Any Good C/C++ online references?

I'm not even sure what I have on my hard drive. It seems I've broken the help indexer, so perhaps what I'm seeking is right here, and I just can't get at it. I'm looking for a good online reference for C/C++. I haven't written in these languages for years, and I was never fluent. Does anybody know of a good online reference for these? Are any included with SuSE 8.1? I can't get the C/C++ documentation working for KDevelop 2.1.5 either, so if your answere is there, then please let me know how to get it set up. STH
