You are encouraged to solve this task according to the task description, using any language you may know.
Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". [1]
FizzBuzz was presented as the lowest level of comprehension required to illustrate adequacy. [2]
ActionScript
The ActionScript solution works just like the JavaScript solution (they share the ECMAScript specification). The difference is that ActionScript has the trace command to write out to a console.
<lang actionscript> for (var i:int = 1; i <= 100; i++) {
if (i % 15 == 0) trace('FizzBuzz'); else if (i % 5 == 0) trace('Buzz'); else if (i % 3 == 0) trace('Fizz'); else trace(i);
} </lang>
AutoIt
<lang AutoIt> For $i = 1 To 100 If Mod($i, 15) = 0 Then MsgBox(0, "FizzBuzz", "FizzBuzz") ElseIf Mod($i, 5) = 0 Then MsgBox(0, "FizzBuzz", "Buzz") ElseIf Mod($i, 3) = 0 Then MsgBox(0, "FizzBuzz", "Fizz") Else MsgBox(0, "FizzBuzz", $i) EndIf Next </lang>
8086 Assembly
Assembly programs that output a number on the screen are programmable in two ways: calculating the number in binary to convert it next in ASCII for output, or keeping the number in Binary Coded Decimal (BCD) notation to speed up the output to the screen, because no binary to decimal conversion needs to be applied. The first approach is the most useful because the binary number is immediately recognizable to the computer, but, in a problem where the calculations are very few and simple and the final result is mainly text on the screen, using binary numbers would speed up calculations, but will greatly slow down the output.
The BCD used is based on the ASCII text encoding: zero is the hexadecimal byte 30, and nine is the hexadecimal byte 39. The BCD number is kept in the DX register, the most significant digit in DH and the less significant digit in DL. See the comments for further explaining of the program's structure, wich is meant for speed and compactness rather than modularity: there are no subroutines reusable in another program without being edited.
This program is 102 bytes big when assembled. The program is written to be run in an IBM PC because the 8086 processor alone does not provide circuitry for any kind of direct screen output. At least, I should point out that this program is a little bugged: the biggest number representable with the BCD system chosen is 99, but the last number displayed is 100, wich would be written as :0 because the program does provide overflow detecting only for the units, not for tens (39 hex + 1 is 3A, that is the colon symbol in ASCII). However, this bug is hidden by the fact that the number 100 is a multiple of five, so the number is never displayed, because it is replaced by the string "buzz". <lang asm> ; Init the registers mov dx,03030h ; For easier printing, the number is
;kept in Binary Coded Decimal, in
;the DX register.
mov ah,0Eh ; 0Eh is the IBM PC interrupt 10h
;function that does write text on ;the screen in teletype mode.
mov bl,100d ; BL is the counter (100 numbers). xor cx,cx ; CX is a counter that will be used
;for screen printing.
xor bh,bh ; BH is the counter for counting
;multiples of three.
writeloop: ; Increment the BCD number in DX. inc dl ; Increment the low digit cmp dl,3Ah ; If it does not overflow nine, jnz writeloop1 ;continue with the program, mov dl,30h ;otherwise reset it to zero and inc dh ;increment the high digit writeloop1: inc bh ; Increment the BH counter. cmp bh,03h ; If it reached three, we did
;increment the number three times ;from the last time the number was ;a multiple of three, so the number ;is now a multiple of three now,
jz writefizz ;then we need to write "fizz" on the
;screen.
cmp dl,30h ; The number isn't a multiple of jz writebuzz ;three, so we check if it's a cmp dl,35h ;multiple of five. If it is, we jz writebuzz ;need to write "buzz". The program
;checks if the last digit is zero or ;five.
mov al,dh ; If we're here, there's no need to int 10h ;write neither "fizz" nor "buzz", so mov al,dl ;the program writes the BCD number int 10h ;in DX writespace: mov al,020h ;and a white space. int 10h dec bl ; Loop if we didn't process 100 jnz writeloop ;numbers.
programend: ; When we did reach 100 numbers, cli ;the program flow falls here, where hlt ;interrupts are cleared and the jmp programend ;program is stopped.
writefizz: ; There's need to write "fizz": mov si,offset fizz ; SI points to the "fizz" string, call write ;that is written on the screen. xor bh,bh ; BH, the counter for computing the
;multiples of three, is cleared.
cmp dl,30h ; We did write "fizz", but, if the jz writebuzz ;number is a multiple of five, we cmp dl,35h ;could need to write "buzz" also: jnz writespace ;check if the number is multiple of
;five. If not, write a space and ;return to the main loop.
writebuzz: ; (The above code falls here if
;the last digit is five, otherwise ;it jumps)
mov si,offset buzz ;SI points to the "buzz" string, call write ;that is written on the screen. jmp writespace ; Write a space to return to the main
;loop.
write: ; Write subroutine: mov cl,04h ; Set CX to the lenght of the string:
;both strings are 4 bytes long.
write1: mov al,[si] ; Load the character to write in AL. inc si ; Increment the counter SI. int 10h ; Call interrupt 10h, function 0Eh to
;write the character and advance the ;text cursor (teletype mode)

