1, 2, Fizz, 4, Buzz

Introduction

In our recent effort to collect catalogues of shortest solutions for standard programming exercises, here is PPCG's first ever vanilla FizzBuzz challenge. If you wish to see other catalogue challenges, there is "Hello World!" and "Is this number a prime?".

Challenge

Write a program that prints the decimal numbers from 1 to 100 inclusive. 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”.

Output

The output will be a list of numbers (and Fizzes, Buzzes and FizzBuzzes) separated by a newline (either \n or \r\n). A trailing newline is acceptable, but a leading newline is not. Apart from your choice of newline, the output should look exactly like this:

1

The only exception to this rule is constant output of your language's interpreter that cannot be suppressed, such as a greeting, ANSI color codes or indentation.

Further Rules

• This is not about finding the language with the shortest approach for playing FizzBuzz, this is about finding the shortest approach in every language. Therefore, no answer will be marked as accepted.

• Submissions are scored in bytes in an appropriate preexisting encoding, usually (but not necessarily) UTF-8. Some languages, like Folders, are a bit tricky to score--if in doubt, please ask on Meta.

• Nothing can be printed to STDERR.

• Unlike our usual rules, feel free to use a language (or language version) even if it's newer than this challenge. If anyone wants to abuse this by creating a language where the empty program generates FizzBuzz output, then congrats for paving the way for a very boring answer.

Note that there must be an interpreter so the submission can be tested. It is allowed (and even encouraged) to write this interpreter yourself for a previously unimplemented language.

• If your language of choice is a trivial variant of another (potentially more popular) language which already has an answer (think BASIC or SQL dialects, Unix shells or trivial Brainfuck derivatives like Alphuck and ???), consider adding a note to the existing answer that the same or a very similar solution is also the shortest in the other language.

• Because the output is fixed, you may hardcode the output (but this may not be the shortest option).

• You may use preexisting solutions, as long as you credit the original author of the program.

• Standard loopholes are otherwise disallowed.

As a side note, please don't downvote boring (but valid) answers in languages where there is not much to golf; these are still useful to this question as it tries to compile a catalogue as complete as possible. However, do primarily upvote answers in languages where the authors actually had to put effort into golfing the code.

• Nothing can be printed to STDERR. Is this true only when running, or also when compiling (assuming that is a separate step?) – AShelly Sep 24 '15 at 20:47
• @AShelly Only when running – Beta Decay Sep 24 '15 at 20:48
• I’m not sure I like the fact that you hardcoded the 100 into the challenge. That way, a program that just generates the expected output is a valid entry, but is not interesting for this challenge. I think the challenge should expect the program to input the number of items to output. – Timwi Sep 24 '15 at 23:28
• @Timwi While I agree that it would make it (only slightly) more interesting, I've very often seen FizzBuzz as strictly 1 to 100 (on Wikipedia and Rosetta Code, for example). If the goal is to have a "canonical" FB challenge, it makes sense. – Geobits Sep 25 '15 at 0:50

Finally got around to finishing this. I had written an ungolfed solution weeks ago, but wasn't entirely happy with it so I never actually golfed it. After revisiting it the other day, I found a way to simplify the ungolfed solution slightly, and while I think there might still be a better way to approach the problem in general, I decided to golf it this time. The current solution is far from optimal, and I think it should actually fit in side-length 6 instead of 7. I'll give this a go over the next days, and when I'm happy with the result will add a full explanation. JavaScript, 65 bytes for(i=0;i++<100;console.log((i%3?'':'Fizz')+(i%5?'':'Buzz')||i));  The shortest approach I've found yet. Perhaps there's a better one; suggestions are welcome.

As always nothing is, 1000001 minus 1000000;
And Putin is, 1000003 minus 1000000; great
Just as Trump is, 1000005 minus 1000000; even better
Also as America is, Putin times Trump; the best
Most importantly Ivanka is, 1000101 minus 1000000;
And believe me that Hillary is nothing
As long as, Hillary thinks less of Ivanka;:
China is friends with Hillary
Democrats are idiots like Hillary
Obama is in line with Hillary
As long as, China thinks its more than America;:
Make China, China minus America;!
As long as, Democrats fear more Trump;:
Make Democrats, Democrats minus Trump;!
As long as, Obama gets more arsenal against Putin;:
Make Obama, Obama minus Putin;!
If everybody thinks, America is China?;:
Say "FizzBuzz"!
Otherwise: if we ask, Democrats are Trump?;:
Say "Buzz"!
Otherwise: what if, Obama is Putin?;:
Say "Fizz"!
Otherwise do this: tell Hillary all her lies!!!
Hillary is, as always Hillary plus nothing;!
America is great.

