I learning to write C code but i cant compile from the Xcode Program (this is the one i got for the iPhone Dev Kit, not sure if that makes a difference) but after i write the small program "hello World" i go to compile and its grayed out. what gives? what did i do wrong?

Tell us, exactly, how you created your project. Note if you did not start with a new project then you can't compile from within XCode. Creating a new C file or whatever outside a project will not work...

gcc -o programname filename.c

Ok so i tried gcc -0 hello hello.c
and it makes a second file with no ext. what ext do i use to for the out put file? In windows it makes a exe file what does it make in the mac os?

Mac OS executables actually don't have any extension at all.

It is not -0 (zero) it is -o (small letter o). There is no need for an extension for Mac OS X executables.