C
<lang c>#include<stdio.h>
int main (void) {
int i; for (i = 1; i <= 100; i++) { if (!(i % 3)) printf ("Fizz"); else if (!(i % 5)) printf ("Buzz"); else printf ("%d", i);
printf("\n"); } return 0;
}</lang>
obfuscated:
<lang c>
- include <stdio.h>
- define F(x,y) printf("%s",i%x?"":#y"zz")
int main(int i){for(--i;i++^100;puts(""))F(3,Fi)|F(5,Bu)||printf("%i",i);return 0;}</lang>
This actually works (the array init part, saves 6 bytes of static data, whee):<lang c>#include<stdio.h>
int main () { int i; char *s[] = { "%d\n", "Fizz\n", s[3] + 4, "FizzBuzz\n" }; for (i = 1; i <= 100; i++) printf(s[!(i % 3) + 2 * !(i % 5)], i);
return 0; }</lang>
C++
<lang cpp>#include <iostream>
using namespace std; int main () {
int i; for (i = 0; i <= 100; i++) { if ((i % 15) == 0) cout << "FizzBuzz" << endl; else if ((i % 3) == 0) cout << "Fizz" << endl; else if ((i % 5) == 0) cout << "Buzz" << endl; else cout << i << endl; } return 0;
}</lang>
Alternate version not using modulo 15: <lang cpp>#include <iostream> using namespace std;
int main() {
for (int i = 0; i <= 100; ++i) { bool fizz = (i % 3) == 0; bool buzz = (i % 5) == 0; if (fizz) cout << "Fizz"; if (buzz) cout << "Buzz"; if (!fizz && !buzz) cout << i; cout << endl; }
}</lang>
Another alternate version using functions and no modulo 15: <lang cpp>
- include <iostream>
bool special(int i, int factor, char const* word) {
if (i % factor == 0) { std::cout << word; return true; } else return false;
}
int main() {
for (int i = 0; i <= 100; ++i) { if (!(special(i, 3, "Fizz") | special(i, 5, "Buzz"))) // note: binary or, not logical or! (No short circuit) std::cout << i; std::cout << std::endl; }
} </lang>
Version computing FizzBuzz at compile time with metaprogramming: <lang cpp>#include <iostream>
template <int n, int m3, int m5> struct fizzbuzz : fizzbuzz<n-1, (n-1)%3, (n-1)%5> {
fizzbuzz() { std::cout << n << std::endl; }
};
template <int n> struct fizzbuzz<n, 0, 0> : fizzbuzz<n-1, (n-1)%3, (n-1)%5> {

template <int n, int p> struct fizzbuzz<n, 0, p> : fizzbuzz<n-1, (n-1)%3, (n-1)%5> {
fizzbuzz() { std::cout << "Fizz" << std::endl; }
};
template <int n, int p> struct fizzbuzz<n, p, 0> : fizzbuzz<n-1, (n-1)%3, (n-1)%5> {
fizzbuzz() { std::cout << "Buzz" << std::endl; }
};
template <> struct fizzbuzz<0,0,0> {
fizzbuzz() { std::cout << 0 << std::endl; }

