I found this web site on the web. It appears to be course notes from a Computer Science class, but it is very complete and very well written.
The website is http://www.cs.cf.ac.uk/Dave/C/CE.html
I find it very useful when looking up something that "slipped my mind" at the moment, like structs about 10 minutes ago.
If you are a beginner and want to learn C++, or an expert that just forgot, this may come in very handy.
