Your task is simple. Post a snippet in any language that if the snippet is repeated n times, will output n in decimal, octal, and hexadecimal, in that order, separated in spaces. n is an integer larger than zero. There is no leading zeroes. Shortest answer wins

## Example

If the snippet is ABC then the test case is

ABC
1 1 1
ABCABC
2 2 2
ABCABCABCABCABCABCABCABCABC
9 11 9
ABCABCABCABCABCABCABCABCABCABCABCABC
12 14 C
ABCABCABCABCABCABCABCABCABCABCABCABCABCABCABCABCABCABC

• If you have a language with implicit input/output, then you could have a 1 byte solution that just incremented the value... Dec 1 '16 at 5:00

printf"\r%d %o %x",++$n,$n,$n;  Go back to the beginning of the line, increment counter and print counter overwriting the old output. • +1 for spotting a hole in specification, Output erasure make this challenge trivial. Jan 2 '16 at 5:07 • @ChristianIrwan: actually it's not erasing, but overwriting (I've corrected my description) – nimi Jan 2 '16 at 7:29 • That both ruins the challenge.

I'm actually kinda surprised this works.

### Explanation

var d=-~d;  // var let's d not throw an error if it's not defined
// -~ essentially increments the variable
d+                    // decimal
 ${ // space character d[b='toString'](8) // octal }  // space character +d[b](16) // Hexadecimal  Try it online • Iirc you can remove the var Jan 2 '16 at 5:47 • @CᴏɴᴏʀO'Bʀɪᴇɴ that causes an error: ReferenceError: Can't find variable: d, even on loose mode D: Jan 2 '16 at 5:50 • Does d=d?d+1:1 work? Jan 2 '16 at 5:52 • @CᴏɴᴏʀO'Bʀɪᴇɴ nope, still throws a reference error, weird considering loose mode is enabled... Jan 2 '16 at 5:53 • Ohhhh because we're trying to access d though it is undefined Jan 2 '16 at 5:54 # Japt, 12 bytes [°TTs8 TsG]¸  Thanks to @ETHproductions for saving 2 bytes!

Jan 3 '16 at 4:16 # C++, 205 179 bytes int main(){};static int c=1; #define v(x) A##x #define u(x) v(x) #define z u(__LINE__) #include <cstdio> class z{public:z(){++c;};~z(){if(c){printf("%d %o %x",--c,c,c);c=0;}}}z;//  (No trailing newline - when copied, the first line of the copy and last line of the original should coincide) Basically, this works by making a sequence of static variables which, on construction, increment a global variable counter. Then, on destruction, if the counter is not 0, it does all its output and sets the counter to zero. In order to define a sequence of variables with no name conflicts, we use the macro explained as follows: #define v(x) A##x //This concatenates the string "A" with the input x. #define u(x) v(x) //This slows down the preprocessor so it expands __LINE__ rather than yielding A__LINE__ as v(__LINE__) would do. #define z u(__LINE__)//Gives a name which is unique to each line.  which somewhat relies on the quirks of the string processor. We use z many times to define classes/variables that will not conflict with each other when copied onto separate lines. Moreover, the definitions which must occur only once are placed on the first line, which is commented out in copies of the code. The #define and #include statements don't care that they get repeated, so need no special handling. This code also features undefined behavior in the statement: printf("%d %o %x",--c,c,c)  since there are no sequence points, but c is modified and accessed. LLVM 6.0 gives a warning, but compiles it as desired - that --c evaluates before c. One could, at the expense of two bytes, add the statement --c; before the outputs and change --c in printf to c, which would get rid of the warning. Replaced std::cout with printf saving 26 bytes thanks to a suggestion of my brother. # CJam, 2019 18 bytes ];U):USU8bSU"%X"e%  Thanks to @MartinBüttner for golfing off 1 byte!

## OCaml, 198 bytes

;;open Char
;;(if Sys.argv.(0).[0]='~'then Sys.argv.(0).[0]<-'\000'else Sys.argv.(0).[0]<-chr(1+int_of_char Sys.argv.(0).[0]));let n=1+int_of_char Sys.argv.(0).[0]in Printf.printf"\r%d %o %x"n n n


Includes a trailing newline and requires that the filename starts with a tilde (I used ~.ml; you can run it with ocaml \~.ml) because it's the highest-valued standard printable ASCII character. Abuses the fact that all characters in a string are mutable and Sys.argv.(0).[0] is the first character in the filename.