This was clearly a challenge in a language without a modulus operator, a proper if statement except for checking if a variable is not exactly 0, and no way to define text except 1 character at a time on a stack.

Fortran
In ANSI FORTRAN 77 or later use structured IF-THEN-ELSE (example uses some ISO Fortran 90 features): <lang fortran>program fizzbuzz_if
integer :: i do i = 1, 100 if (mod(i,15) == 0) then; print *, 'FizzBuzz' else if (mod(i,3) == 0) then; print *, 'Fizz' else if (mod(i,5) == 0) then; print *, 'Buzz' else; print *, i end if end do
end program fizzbuzz_if</lang>
In ISO Fortran 90 or later use SELECT-CASE statement: <lang fortran>program fizzbuzz_select
integer :: i do i = 1, 100 select case (mod(i,15)) case 0; print *, 'FizzBuzz' case 3,6,9,12; print *, 'Fizz' case 5,10; print *, 'Buzz' case default; print *, i end select end do end program fizzbuzz_select</lang>

One liner version (I added new lines to better readability but when you omit them it's one liner): <lang gosu>// note that compiler reports error (I don't know why) but still it's working for (i in 1..100) {

fizzbuzz x
| x `mod` 15 == 0 = "FizzBuzz" | x `mod` 3 == 0 = "Fizz" | x `mod` 5 == 0 = "Buzz" | otherwise = show x
</lang>
Alternate implementation using lazy infinite lists and avoiding use of "mod":
<lang haskell> main = mapM_ putStrLn $ take 100 fizzbuzz
fizzbuzz = zipWith (\x y -> if null y then show x else y) [1..] fbs
fbs = zipWith (++) (cycle ["","","Fizz"]) (cycle ["","","","","Buzz"]) </lang>

Io
Here's one way to do it:
<lang io>for(a,1,100,

)</lang>
And here's a port of the Ruby version, which I personally prefer:
<lang io>a := 0; b := 0 for(n, 1, 100,
if(a = (n % 3) == 0, "Fizz" print); if(b = (n % 5) == 0, "Buzz" print); if(a not and b not, n print); "\n" print
)</lang>
And here is another more idiomatic version:
<lang Io>for (n, 1, 100,
fb := list ( if (n % 3 == 0, "Fizz"), if (n % 5 == 0, "Buzz")) select (isTrue) if (fb isEmpty, n, fb join) println

There are more sophisticated solutions to this task, but in the spirit of "lowest level of comprehension required to illustrate adequacy" this is what one might expect from a novice programmer (with a little variation in how the strings are stored and displayed).
<lang MATLAB>function fizzBuzz()
for i = (1:100) if mod(i,3) == 0 fprintf('Fizz') end if mod(i,5) == 0 fprintf('Buzz') end
if not((mod(i,3) == 0) || (mod(i,5) == 0)) fprintf(num2str(i)) end fprintf(' ') end fprintf('\n');

