I end up using google whenever I need to look up a specific function, or find a function to do a specific thing...
MSDN usually has good stuff, but that is more of a reference style than a tutorial style...
I've never used it myself, but a quick google led me to this site: http://www.cplusplus.com/doc/tutorial/
looks like that might help get you back into the basics.
I assume mostly it will be just remembering functions and syntax. I can't imagine someone forgetting the logical stuff
If you still have your textbook you might consider just redoing a couple of your old assignments (assuming you actually programmed in your programming class... I hear some colleges make it all theory)