It should only work for n = 1 to 126, because the ASCII code for ~ is 126 and I'm adding one to the output. It could be made two bytes shorter if we only want n = 1 to 125. After it's repeated 126 times, it'll cycle back to n = 1.

This is my first ever golf so any comments or improvements would be much appreciated.

Ungolfed version:

;; open Char
;; if Sys.argv.(0).[0] = '~'
then Sys.argv.(0).[0] <- '\000'
else Sys.argv.(0).[0] <- chr (1 + int_of_char Sys.argv.(0).[0])
;; let n = 1 + int_of_char Sys.argv.(0).[0] in
Printf.printf "\r%d %o %x" n n n

$_=<<'';printf"%d %o %x",(1+y/z//)x3; :  There's a final newline behind the colon. Treats everything after the first line as a here document and counts the z in it. For every further copy of the code one z is added. We have to add 1 to the count, because there's none for the first snippet (the one that is executed). If additional output to stderr is allowed, we can omit the 2 single quotes '' and can get down to 38 bytes. Without the '' perl emits a warning about a deprecated feature. # Mathematica, 76 bytes Note that n should have no definitions before. 0;If[ValueQ@n,++n,n=1];StringJoin@Riffle[IntegerString[n,#]&/@{10,8,16}," "]  Here, the behaviour of ; is used. The snippet above is one single CompoundExpression, however, when a couple of snippets are put together, there is still one CompoundExpression as is shown below. (Some unnecessary rearrangements are made.) 0; If[ValueQ@n,++n,n=1]; StringJoin@Riffle[IntegerString[n,#]&/@{10,8,16}," "] 0; If[ValueQ@n,++n,n=1]; StringJoin@Riffle[IntegerString[n,#]&/@{10,8,16}," "] 0; If[ValueQ@n,++n,n=1]; StringJoin@Riffle[IntegerString[n,#]&/@{10,8,16}," "] (* 3 3 3 *)  So one cannot make such snippet works if writting explicit CompoundExpression. Also, almost everything you like can be put before the first ; such as E, Pi or MandelbrotSetPlot[],. ## bash, 49 bytes File count.bash: ((++n));trap 'printf "%d %o %x\n"$n $n$n' exit;

# Python 2, 54 bytes

n=len(open(__file__).read())/54;print n,oct(n),hex(n)#


No trailing newline. Outputs in the form 1 01 0x1.

If that's not ok, 56 bytes

n=len(open(__file__).read())/56;print"%d %o %x"%(n,n,n)#


When pasted in front of each other, the length of the file gets longer by 1 line for each time pasted. The base case starts with 2 lines so you have to subtract 1 from the line length. Computation is suppressed by the comment.

• "%d %o %x"%(n,n,n), that is pretty cool. I had no idea you could do that. If it turns out that leaving prefixes is not ok I'm going to have to borrow that. Jan 3 '16 at 7:20

This was not meant to be an overly competitive solution, but a method that I found amusing, being for one thing, an attempt at a multithreaded code golf.

import thread;n=eval("n+1")if"n"in globals()else 1;
def t(c):99**99;print("%s "*3)%(n,oct(n),hex(n))*(c==n)


Keeps a counter, spawns a thread for each count and if the counter has not changed when the counters timer goes off after a completing an expensive math problem (instead of a timer to save bytes), the formatted string is printed.

Some example configurations and their outputs:

import thread;n=eval("n+1")if"n"in globals()else 1;
def t(c):99**99;print("%s "*3)%(n,oct(n),hex(n))*(c==n)

Outputs 1 01 0x1


and fifteen copy pastes:

import thread;n=eval("n+1")if"n"in globals()else 1;
def t(c):99**99;print("%s "*3)%(n,oct(n),hex(n))*(c==n)
def t(c):99**99;print("%s "*3)%(n,oct(n),hex(n))*(c==n)
