1, 2, Fizz, 4, Buzz!
The task
Output the first 100 elements of the infamous FizzBuzz sequence.
How?
The FizzBuzz sequence is the sequence of decimal integers from 1 to 100 inclusive, but:
 If the integer is divisible both by 3 and 5, output the string
FizzBuzz
 Else, if the integer is divisible by 3, output the string
Fizz
instead  Else, if the integer is divisible by 5, output the string
Buzz
instead  Else, output the integer itself
Output
The output will be a list of these elements separated by either a space (U+0020
) or a newline (U+000A
).
Here is a sample output with newline separation:

Rules
 Your code may not print anything to STDERR. Warnings are fine.
 This is codegolf, so lowest bytecount in each language is the winner.

i;main(){while(i++<100){char*h[]={"%d "," "},**p=h;i%3(*p++="Fizz%2$s");i%5(*p="Buzz ");printf(*h,i,h[1]);}}
This compiles with several warnings, but no errors.
Here's an ungolfed version with explanations:
/* the following include is omitted; while using printf
without including it is not conforming to the current
C standard, with gcc it only generates a warning
and works flawlessly. Note that omission was valid K&R C */
#include <stdio.h>
/* Declare a global int variable. The golfed code omits the
type because of the old implicitint rule, which only
generates a warning also in modern gcc. Also note that
global variables without initializer are zeroinitialized;
this is still defined behaviour today. In this ungolfed
code I've added the implied initializer for clarity. */
int i=0;
/* The main function. Again, the golfed code makes use of the
old implicit int rule. */
int main()
{
/* loop up to 100; since we increment before entering the
loop body, the first number in the loop is 1. */
while(i++<100)
{
/* In this array of two strings, the first will be used as
format string to a printf later, while the second will
be the third argument for the same printf. As is, the
format string will tell printf to format the second
argument (which will be i) as number, followed by a space.
The third argument, a singlespace string, is ignored
in that case. */
char *h[] = { "%d ", " " };
/* This second variable (which in the golfed version is
declared in the same declaration as h) points to the first
entry of h. It is used to change the entries of h, and
it is separate because pointer arithmetic is used to
modify different strings depending on the condition. */
char **p = h;
/* This is basically an ifnot statement. If i%3 is not
nonzero (that is, if i is divisible by 3), this statement
replaces the format string with one that prints "Fizz"
followed by the content of the third argument of printf
as string, which is the second string in h. At this
point it contains just a space. Also, when replacing the
format string, the pointer p is incremented, so it then
points to the second element of h. */
i%3  (*p++ = "Fizz%2$s");
/* This ifindisguise handles divisibility by 5. It stores
a pointer to "Buzz " into whatever p points to. If i
is not divisible by 3, this still is the format string,
so if instructs the following printf to just print "Buzz "
and ignore any further arguments. Otherwise, p points
to the final string argument, so that after the "Fizz"
it prints "Buzz " instead of just a space. */
i%5  (*p = "Buzz ");
/* This finally is the printf statement talked about
in the previous comments. Note that *h is equivalent
to h[0] */
printf(*h,i,h[1]);

Nice solution since it's quite straightforward, +1. I managed 108 bytes with same compiler settings (default gcc) but a much more obscure solution here.
goruby, 1 byte
f
Okay, so that's a bit unfair. 😂 The definition of f
from golf_prelude.rb
(which is what goruby embeds) is quite golfy in itself:
def f(m = 100)
1.upto(m){nputs'FizzBuzz
'[i=n**4%15,i+13]n}
end
Substituting m
with 100 directly gives us the Ruby version, which weighs in at 51 bytes:
1.upto(100){nputs'FizzBuzz
'[i=n**4%15,i+13]n}

My last attempt was nearing the 20000 byte zone, because it didn't use the stack at all.

Works by adding the FizzBuzz line breaks and words to the stack (in reverse) for the first 90, adds the last 10 lines, then goes through and prints all the numbers and words by recalling the stack at specific times. SPL doesn't support division so this is the shortest method I could think of, short of subtracting numbers and checking if they... equal... zero...
Oh god, I've gotta go golf more. I'm leaving this here as a mark that I've done something, though.

this language is fantastic
C (gcc), 108 bytes
*h,i;main(){for(;i++<100;){char s[]="%dFizzBuzz ",b=i%5;h=s+2;printf(s+(i%3?b?*h=32,0:6:b?h[1]=32,2:2),i);}}
Godbolt. Works on clang too. Contains some serious abuse of all that is holy: gcc extensions, misaligned writes, endianess, poorlydefined behavior...
Newline instead of space, 109 bytes:
*h,i;main(){for(;i++<100;){char s[]="%dFizzBuzz\n",b=i%5;h=s+2;printf(s+(i%3?b?*h=10,0:6:b?h[1]=10,2:2),i);}}
I'm a rookie at code golf so this could probably be improved a lot.
Explanation:
The whole code is based on a local string s
which is refreshed at each lap of the loop.
Basically the whole expression is a big ifelse written with ?:, designed to return a pointer offset to the string as result.
 In case a normal number should be printed, a space and null terminator is inserted after
%d
.  In case
FizzBuzz
should be printed, the array offset is increased with pointer arithmetic to start from Fizz.  In case only 'Fizz' should be printed, a space + null terminator is inserted after
Fizz
.  In case only 'Buzz' should be printed, the array offset is increased with pointer arithmetic.
Space + null terminator is written by a lvalue access of int
through h
to the string, which is both a strict aliasing violation, a misaligned access and endianess reliance all at once. The raw data of 0x00000020
is written into the string, little endian meaning that 0x20 ends up in ls byte and then a 0x00 byte after that, forming a null terminator.
printf
is abused by getting passed an additional parameter i
whether or not the format string contains any conversion specifier.
gcc extensions abused:
 implicit int

main()
form and noreturn 0
in case of C90.  no
#include
 incompatible pointer conversion from
char*
toint*

I'm pretty sure U+0020 is the space, and U+000A is the newline. BTW, what exactly does "must not produce an error from start to finish" mean? In particular, do compiler warnings count as errors in this context? — celtschk about 2 months ago
@celtschk fixed, thanks — Dion about 2 months ago
Now I'm sad. SPL relies on STDERR to be golfed effectively, heh.Time to double the length of my program... — Corsaka about 2 months ago
@corsaka if you think it is acceptable to change the rules at this point, then I can edit the post so that programs may not HALT on errors — Dion about 2 months ago
Wait, are warnings considered STDERR? If not, that solves the issue. If yes, then the top answer is also incorrect. — Corsaka about 2 months ago
