I'm familiar with C and just joined my school's robotics club...and Robot C is kinda odd. Can you use all of C's features in Robot C? (enums, casting, etc) What is Robot C? Is it only loosely based on C or is it C with some library? Basically, what are the differences between Robot C and C?

No, RobotC is not standard ANSI C. It is a hybrid between C and C++ with a lot of standard features missing. To name a few, it doesn't allow a function to be re-enter, so no recursion and it doesn't support pointers either.

Thanks. Is there a document that lists all of the differences between RobotC and C or some sort of "Tutorial for C Programmers?"

No, I don't have a document. But there are a lot of posts on this subject. You may want to search for them.

That's what I've been doing, wanted to know if there's documentation on this so I know I'm not wasting my time with searches. Side note: How do you concentrate a string and int in RobotC?

I haven't tried it myself but it looks like RobotC supports sprintf.

If you go to Window > Menu Level and select Expert, the Function Library will grow to show the "Strings" category, which does include sprintf.

One of our current projects is compiling all available commands in ROBOTC into a single document. We're hoping to share that relatively soon. In the mean time, quite a bit is documented here: http://www.robotc.net/support/vex/WebHelpCortex/

and tutorials for beginners can be found here: http://www.education.rec.ri.cmu.edu/pro ... index.html

I assume this document only covers all the RobotC provided functions but not about listing the differences between RobotC and ANSI C which was the original question from jaymc.

Actually we're hoping to do both. The ROBOTC functions portion is a higher priority, but a comparison piece will come after.

The question of how to "concentrate" strings, which I assume means concatenate, is interesting. I stumbled on a document that says RobotC has many nifty string methods:

http://carrot.whitman.edu/Robots/NXT/Strings.htm

It says you can concatenate two strings with the "+" operator:

It also says that assigning an int to a string formats the integer to represent it as a string: Pretty slick! I did not verify this, I'm just summarizing the doc at the URL above!