I was quite bored... Not too efficient, but fun!

Pseudocode:

var nothing = 1, Putin = 3, Trump = 5, America = Putin * Trump, Ivanka = 101, Hillary = nothing;
while Hillary < Ivanka
var China = Democrats = Obama = Hillary;
while China > America
China = China - America;
while Democrats > Trump
Democrats = Democrats - Trump;
while Obama > Putin
Obama = Obama - Putin;
if China == America
print "FizzBuzz";
else if Democrats == Trump
print "Buzz";
else if Obama == Putin
print "Fizz";
else
print Hillary;
Hillary = Hillary + nothing;
America is great.

33o<CR>Fizz<CR><Esc>qqABuzz<Esc>5kq19@q:%s/^$/\=line('.')<CR> On vimgolf.com we have the classic Remember FizzBuzz?, which is similar to this, but keeps the numbers on all the lines. There's also Neither Fizz nor Buzz, which uses a similar format, but provides a useful input file. Those small differences drastically change the optimal solution. I did exactly this same variation 2 years ago in the edit to this reddit post. I had to check whether visual increment (not available back then) creates an improvement, like it has for the other variations, but it looks like it hasn't. • 33o<CR>Fizz<CR><Esc>: Create the Fizz lines AND the blank lines with a simple insert mode repeat. Much quicker than a macro. AFAIK first discovered by @KersonHsiao in the vimgolf.com version, and used by every top solution since. • qqABuzz<Esc>5kq19@q: A very simple macro appends the Buzzes. • :%s/^$/\=line('.')<CR>: Replaces all blank lines with that line's line number. The expression replacement is very long, so this tactic is rarely used in vimgolf, but the alternatives are all worse.

Common Lisp, 123 116

(dotimes(i 100)(loop for(m s)in'((3"Fizz")(5"Buzz"))if(=(mod(1+ i)m)0)do(princ s))(do()((fresh-line))(princ(1+ i))))


Pretty-printed

(dotimes (i 100)
(loop for (m s) in '((3 "Fizz") (5 "Buzz"))
if (= (mod (1+ i) m) 0)
do (princ s))
(do () ((fresh-line)) (princ (1+ i))))


The do/fresh-line trick

The inner loop iterates over ((3 "Fizz") (5 "Buzz")) for each i and, according to the result of the two consecutive mod operations, eventually prints:

• nothing
• or Fizz
• or Buzz
• or FizzBuzz

fresh-line is a nice little function that as far as I know is only found in Common Lisp. It adds a newline only if necessary, and returns T only when the newline was added. For the above situations, according to whether we printed something or not, the return values of (fresh-line) are thus respectively:

• NIL
• T
• T
• T

So I know that the integer must be printed only when we did not print a fresh-line. But if I print the integer, I must also print a newline after it. That's why there is a DO.

DO is a basic yet almighty looping construct that iterates until a condition is met. Here, the condition is the return value of (fresh-line). It it tested before each iteration of the body of the loop, notably the first one. So if the test returns T, then we exit the DO. Otherwise, we execute the body, which prints the integer. Then, we execute the test once again and this time, it returns T because current line is "dirty" (there is an integer printed now).

BuzzFizz, 86 bytes

$a++ if3$$\a:print"Fizz" if5\$$a:print"Buzz" else:print$a
print"\n"

# If $a is *not* divisible by 100, we have another iteration. So loop # back to the start of the program. else: loop  Discussion In addition to the commands seen in the FizzBuzz program above, BuzzFizz also supports input (if you use an identifier like a with no leading $, the program will ask for its value; you can use a statement like clear a to reset the value so that the program asks for it again the next time it's used). Other than that, the above program shows off all the features of the language; in other words, we have a complete language built entirely out of the operations you need to write a simple FizzBuzz program (thus the name).