Perl 6
Most straightforwardly:
<lang perl6>for 1 .. 100 {
when $_ %% (3 & 5) { say 'FizzBuzz'; } when $_ %% 3 { say 'Fizz'; } when $_ %% 5 { say 'Buzz'; } default { .say; }
}</lang>
Most concisely:
<lang perl6>say 'Fizz' x $_ %% 3 ~ 'Buzz' x $_ %% 5 || $_ for 1 .. 100;</lang>
And here's an implementation that never checks for divisibility:
<lang perl6>.say for
(( xx 2, 'Fizz') xx * Z~ ( xx 4, 'Buzz') xx *) Z|| 1 .. 100;</lang>
PHP
if/else ladder approach
<lang php><?php for ($i = 1; $i <= 100; $i++) {
if (!($i % 15)) echo "FizzBuzz\n"; else if (!($i % 3)) echo "Fizz\n"; else if (!($i % 5)) echo "Buzz\n"; else echo "$i\n";
} ?></lang>
concatenation approach
Uses PHP's concatenation operator (.=) to build the output string. The concatenation operator allows us to add data to the end of a string without overwriting the whole string. Since Buzz will always appear if our number is divisible by five, and Buzz is the second part of "FizzBuzz", we can simply append "Buzz" to our string.
In contrast to the if-else ladder, this method lets us skip the check to see if $i is divisible by both 3 and 5 (i.e. 15). However, we get the added complexity of needing to reset $str to an empty string (not necessary in some other languages), and we also need a separate if statement to check to see if our string is empty, so we know if $i was not divisible by 3 or 5.
<lang php><?php for ( $i = 1; $i <= 100; ++$i ) {
$str = "";
if (!($i % 3 ) ) $str .= "Fizz";
if (!($i % 5 ) ) $str .= "Buzz";
if ( empty( $str ) ) $str = $i;
echo $str . "\n";
} ?></lang>
One Liner Approach
<lang php> <?php for($i = 1; $i <= 100 and print(($i % 15 ? $i % 5 ? $i % 3 ? $i : 'Fizz' : 'Buzz' : 'FizzBuzz') . "\n"); ++$i); </lang>
PicoLisp
We could simply use 'at' here: <lang PicoLisp>(for N 100
(prinl (or (pack (at (0 . 3) "Fizz") (at (0 . 5) "Buzz")) N) ) )</lang>
Or do it the standard way: <lang PicoLisp>(for N 100
(prinl (cond ((=0 (% N 15)) "FizzBuzz") ((=0 (% N 3)) "Fizz") ((=0 (% N 5)) "Buzz") (T N) ) ) )</lang>

Prolog
Maybe not the most conventional way to write this in Prolog. The fizzbuzz predicate uses a higher-order predicate and print_item uses the if-then-else construction.
<lang prolog>fizzbuzz :-
foreach(between(1, 100, X), print_item(X)).
print_item(X) :-
( 0 is X mod 15 -> print('FizzBuzz') ; 0 is X mod 3 -> print('Fizz') ; 0 is X mod 5 -> print('Buzz') ; print(X) ), nl.</lang>
More conventional:
<lang prolog> fizzbuzz(X) :- 0 is X mod 15, write('FizzBuzz'). fizzbuzz(X) :- 0 is X mod 3, write('Fizz'). fizzbuzz(X) :- 0 is X mod 5, write('Buzz'). fizzbuzz(X) :- write(X).
dofizzbuzz :- foreach(between(1, 100, X), (fizzbuzz(X),nl)). </lang>

And a shorter, but less clear version, using a list comprehension and logical expressions: <lang python>for i in range(1, 101):

c = acc & 3 print messages[c] if c else i acc = acc >> 2 | c << 28</lang>

Or, (ab)using the vector recycling rule,
<lang R>x <- paste(rep("", 100), c("", "", "Fizz"), c("", "", "", "", "Buzz"), sep="") cat(ifelse(x == "", 1:100, x), "\n")</lang>

<lang REBOL>REBOL [ Title: "FizzBuzz" Author: oofoe Date: 2009-12-10 URL: http://rosettacode.org/wiki/FizzBuzz ]
- Concatenative. Note use of 'case/all' construct to evaluate all
- conditions. I use 'copy' to allocate a new string each time through
- the loop -- otherwise 'x' would get very long...
repeat i 100 [ x: copy "" case/all [ 0 = mod i 3 [append x "Fizz"] 0 = mod i 5 [append x "Buzz"] "" = x [x: mold i] ] print x ]</lang>
Here are two examples by Nick Antonaccio.

