@Dennis When you have a minute, can you pull ecpp, and if you don't mind, update the hello world (for C and C++) to this? Thanks in advance, and the best of luck to your friend
Is there any chance you could install the Communications package for Octave? (octave.sourceforge.io/communications) It provides the much better de2bi and bi2de functions over the default dec2bin and bin2dec, which is required for virtually all bit manipulation challenges.
