Sparked from a conversation I had with a friend and fellow programmer some odd hours ago, I decided it would be fun to try to make a program that would run in more than one language. Initially, I thought of Brainf*ck and C(++), but my friend suggested I add Whitespace to the mix too. As it turned out, I managed to throw in Python as well.
After some kind people in #esoteric@irc.freenode.net (I joined originally because it was my first foray into the madness that is Whitespace) told me that this is what is called a polyglot, they helped me shave the last fat off and this is the result. A 384 byte “Hello World!\n” that works in Brainf*ck, Whitespace, Python and C++. Not the worst thing I’ve spent a sleepless night on.
As for acknowledgements, I admit that the bf version was one I had lying around, and I don’t know if it was my own or someone else’s. I did the ws version myself because I couldn’t find a working version anywhere. I do owe thanks to coppro and immibis from #esoteric, they were most helpful in the final stages of the process.
UPDATE: reddit users mallardtheduck, isionous and youreameme have suggested further enhancements, which have resulted in shaving off a further 28 bytes, so here is an updated version weighing in at 356 bytes. Many thanks, reddit!
Its… beautiful.
Looks great
Works in Perl too.
Totally Sweet man

Almost, but not quite – it doesn’t output a linebreak after the “Hello World!”.
Also works in Ruby.
@frangossauro
Same problem as with perl – it could be remedied by dropping support for python I suppose…
Removing the first line (“#include “cstdio”"), if possible, and adding a semicolon (“;”) after “print(“Hello World!”)” makes it work for JavaScript and Lua.
