Does robotc support regular C?
I tried compiling a simple c program:

void main () {}

or

#include <stdio.h>
main () {printf ("Hello World");


I get errors.

What is the difference between regular C and RobotC programming ?
If it is different, where can can I get a guide for learning RobotC ?

Thanks,

Syntactically RobotC is a lot like C. It has many keywords in common with C and the programs are structured much like C. RobotC however is not C.

To get a good idea of how to write RobotC apps, open the Sample programs and read them. There is also some documentation that comes with RobotC explaining the API.

I hope this helps!

Dtrotzjr made a great point, the sample programs help alot in seeing the similarities and differences between Robot C and C

As far as the three sample bits you showed, Robot C uses
task main()
{
}
when initializing a program

When including a file, you have to bracket the filename in "" instead of <>

Also if you want to print text or variables to a screen, you have to use Robot C exclusive commands. One way to find these commands is to double click on a category in the Code Templates Toolbar on the left part of the screen and it will bring up Robot C exclusive commands to activate special functions of your NXT or RCX.

Good Luck
