I've just installed fedora core 3 , actually I'm a firsttime user of linux. I have learnt c programming in windows xp, I wanted it to do in linux. So once I've written a c program in gedit and then I clicked action which in the desktop and then I choosed run and I wrote there gcc and the name as I've saved. But I saw no changes and again there I wrote gcc-o hello with its name and nothing happens.

So please tell me step by step how to write a c program and compile it and then run it.

please help step by step how to write a c program and compile it and then run it. I've already learnt c programming in windows(turbo c) platform. I wanted it to do in fefora core 3.

What do you mean by "nothing happens"?? We need more details. You're meant to open a terminal window and run gcc there. Let's assume for a moment your source file is called hello.c. Running "gcc hello.c" (without quotes, obviously) will create an executable called a.out, which you can run with "./a.out" (without quotes again). If you use "gcc -ohello hello.c", then the executable will be called hello, which you can run with "./hello". That's pretty much all there is to it. You can add extra gcc options to show warnings and other things (see the gcc man page), but those aren't important for the time being.

Edit: please be patient :/.
