Ndless sdk questions

So looks like the docs are offline so i have to rely on samples + available headers.
I've been playing around with the sources and i don't know why in "hellpworld-cpp" the printf clears the screen to black but if i try to compile a c program with printf it doesn't do anything. Why it happens?
Btw does anyone still has "The Ndless Editor" or recommends any IDE? I've been using Notepad++.
Thanks,
Krystal
