Getting started c/c++ guide

[krsmith28p]

In http://www.koding.com/docs/getting-started-c-cpp, the example code, (as seen on chrome on my chromebook, at least), does not have any file target after "#include", and my attempt failed until I included "<"stdio.h">" afterwards. Those "<" may be the culprit, perhaps, especially since they dont show on the preview here, either (without the extraquotes)?
