Note to challenge writers as per meta consensus: This question was well-received when it was posted, but challenges like this, asking answerers to Do X without using Y are likely to be poorly received. Try using the sandbox to get feedback on if you want to post a similar challenge.


It's 2017 2018 2019 already, folks, go home.

So, now that it's 2014, it's time for a code question involving the number 2014.

Your task is to make a program that prints the number 2014, without using any of the characters 0123456789 in your code, and independently of any external variables such as the date or time or a random seed.

The shortest code (counting in bytes) to do so in any language in which numbers are valid tokens wins.

Rockstar, 34 32 bytes

X was up equalizing a word
Say X

Say hello to rockstar! (No I didn't make this one)

Explanation:

This first line:

X was up equalizing a word

Uses Rockstar's Poetic number literals. (As opposed to regular literals, which use numbers).

This means that the length of every word after was indicates the digit in that position. So here we have a 2 length (up), a 10 length (equalizing) a 1 length (a) and a 4 length (word). The length is % 10, so equalizing becomes a 0, and the result is that the variable X has the value 2014.

Then of course we print it with Shout

           [_::_]   # From the 4th character, take every 4th character
                    # Output the contents of _ implicitly

A more interesting solution at 34 bytes:

_=-~(_==_)
_=`_`+`_-_`+`_/_`+`_*_`

Try it online!

_=-~(_==_)               # Set _ to 2
_=`_`+`_-_`+`_/_`+`_*_`
# '2'+'2-2'+'2/2'+'2*2' = '2'+'0'+'1'+'4' = '2014'

Edited: bash 81 chars!

Just for fun:

wc -c < <(echo {,}{,,}{,}{,,,}{,}{,,,}film dbugjkqstvxz{,}{,,} 'Happy New Year!')

there is no numbers, all letters are used and this print exactly:

2014

( This method could reasonably be used until 2016: by just adding one or two exclamation point after the wish:

   wc -c < <(echo {,}{,,}{,}{,,,}{,}{,,,}film dbugjkqstvxz{,}{,,} 'Happy New Year!!')
   2015

;-)

bash 27 chars

.;v=$?;echo $v$?${#v}$[v+v]

This will output:

bash: .: filename argument required
.: usage: . filename [arguments]
2014

Ok, this will generate some unwanted output, but 2014 is printed and is a valid token!

The two following sample are error free (a little longer but near golfed)

v=$(echo {V..v});echo $[${#v}#vu]
2014

or

printf -vv "%d" $?xfbc;echo $[v>>${#?}]
2014

or even:

echo $[$[$[${#?}$?-${#?}]$?>>${#?}]#Iy]
2014

Inspired by comment from GammaFunction:

echo $[$[a-a]xfbd>>${#?}]

e-TeX, 21 bytes

\the\numexpr`*`j\bye

It contains an invisible control character with code 19 (0x13) before the asterisk. A version with printable ASCII characters needs two more bytes:

\the\numexpr`^^S*`j\bye

In TeX ` takes the character code of the next token:

  • [0x13] (^^S): 19
  • j: 106

\numexpr calculates: 19 * 106 = 2014

The result is a DVI file with "2014" on the first page.

Variant with 2014 as page number:

\pageno\numexpr`^^S*`j~\bye
