Answer 1

Perl (410 characters)

There's already a website dedicated to this contest:

One of the Perl solutions would be very very hard to beat in terms of creativity, it reads:

[bottles.pl]

         $a=
        "cpuu
       \bmft p
       \bg cff
       \bs";$b
       ="po ui
       \bf xbm
      \bm";$c="
      Ypv ublf p
     \bof epxo qb
   \btt ju bspvoe";
  $a =~ s/\n//;$a =~
  s/\s+/ /g; $b   =~
  s/\n// ;  $b    =~
  s/\s+/ /g;$c    =~
  s/\n// ;  $c    =~
  s/\s+/ /g;$a    =~
  y/b-z/a-z/;$b   =~
  tr/b-z/a-z/;$c  =~
  tr/b-z/a-z/ ; for(
  $d=100;$d>0;$d--){
  print"$d $a $b $d"
  ;print" $a,\n$c, "
  ;print($d-1);print
  " $a $b.\n";} $x =
  "cjc"; $y="dobbz";
  $z="com";print"\n"
  ;print "- $x\@$y."
   ;print"$z \n\n";

Brainf*** (1,509)

I figured I could trump this answer by not only making 9 beer bottles instead of 1, but also by only using 7 different characters in the code.

I do have to admit though, there is a bug in the code (maybe you can figure out how to fix it for me?) and it does not print the final sentence, Go to the store and buy some more, 99 bottles of beer on the wall. But other than that, it functions just as well as any of the programs made in those sissy programming languages everyone else seems to like to use.

Who said C# had too much ceremony? Whoever it was, they have never been so right.

using System.Linq;
using System.Text;

namespace _99Bottles
{
    class Program
    {
        static void Main(string[] args)
        {
            PrintSong(99);
        }

        static void PrintSong(int bottleCount)
        {
            Func<int, string> sOrBlank = howMany => howMany > 1 ? "s" : "";

            PrintBottles(howManyBottles =>

Answer 7

Definitely doesn't qualify as creative, but it gets'r done from the command line with a single command.

perl -e '$i=99;while($i>1){print("$i bottles of beer on the wall, $i bottles of beer.\nTake one down and pass it around, ".--$i." bottles of beer on the wall\n\n");}print("1 bottle of beer on the wall, 1 bottle of beer.\nGo to the store and buy some more, 99 bottles of beer on the wall.\n");'

Answer 10

Windows PowerShell (186)

filter b{"$_ bottle$('s'*!!--$_) of beer"}(99..1|%{($_|b)+" on the wall, $($_|b)."
"Take one down and pass it around, $(--$_|b).
"})[0..196]
"Go to the store and buy some more, $(99|b)."

Fairly straightforward.

I'm using a filter for the bottles of beer, since function is longer and invocation needs parentheses in any case. The plural detection (!!--$_) first decrements the number of bottles by one (so plural is anything non-zero), casts it to boolean and negates it with the first ! and negates it again so we now have a boolean describing whether the number needs a plural or not. This is then implicitly casted to an integer when multiplying the string.

Inline line breaks are fun.

Spawning more lines than needed and cutting back afterwards, too.

Answer 13

Javascript (285)

This assumes there is a function called print, to output a string.

b=' of beer on the wall';n=100;while(--n>1)if(n>1)print(n+" bottles"+b+', '+n+" bottles of beer.\nTake one down and pass it around, "+(n-1)+' bottle'+(n-1>1?'s':'')+b+'.\n\n');print("1 bottle"+b+", 1 bottle of beer.\nGo to the store and buy some more, 99 bottles of beer on the wall.")

Answer 14

PHP: 285 240 233 231 Characters

$i=99;$b=" bottles of beer";$o=" bottle of beer";$c=" on the wall";while($i>1){echo"$i$b$c, $i$b.\nTake one down and pass it around, ".--$i.(($i>1)?$b:$o).$c.".\n\n";}echo"$i$o$c, $i$o.\nGo to the store and buy some more, 99$b$c.";

Answer 15

JavaScript (216 228 215)

for(a=99,c=" on the wall";a;)document.write((d=eval(b="(a||99)+' bottle'+(a-1?'s':'')+' of beer'"))+c+", "+d+".<br>"+(--a?"Take one down and pass it around, ":"Go to the store and buy some more, ")+eval(b)+c+".<p>")

Edit: Had a single "1 bottles of beer" in initial version, 3rd version is completely rewritten, notice cool tricks like (a||99) to get 99 in the last line, (a-1?'s':'') making plural for every case but a==1 though without need for the wasteful ==, and setting the value of b inside a statement where it is used.

Still pretty new to Ruby, really just playing around

o =" bottles of beer";w=" on the wall";t="Take one down and pass it around, ";s=" bottle of beer"
99.downto(3){|b|puts"#{b}#{o+w}, #{b}#{o}.\n#{t}#{b-1}#{o+w}.\n\n"}
puts"2 #{o+w}, 2 #{o}.\n#{t}1#{s}#{w}.\n\n1#{s+w}, 1#{s}.\nGo to the store and buy some more, 99#{o+w}."

Answer 19

Scheme (270)

No whitespace:

(let l((i 99))(let((b" bottle")(c" on the wall")(d"Take one down and pass it around,")(e".\n")(f", ")(g" of beer"))(if(= i 1)(map display`(1,b,g,c,f,1,b,g,e"Go to the store and buy some more, 99",b,c,e))(begin(map display`(,i,b,g,c,f,i,b,e,d,i,b,c,e"\n"))(l(-1+ i))))))

With whitespace:

    (let l ((i 99))
      (let ((b" bottle")
            (c" on the wall")
            (d"Take one down and pass it around, ")
            (e".\n")
            (f", ")
            (g" of beer"))
        (if (= i 1)
            (map display`(1 ,b ,g ,c ,f ,1 ,b ,g ,e
                          "Go to the store and buy some more, 99" ,b ,c ,e))
            (begin (map display `(,i ,b ,g ,c ,f ,i ,b ,e ,d ,i ,b ,c ,e "\n"))
                   (l (-1+ i))))))

I found this way of making a Python program shorter :)

Answer 21

C#

Not intended to be short, but perhaps this counts as creative?