Retro
This is a port of some Forth code.
<lang Retro>: fizz? ( s-f ) 3 mod 0 = ;
- buzz? ( s-f ) 5 mod 0 = ;

- ?num ( s- ) num? &putn &drop if ;
- fizzbuzz ( s- ) dup ?fizz dup ?buzz dup ?num space ;
- all ( - ) 100 [ 1+ fizzbuzz ] iter ;</lang>
It's cleaner to use quotes and combinators though:

Smalltalk
Since only GNU Smalltalk supports file-based programming, we'll be using its syntax.
<lang smalltalk>Integer extend [
fizzbuzz [ | fb | fb := '%<Fizz|>1%<Buzz|>2' % { self \\ 3 == 0. self \\ 5 == 0 }. ^fb isEmpty ifTrue: [ self ] ifFalse: [ fb ] ]
] 1 to: 100 do: [ :i | i fizzbuzz displayNl ]</lang>
A Squeak/Pharo example using the Transcript window: <lang smalltalk>(1 to: 100) do: [:n | ((n \\ 3)*(n \\ 5)) isZero
ifFalse: [Transcript show: n].
(n \\ 3) isZero ifTrue: [Transcript show: 'Fizz']. (n \\ 5) isZero ifTrue: [Transcript show: 'Buzz']. Transcript cr.]</lang>
The Squeak/Pharo examples below present possibilities using the powerful classes available. In this example, the dictionary can have as keys pairs of booleans and in the interaction the several boolean patterns select the string to be printed or if the pattern is not found the number itself is printed.
<lang smalltalk>fizzbuzz := Dictionary with: #(true true)->'FizzBuzz'
with: #(true false)->'Fizz' with: #(false true)->'Buzz'.
1 to: 100 do: [ :i | Transcript show:
(fizzbuzz at: {i isDivisibleBy: 3. i isDivisibleBy: 5}
ifAbsent: [ i ]); cr]</lang>
Smalltalk does not have a case-select construct, but a similar effect can be attained using a collection and the #includes: method:
<lang smalltalk>1 to: 100 do: [:n | |r| r := n rem: 15. Transcript show: (r isZero ifTrue:['fizzbuzz'] ifFalse: [(#(3 6 9 12) includes: r) ifTrue:['fizz'] ifFalse:[((#(5 10) includes: r)) ifTrue:['buzz'] ifFalse:[n]]]); cr].</lang>
If the construction of the whole collection is done beforehand, Smalltalk provides a straightforward way of doing because collections can be heterogeneous (may contain any object):
<lang smalltalk>fbz := (1 to: 100) asOrderedCollection.
3 to: 100 by: 3 do: [:i | fbz at: i put: 'Fizz']. 5 to: 100 by: 5 do: [:i | fbz at: i put: 'Buzz'].
15 to: 100 by: 15 do: [:i | fbz at: i put: 'FizzBuzz']. fbz do: [:i | Transcript show: i; cr].</lang>
The approach building a dynamic string can be done as well:
<lang smalltalk>1 to: 100 do: [:i | |fb s| fb := {i isDivisibleBy: 3. i isDivisibleBy: 5. nil}. fb at: 3 put: (fb first | fb second) not. s := '<1?Fizz:><2?Buzz:><3?{1}:>' format: {i printString}. Transcript show: (s expandMacrosWithArguments: fb); cr].</lang>

