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

Buzz

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.

  • 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.

    \$\begingroup\$ Nothing can be printed to STDERR. Is this true only when running, or also when compiling (assuming that is a separate step?) \$\endgroup\$ – AShelly Sep 24 '15 at 20:47
  • \$\begingroup\$ @AShelly Only when running \$\endgroup\$ – Beta Decay Sep 24 '15 at 20:48
  • \$\begingroup\$ 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. \$\endgroup\$ – Timwi Sep 24 '15 at 23:28

    \$\begingroup\$ @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. \$\endgroup\$ – Geobits Sep 25 '15 at 0:50

    [\100*\/ Divide number * 100 by the divisor to get decimals
    $100$@/* Get truncated result
    -0= Subtract to get decimal, if equal to 0, then the modulo is zero and return true. If not, return false as we don't care about the result
1 Put counter on stack

[0\$3m;![\%1\"Fizz"]?$5m;![\%1\"Buzz"]?\0=[$.]?10,1+]# Do FizzBuzz if not
    [0\ Number to see if both % 3 and % 5 failed
    $3m;! Number % 3
    [\%1\"Fizz"]? If yes, do what is in brackets
        [\%1\ Set number to 1
        "Fizz"]? Print Fizz
    $5m;! Number % 5
    [\%1\"Buzz"]? If yes, do what is in brackets
        [\%1\ Set number to 1
        "Buzz"]? Print Buzz
    \0= Check if both modulo functions failed
    [$.]? If yes, do what is in brackets
        [$ Duplicate our counter so it doesn't get destroyed
        .]? Print the counter

Could most likely be way better.

This isn't a good, or small solution, but it works:

for(let i=1;i<101;i++){console.log((i%3==0&&i%5==0)?"FizzBuzz":(i%3==0)?"Fizz":(i%5==0)?"Buzz":i);}

Explanation:

for (let i=1;i<101;i++) // Loop through, until reaching 100
{
    console.log(
    (i%3==0 // If I is a multiple of 3
    &&      // And
    i%5==0  // If I is a multiple of 5
    )?"FizzBuzz": // Print "FizzBuzzz"
    (i%3==0)?"Fizz":  // If I isn't either of those, check whether I is a multiple of 3, if so, print "Fizz"
    (i%5==0)?"Buzz" // If I isn't a multiple of 3, check whether I is a multiple of 5, if so, print "Buzz"
    :i // Else, just print i
    );

        // there is a 6th bit in bit 9, but that is only for larger offsets.
        //
        // .Lnoprint is exactly 4 bytes after the instruction, so the offset

        //   0 0 0 0 0 r r r

My second submission in my brand new WIP ThumbGolf language, an ISA extension to Thumb-2.

It shows off both the new I/O instructions and the modulo instructions (with the special narrow encoding for 10).

That little hack by null terminating with cbz saves a lot, and it was really fun to figure out.

As mentioned in my cat program, this can be run on ARM Linux or QEMU by linking the ThumbGolf runtime. I don't have an online interpreter yet (and I doubt I could afford hosting one lul)

Not the best solution we have, but not the worst either... The "nested" ternary operator adds either buzz or nothing to the fizz part depending on the results of the divisibility test.

    # this is how while empty?; do something; done works:

    # NOTE: Fail on pxemi dot 7z and RPxem

  .a\n.oXX.z # print "\n"
  .a.m\001.+XX.z # push heap; add one to it
.a.ct.aXX.z # break if equal to 116
.a

Note

  • In Pxem, unlike other stack-based languages, subtraction and division does NOT rely on positions of two items; .- does push(abs(pop-pop)), .$ and .% stand for x=pop; y=pop; push(int(x>y?x/y:y/x)) and x=pop; y=pop; push(int(x>y?x%y:y%x)) respectively. Thus, when you try to do something like 13/17 or 13%17, you need to check which are greater first.
  • To avoid the specification, the program loops from 16 to 115.

Not as clever as feersum's solution, but it avoids casting exec magic.

EDIT: with just two more parentheses, it works in Python 3 AND Python 2:

JavaScript (using external library) (90 bytes)

x=>_.Range(1,100).Select(x=>x%3==0?(x%5==0?"FizzBuzz":"Fizz"):x%5==0?"Buzz":x).WriteLine()

Link to library: https://github.com/mvegh1/Enumerable/

Code explanation: Creates a range starting at 1 and extending 100 elements. Select maps the item according to the predicate. First check if divisible by 3, if so check if divisible by 5. If so, select "FizzBuzz", else select "Fizz". Otherwise,check if divisible by 5. If so, select "Buzz", else just select the number. WriteLine is built into the library, and it writes each element on its own line

DUP, 76 bytes

[$$3/%$[]['F,'i,'z,'z,]?\5/%$[]['B,'u,'z,'z,]?*[$.][]?10,]c:0[$100<][1+c;!]#

Explanation of program flow, code blocks:

DUP has two default truth values: -1 (true, all bits set) and 0 (false, no bits set). For conditional evaluations every nonzero value is accepted as true, comparisons themselves lead to either -1 or 0.

DUP has two conditional expressions, if-then-else and a while loop:

[execute if not false][execute if false]?. E.g. 1['t,]['f,]? prints t to STDOUT, because 1 is not false.

[condition][execute while not false]#. E.g. 5[$0>][$.1-]# prints the numbers 5,4,3,2,1 to STDOUT. The condition block tests the top stack value if it’s greater than 0, the execute block prints the number and decrements it.

The condition that’s checked is always the topmost stack element, which gets popped off the stack during the check.
