Here's a quick snippet of code that apparently produces the lyrics to "99 bottles of beer on the wall":

Code:

>+++++++++[<+++++++++++>-]<[>[-]>[-]<<[>+>+<<-]>>[<<+>>-]>>> [-]<<<+++++++++<[>>>+<<[>+>[-]<<-]>[<+>-]>[<<++++++++++>>>+< -]<<-<-]+++++++++>[<->-]>>+>[<[-]<<+>>>-]>[-]+<<[>+>-<<-]<<< [>>+>+<<<-]>>>[<<<+>>>-]>[<+>-]<<-[>[-]<[-]]>>+<[>[-]<-]<+++ +++++[<++++++<++++++>>-]>>>[>+>+<<-]>>[<<+>>-]<[<<<<<.>>>>>- ]<<<<<<.>>[-]>[-]++++[<++++++++>-]<.>++++[<++++++++>-]<++.>+ ++++[<+++++++++>-]<.><+++++..--------.-------.>>[>>+>+<<<-]> >>[<<<+>>>-]<[<<<<++++++++++++++.>>>>-]<<<<[-]>++++[<+++++++ +>-]<.>+++++++++[<+++++++++>-]<--.---------.>+++++++[<------ ---->-]<.>++++++[<+++++++++++>-]<.+++..+++++++++++++.>++++++ ++[<---------->-]<--.>+++++++++[<+++++++++>-]<--.-.>++++++++ [<---------->-]<++.>++++++++[<++++++++++>-]<++++.----------- -.---.>+++++++[<---------->-]<+.>++++++++[<+++++++++++>-]<-. >++[<----------->-]<.+++++++++++..>+++++++++[<---------->-]< -----.---.>>>[>+>+<<-]>>[<<+>>-]<[<<<<<.>>>>>-]<<<<<<.>>>+++ +[<++++++>-]<--.>++++[<++++++++>-]<++.>+++++[<+++++++++>-]<. ><+++++..--------.-------.>>[>>+>+<<<-]>>>[<<<+>>>-]<[<<<<++ ++++++++++++.>>>>-]<<<<[-]>++++[<++++++++>-]<.>+++++++++[<++ +++++++>-]<--.---------.>+++++++[<---------->-]<.>++++++[<++ +++++++++>-]<.+++..+++++++++++++.>++++++++++[<---------->-]< -.---.>+++++++[<++++++++++>-]<++++.+++++++++++++.++++++++++. ------.>+++++++[<---------->-]<+.>++++++++[<++++++++++>-]<-. -.---------.>+++++++[<---------->-]<+.>+++++++[<++++++++++>- ]<--.+++++++++++.++++++++.---------.>++++++++[<---------->-] <++.>+++++[<+++++++++++++>-]<.+++++++++++++.----------.>++++ +++[<---------->-]<++.>++++++++[<++++++++++>-]<.>+++[<-----> -]<.>+++[<++++++>-]<..>+++++++++[<--------->-]<--.>+++++++[< ++++++++++>-]<+++.+++++++++++.>++++++++[<----------->-]<++++ .>+++++[<+++++++++++++>-]<.>+++[<++++++>-]<-.---.++++++.---- ---.----------.>++++++++[<----------->-]<+.---.[-]<<<->[-]>[ -]<<[>+>+<<-]>>[<<+>>-]>>>[-]<<<+++++++++<[>>>+<<[>+>[-]<<-] >[<+>-]>[<<++++++++++>>>+<-]<<-<-]+++++++++>[<->-]>>+>[<[-]< <+>>>-]>[-]+<<[>+>-<<-]<<<[>>+>+<<<-]>>>[<<<+>>>-]<>>[<+>-]< <-[>[-]<[-]]>>+<[>[-]<-]<++++++++[<++++++<++++++>>-]>>>[>+>+ <<-]>>[<<+>>-]<[<<<<<.>>>>>-]<<<<<<.>>[-]>[-]++++[<++++++++> -]<.>++++[<++++++++>-]<++.>+++++[<+++++++++>-]<.><+++++..--- -----.-------.>>[>>+>+<<<-]>>>[<<<+>>>-]<[<<<<++++++++++++++ .>>>>-]<<<<[-]>++++[<++++++++>-]<.>+++++++++[<+++++++++>-]<- -.---------.>+++++++[<---------->-]<.>++++++[<+++++++++++>-] <.+++..+++++++++++++.>++++++++[<---------->-]<--.>+++++++++[ <+++++++++>-]<--.-.>++++++++[<---------->-]<++.>++++++++[<++ ++++++++>-]<++++.------------.---.>+++++++[<---------->-]<+. >++++++++[<+++++++++++>-]<-.>++[<----------->-]<.+++++++++++ ..>+++++++++[<---------->-]<-----.---.+++.---.[-]<<<]

Now if you didn't know about this language before, you'll see where it gets its name. So what the f*** is all that code about eh? I figure it's something to do with pushes and pops, or shifts, or.... f*** knows.