<lang sql> DROP TABLE fizzbuzz; CREATE TABLE fizzbuzz(i int, fizz string, buzz string); INSERT INTO fizzbuzz VALUES(1,"",""); INSERT INTO fizzbuzz SELECT i + (SELECT max(i) FROM fizzbuzz), fizz, buzz FROM fizzbuzz; INSERT INTO fizzbuzz SELECT i + (SELECT max(i) FROM fizzbuzz), fizz, buzz FROM fizzbuzz; INSERT INTO fizzbuzz SELECT i + (SELECT max(i) FROM fizzbuzz), fizz, buzz FROM fizzbuzz; INSERT INTO fizzbuzz SELECT i + (SELECT max(i) FROM fizzbuzz), fizz, buzz FROM fizzbuzz; INSERT INTO fizzbuzz SELECT i + (SELECT max(i) FROM fizzbuzz), fizz, buzz FROM fizzbuzz; INSERT INTO fizzbuzz SELECT i + (SELECT max(i) FROM fizzbuzz), fizz, buzz FROM fizzbuzz; INSERT INTO fizzbuzz SELECT i + (SELECT max(i) FROM fizzbuzz), fizz, buzz FROM fizzbuzz; DROP TABLE lookup; CREATE TABLE lookup (fizzy, buzzy, rem); INSERT INTO lookup VALUES("fizz", "buzz", 1); SELECT

</lang>
Alternate solution by Daniel Lyons (PostgreSQL specific):
<lang sql> SELECT i, fizzbuzz
FROM (SELECT i, CASE WHEN i % 15 = 0 THEN 'FizzBuzz' WHEN i % 5 = 0 THEN 'Buzz' WHEN i % 3 = 0 THEN 'Fizz' ELSE NULL END AS fizzbuzz FROM generate_series(1,100) AS i) AS fb WHERE fizzbuzz IS NOT NULL;
</lang>
Oracle SQL: <lang sql>select (CASE
WHEN MOD(lvl,15)=0 THEN 'FizzBuzz' WHEN MOD(lvl,3)=0 THEN 'Fizz' WHEN MOD(lvl,5)=0 THEN 'Buzz' ELSE TO_CHAR(lvl) END) FizzBuzz
from (
select LEVEL lvl from dual connect by LEVEL <= 100)</lang>
Another alternative solution based on recursive Common Table Expressions (MSSQL 2005+):
<lang sql> WITH nums (n, fizzbuzz ) AS ( SELECT 1, CONVERT(nvarchar, 1) UNION ALL SELECT (n + 1) as n1, CASE WHEN (n + 1) % 15 = 0 THEN 'FizzBuzz' WHEN (n + 1) % 3 = 0 THEN 'Fizz' WHEN (n + 1) % 5 = 0 THEN 'Buzz' ELSE CONVERT(nvarchar, (n + 1)) END FROM nums WHERE n < 100 ) SELECT n, fizzbuzz FROM nums ORDER BY n ASC OPTION ( MAXRECURSION 100 ) </lang>
Here is the Oracle PL/SQL solution: <lang sql> declare
v_count integer;
begin
for v_count in 1..100 loop if(mod(v_count, 15) = 0) then dbms_output.put_line('Fizz Buzz'); elsif(mod(v_count, 3) = 0) then dbms_output.put_line('Fizz'); elsif(mod(v_count, 5) = 0) then dbms_output.put_line('Buzz'); else dbms_output.put_line(v_count); end if; end loop;
end; </lang>
Standard ML
<lang sml>fun output x =
case (x mod 3 = 0, x mod 5 = 0) of (true , true ) => "FizzBuzz" | (true , false) => "Fizz" | (false, true ) => "Buzz" | (false, false) => Int.toString x
val () = let
fun aux i = if i <= 100 then (print (output i ^ "\n"); aux (i+1)) else ()
in

