the only thing I can think of is permissions do you know what they are set to for that file?

what permissions r u talking about i logged on as root
and just created the file so wat permissions???

if you type ls -l in that directory it will list the file permissions

basically i was wondering if the file was allowed to execute on your machine.

Ok.
put the "\n" at the end of the line.

like this.

printf("hello world\n");

Actually it does print without "\n", but when the program exit, the command prompt overwrite the printed line so you can't see it. So you have to append "\n" and give the new line command so that you get back to command prompt only after the printed line. Make sense right?
But in windows, it is not the case I think.

hmm.. I don't know much in that area. I think you should ask this in the Linux-general or Software forum so that you can get the answer faster. Only the programming guys are coming to this forum.