Anyone met this curious language before?

I've seen it before... it's supposed to confuse dumb people and make them tell religious jokes that nobody laughs at...

Well if your brain survived that one, try this out, it's a language called Befunge:

Code:

----- begin beer.bf ----- v v0\1:\1:\0\0\!:p15-< Bottles of Beer for Befunge 0 \ {befunge} >" ekaT">v written by Brian Raiter, 5/97 0>>.0"llaw eht no "v<#,: [email protected] "\, >"eno"^>0 #"^1^_v c1,>51g#^_"ti"^. >vr : $ "::^" down, pass "^|\*25,<^ # i e ^g1< ,>052*":dnuor t"vbv:< v0_^ . , ^< " " >52*".ll"v >,^ fb e v"aw eht no r"v """ ,: >" ;"^ f ^<@ meo >^"bottle"< "o $ o m^"re:"52*^>"s"^v"les"<,: "^< ^"99 bott"< >^>^< >" yub ,erots eht ot oG"^ ------ end beer.bf ------

Notice that some of the strings are written backwards.

where exactly did you find these languages, they look like they were written by an expert panel of mental patients.

I found them here.

Hello Fox program actually!
nope, as i said, it does something more than that :)
Can be translated to visual smiley code too:

No idea ;) I hate these difficult languages... why can't you just use Orthogonal? :D

Hey, I just remembered this thread and thought I'd add another language that makes my ears bleed.... I hope yours do too. Enjoy! :)

INTERCAL

Ever heard of a language called Intercal?

Every statement must start with the phrase PLEASE !

Otherwise the error message generated is "The programmer is insufficiently polite"..

Smart ?

INTERCAL 2

Heres a sample Intercal program

Code:

DO (5) NEXT (5) DO FORGET #1 PLEASE WRITE IN :1 DO .1 <- '?":1~'#32768$#0'"$#1'~#3 DO (1) NEXT DO :1 <- "'?":1~'#65535$#0'"$#65535' ~'#0$#65535'"$"'?":1~'#0$#65535'" $#65535'~'#0$#65535'" DO :2 <- #1 PLEASE DO (4) NEXT (4) DO FORGET #1 DO .1 <- "?':1~:2'$#1"~#3 DO :1 <- "'?":1~'#65535$#0'"$":2~'#65535 $#0'"'~'#0$#65535'"$"'?":1~'#0 $#65535'"$":2~'#0$#65535'"'~'#0$#65535'" DO (1) NEXT DO :2 <- ":2~'#0$#65535'" $"'":2~'#65535$#0'"$#0'~'#32767$#1'" DO (4) NEXT (2) DO RESUME .1 (1) PLEASE DO (2) NEXT PLEASE FORGET #1 DO READ OUT :1 PLEASE DO .1 <- '?"':1~:1'~#1"$#1'~#3 DO (3) NEXT PLEASE DO (5) NEXT (3) DO (2) NEXT PLEASE GIVE UP

Note the last line (he he)

Here is an excerpt from its manual...

Quote:

2.2 Uses for INTERCAL
INTERCAL's main advantage over other programming languages is its strict simplicity. It has few capabilities, and thus there are few restrictions to be kept in mind. Since it is an exceedingly easy language to learn, one might expect it would be a good language for initiating novice programmers. Perhaps surprising, than, is the fact that it would be more likely to initiate a novice into a search for another line of work. As it turns out, INTERCAL is more useful (which isn't saying much) as a challenge to professional programmers.

Want to know more about Intercal? You just need to post a reply!! :)

befunge

took me an hour to make this befunge app:

Code:

v >*"namadek"v 2 5 v,_v#<:< < 5 2 >:^$ * 0 v< >"eb"^ >1|:-1<|:<^"fung"< >0"!!!looc s'e"^ @

guess what this does?

Does it print "Kedaman" to the screen?
Mar 1st, 2001, 09:28 AM
kedaman

yep, but it does more than that :)

Code:

v v v v?<?>?v 12 v 56 v<3?4>v >.@^@.< ? v @# ? 1v4 ? 2v5 ?3v6 >^^^ vvvvv.

i wrote two other apps just for the fun of it, they do the exact same thing though.

the last one has a bug, it should be

Code:

? vv @# ? 1v4 ? 2v5 ## ?3v6 >v .

and now it's the most compact one too :)

Where did you learn to write that?!? :confused:

I looked up befunge on altavista and found some source, forgot to bookmark it though, befunge is really cool once you learn it :p
the sixth and last version of befungdice i made looks like this:

Code:

?1v>#3v# >5>?1+>.@

yep it prints a random number from 1 to 6
