Well, first off your reading the "Getting Started with the
2012 frc control system" for the
2013 FRC control system. A link to the 2013 Getting Started with C++ page,
wpilib.screenstepslive.com/s/3120/m/7913, should prove better help for you. I found the link for it on the Technical Resources KOP (Kit of Parts) page
here. Good luck, stay safe, learn new things, and have fun!