UNIX Shell
This solution should work with any Bourne-compatible shell. <lang bash>i=1 while expr $i '<=' 100 >/dev/null; do w=false expr $i % 3 = 0 >/dev/null && { printf Fizz; w=true; } expr $i % 5 = 0 >/dev/null && { printf Buzz; w=true; } if $w; then echo; else echo $i; fi i=`expr $i + 1` done</lang>
The other solutions work with fewer shells.
The next solution requires $(( )) arithmetic expansion, which is in every POSIX shell; but it also requires the seq(1) command which is not part of some systems. (If your system misses seq(1), but it has BSD jot(1), then change `seq 1 100` to `jot 100`.)
<lang bash>for n in `seq 1 100`; do
if [ $((n % 15)) = 0 ]; then echo FizzBuzz elif [ $((n % 3)) = 0 ]; then echo Fizz elif [ $((n % 5)) = 0 ]; then echo Buzz else echo $n fi
done</lang>
The next solution requires the (( )) command from the Korn Shell.
<lang bash>NUM=1 until ((NUM == 101)) ; do
if ((NUM % 15 == 0)) ; then echo FizzBuzz elif ((NUM % 3 == 0)) ; then echo Fizz elif ((NUM % 5 == 0)) ; then echo Buzz else echo "$NUM" fi ((NUM = NUM + 1))
done</lang>
A version using concatenation:
<lang bash>for ((n=1; n<=100; n++)) do
fb= [ $(( n % 3 )) -eq 0 ] && fb="${fb}Fizz" [ $(( n % 5 )) -eq 0 ] && fb="${fb}Buzz" [ -n "${fb}" ] && echo "${fb}" || echo "$n"
done</lang>
A version using some of the insane overkill of Bash 4:
<lang bash>command_not_found_handle () {
local Fizz=3 Buzz=5 [ $(( $2 % $1 )) -eq 0 ] && echo -n $1 && [ ${!1} -eq 3 ]
}
for i in {1..100} do
Fizz $i && ! Buzz $i || echo -n $i echo
done</lang>

Second try
(a compiler for fizzbuzz)
define a command that will generate a sequence <lang v>[seq [] swap dup [zero? not] [rolldown [dup] dip cons rollup pred] while pop pop].</lang>
create a quote that will return a quote that returns a quote if its argument is an integer (A HOF) <lang v>[check [N X F : [[integer?] [[X % zero?] [N F cons] if] if]] view].</lang>
Create a quote that will make sure that the above quote is applied correctly if given (Number Function) as arguments. <lang v>[func [[N F] : [dup N F check i] ] view map].</lang>
And apply it <lang v>100 seq [
[15 [pop 'fizzbuzz' puts]] [5 [pop 'buzz' puts]] [3 [pop 'fizz' puts]] [1 [puts]]] [func dup] step [i true] map pop</lang>
the first one is much better :)
VBScript
Implementation
The EEF does eager evaluation. I'm still trying to figure out a lazy evaluation method using Eval(). One day ...
In the meantime, converting that to VB6 would mean using VB6's IIF() which would run a tad faster.
<lang vb> 'using the IF/ELSEIF ladder function fb( n ) if n mod 15 = 0 then fb = "FizzBuzz" elseif n mod 5 = 0 then fb = "Fizz" elseif n mod 3 = 0 then fb = "Buzz" else fb = n end if end function
'the Mexican IF function eef( b, p1, p2 ) if b then eef = p1 else eef = p2 end if end function
'using the Mexican IF function fb2( n ) fb2 = eef( n mod 15 = 0, "FizzBuzz", eef( n mod 5 = 0, "Fizz", eef( n mod 3 = 0, "Buzz", n ) ) ) end function
</lang>
Invocation
<lang vb> for i = 1 to 16 wscript.stdout.write fb(i) & " " next wscript.echo
for i = 1 to 16 wscript.stdout.write fb2(i) & " " next wscript.echo
</lang>
Output
1 2 Buzz 4 Fizz Buzz 7 8 Buzz Fizz 11 Buzz 13 14 FizzBuzz 16 1 2 Buzz 4 Fizz Buzz 7 8 Buzz Fizz 11 Buzz 13 14 FizzBuzz 16
