If you are interested in learning Object Oriented C++ for FRC and have access to an NXT then team 2704 has a full tutorial, from never having coded before all the way to programming a full robot at
FirstPlusPlus.com
The code we do is true C++, not RobotC, and is directly applicable to the FRC robotics.
We can also arrange Skype or Google Hangout lessons if you want those.