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        Console.WriteLine(string.Join(Environment.NewLine, Enumerable.Range(0, 100).Select(i =>
            string.Format(
                string.Format(
                    "{0} {1} {{3}} {{4}},{{9}}{0} {1} {{3}}.{{9}}{2},{{9}}{3} {4} {{3}} {{4}}.{{9}}",
                    i == 99 ? "{0}" : "{7}",
                    i == 98 ? "{1}" : "{2}",
                    i == 99 ? "{6}" : "{5}",
                    i == 98 ? "{0}" : "{8}",
                    i == 97 ? "{1}" : "{2}"
                ),
                "No",
                "bottle",
                "bottles",
                "of beer",
                "on the wall",
                "Take one down, pass it around",
                "Go to the store, buy some more",
                99 - i,
                (198 - i) % 100,
                Environment.NewLine
        ))));
    }
}

Note this is just a single statement :)

";echo"1".$b.$c.", 1".$b.".
Go to the store and buy some more, 99".$a.$c.".";

I hope I'll compress some more tomorrow.

Answer 25

JavaScript (7 functions)

Not golfed. This is intended as a (mostly) functional implementation of the song.

function firstUpper(s) {
    return s.slice(0, 1).toUpperCase() + s.slice(1);
}

function bottles(x) {
    return (x || "no more") + " " + (x == 1 ? "bottle" : "bottles") + " of beer";
}

function wall(x) {
    return bottles(x) + " on the wall";
}

function line1(x) {
    return wall(x) + ", " + bottles(x) + ".";
}

function line2(x, max) {
     return (x ? "take one down and pass it around, " + wall(x - 1) : "go to the store and buy some more, " + wall(max)) + ".";
}

function verse(x, max) {
    return [line1(x), line2(x, max)].map(firstUpper).join("\n") + "\n\n";
}


function song(max) {
    var text = "";
    for(var x = max; x >= 0; x--) {
        text += verse(x, max);
    }
    return text;
}

print(song(99));

Instead of using the third section in a for loop, it decreases the number on the fly when it is determining what string it needs to print out.

Could probably shave a few characters off, this was just a first try. :)

Here's equivalent Rebol which has the shorthand boiled out. Without any non-necessary whitespace, it would be 223 chars...still pretty competitive especially considering the clarity:

m: n: 99

b: does [
    rejoin [n { bottle} either n > 1 [{s}][{}] { of beer}]
]

loop n [
    print rejoin [
        b w: { on the wall} c: {, } b p: {.^/}

        either -- n > 1 [
            {Take one down, and pass it around}
        ] [
            n: m
            {Go to the store and buy some more}
        ]

        c b w p
    ]

Answer 29

PHP (249 chars)

My first golf attempt. It's kinda messy but that was to "fix" my problem with singular/plural in the the third last line of the song.

<?
$l=" on the wall";
$m=" of beer";
$x=" bottles";
for($i=99;$i>=1;$i--){
    $o="$i$x$m$l, $i$x$m.\n";
    $x=($i<3)?" bottle":$x;$o.=($i==1)?"Go to the store and buy some more, 99 
    bottles$m$l.":"Take one down and pass it around, ".($i-1)."$x$m$l.\n\n";
    echo$o;
}

No spaces

<?$l=" on the wall";$m=" of beer";$x=" bottles";for($i=99;$i>=1;$i--){$o="$i$x$m$l, $i$x$m.\n";$x=($i<3)?" bottle":$x;$o.=($i==1)?"Go to the store and buy some more, 99 bottles$m$l.":"Take one down and pass it around, ".($i-1)."$x$m$l.\n\n";echo$o;}

I also want to optimise it more later.

Answer 30

PHP (191)

Short tags must be turned on for this to work.

<? eval(gzinflate("]Á\nÂ0De*´ÅkPþ€Ç^»¥Á6+MJñß\rUAzYØÇììŒ4‡†Cȃ;¢)S2&Ê¡'D=™êxÚH{¨k%íq—FQlŸtíi¯NBZidÌ¥)wÑ7Jׄ–£ƒv-îÚ{Ø\0=ñìÚu’6NìEõ\rðûŸ|°fI{f^\"ùÀ-Æf~ÀóHÉQ×ë.ÿ-J¡^o"));?>

For those who are curious, here's what the gzinflate() returns:

$b=' bottles of beer';$w=' on the wall';for($i=99;$i>0;$i--){echo $i>1?"$i$b$w,$b.\nTake one down and pass it around, $i$b$w.\n\n":"1 bottle of beer$w, 1 bottle of beer.\nGo to the store and buy some more, 99 bottles of beer on the wall.";}

Broken down (with a few tweaks), that's:

$b=' bottles of beer';
$w=' on the wall';
for($i=99;$i>0;$i--){
   if ($i>1) {
      echo "$i$b$w,$b.\nTake one down and pass it around, $i$b$w.\n\n";
   } else {
      echo "1 bottle of beer$w, 1 bottle of beer.\nGo to the store and buy some more, 99 bottles of beer on the wall.";
   }
}

Oddly enough, my original attempt involved using gzinflate() on the inside for the final iteration, but once you encode it again for the eval() it makes it larger than had it not been there.
