I will second the various comments that you should focus on concepts rather than languages per se. That being said, if you want a resource for c and c++, check out the newsgroups comp.lang.c and comp.lang.c++ (especially the FAQ for comp.lang.c++, which is a pretty impressive guide in and of itself, and is available at
http://www.parashift.com/c++-faq-lite/. The comp.lang.c FAQ is at
http://www.eskimo.com/~scs/C-faq/top.html).
(Newsgroups are a virtual-community technology which predates the web, but are still around and going strong. In fact, the author of one of the most widespread early newsreaders ("rn") was none other than Larry Wall himself. But I digress...).
Nowadays, you can quite easily read news over the web via
http://groups.google.com, and Netscape still has a newsreader built in...
Also, if you plan on becoming a perl guru or a Microsoft ASP guru (or both), in either case you should also know C well -- the best/most flexible way of accessing the internals of either platform is through C. Case in point -- perl itself (at least up through perl 5) is written in C.
Best of luck...
