftp.research.att.com README file for more details.
The following sites are good for all the other categories shown below.

These are web sites (like mine) that are (or at least appear to me to be) the result of an individual programmer.

leunen.com - homepage by Michel Leunen; more useful for Borland C++ programmers but the Socket class for "basic client/server and UDP/TCP functionalities" looks useful
John Arrizza's web site has sample source code in many languages, including C#, C++ and C
The following includes many useful links but some of them I am not sure about.
ISO/IEC JTC1/SC22/WG14 - C is the official home of the international standardization working group for C.

C++ FAQ LITE is kind of a sample for the C++ FAQ Book.
C++ Home is not the home for the C++ language. I do not know how useful the site is or is not. I am certainly skeptical of anything named with a self-appointed designation (such as "Healthy Choice").
