Easy to figure out, but not considered a great code editor.

Compiling/Running C Programs
Under cygwin/Mac OSX/CUNIX, type gcc filename.c to compile
your program. It will generate a file called "a.out" or
"a.exe". To run it, type "./a.exe" or "./a.out". The dot slash
at the beginning tell a unix system to execute the file called
"a.exe" or "a.out" in the current directory.
You can use gcc -o outputfilename filename.c
to send your
compiled program to a file other than a.out or a.exe.
If you have windows and don't want to use cygwin, you may
download the free TurboC compiler.
