Yes, if you have a backup copy, for example on a tape.
But I assume you don't hae it, so the only anwser is:
  No, you cannot restore it, anyhow.

But wait, theoretically there is a minimal chance to restore some parts, but only if you have not written anything else on the harddisk since you issued the cc command:
   use a tool (like dd then pipe it to od) to read the raw disk device and serach for the text. Be careful, 'cause the text may not apear in the sequence you expect it.

yeah re-write the program, it is much quicker and safer than trying to to read raw disk device, all being considered

If you are using an ext2 filesystem (you probably are) you can try to undelete that file, I guess. There is a how to in linuxdoc.org about how to do it.

Also, there is a chance your text editor does automatic backups. For example, emacs saves a backup copy (the last version before the one you saved) in a file ending in the character ~, and may do autosave (saving every so often :) in files starting with #. Check for your text editor, you may be lucky :)