Despite its inspiration, BuzzFizz is not specialised merely for FizzBuzzes; you can take the FizzBuzz program apart, put it together in other ways, and solve a surprisingly large range of problems. For example, the Esolang page for the language has a primality tester and a program which adds two positive numbers. (The primality tester is simpler than the addition program; given BuzzFizz's choice of operator, this probably shouldn't be too surprising.)

That said, the language is (intentionally) not Turing-complete; the original inspiration of the language was to act as a counterexample to people who made claims of the form "any language that can do X must be Turing-complete", as the most common choices of X don't actually require it. On the other hand, it's also (intentionally) very powerful for a sub-Turing language; it's fairly hard to come up with simple problems that BuzzFizz can't solve and Turing-complete languages can.

Brainfuck, 16321 3602 1597

Almost as short as Java. This is just the trivial answer generated by another program, This is still a computer generated answer, but I am sure there are way shorter solutions! The general idea is initializing the cells to 4 B F i u z. If the program has to output a number, it just goes to the first cell and manipualtes it, if it is one of the letters, it will just jump to the corresponding cell and output it.

Rotor, 32 31 bytes

1N2{3%!"Fizz"~5%!"Buzz"N$?~N}\  This has one unprintable, so here's a hexdump: 0000000: 314e 7f32 7b33 2521 2246 697a 7a22 7e35 1N.2{3%!"Fizz"~5 0000010: 2521 2242 757a 7a22 4e24 3f7e 4e7d 5c %!"Buzz"N$?~N}\


Explanation:

1  Push a one to the stack.
N  Push a newline.
^? Spooky invisible unprintable that pushes 100 to the stack.
2  Pushes a two to the stack.
{  Starts block.
3%      Takes mod 3 of the top number on the stack.
!"Fizz" If falsy, push "Fizz".
~       Push the contents of the register.
5%      Takes mod 5.
!"Buzz" If falsy, push "Buzz".
N$Compares the top value of the stack to a newline. (this doesn't pop the values off the stack) ?~ If truthy, push the contents of the register. N Push a newline. }\ For loop between 2 and 100, pushing the counter to the register and stack each time.  Try it online. (note that it is very slow) Check out Rotor.

I'm only submitting this as a separate non-competing answer because it wouldn't be possible to explain fully in a comment. Changes: • Use SI to reset BX since DOS sets SI initially to 100H (ref) instead of an imm. (-1 byte) • Instead of using a 3/5 counter in DH/DL, use AAM for modulo operations on counter. AAM is a 2 byte instruction that's effectively a byte-length DIV that can accept an imm value as the divisor and also sets ZF if AL mod n = 0. @Peter Cordes touches on this in his very brilliant post about FizzBuzz in assembly. (-5 bytes) • Instead of CR/LF, use LF/CR (the order doesn't matter to DOS). This translates to an instruction that does not modify the startup value of AX (in fact it zeroes out AL) so we can eliminate the xor ax,ax and save two bytes. It does come at a cost because 0A 0D is only a two-byte instruction so the rest of the 24xx instruction needs to be padded with one more byte. (-1 byte) Unassembled: Per @Peter Cordes's request, instruction opcodes included in listing: 0A 0D or cl, [di] ; LF and CR bytes (newline) 24 00 and al, 0 ; DOS string delim ('$') + pad byte

• I recommend dropping the semi-colon at the end. Also I just used conditionals i%5?i%3?i:'Fizz':i%3?'Buzz':'FizzBuzz' and I got 79 bytes, so I recommend trying that. I would also avoid s="1" and just start i=1,s="" to save an extra byte – ShadowCat7 Sep 24 '15 at 20:44

Fortran, 213 bytes

character(len=8)::o

elseif(mod(i,3)==0)then;write(*,*)'Fizz'

endif;enddo;end


Not as graceful as the golf languages. I could save bytes using print instead of write, but print indents 1 space without a format specifier which would increase the byte count instead. Likewise I lose bytes printing the number because Fortran doesn't like left-justified output for numbers. I didn't bother sticking it all on one line as newlines and semicolons are both 1 byte -- no savings.
