Does the IDE of ARDUINO support the FULL C language standard ,
or is it a "shrinked" version of the standard C language compiler?
I am not talking about C commands that are relevant to desktop apps like FILE related C statements.
Thanks

The Arduino IDE and associated compiler use C++ and provides the vast majority of C++ language features.
Are you interested in any particular features ?
The only thing you have to be aware of is that you are in an embedded environment which means limited memory, so some things you can happily do in C++ on a laptop might fall over on an Arduino.
