Output with the same length as the code

Question

In this challenge, you should write a program or function which takes no input and prints or returns a string with the same number of bytes as the program itself. There are a few rules:

• You may only output bytes in the printable ASCII range (0x20 to 0x7E, inclusive), or newlines (0x0A or 0x0D).
• Your code must not be a quine, so the code and the output must differ in at least one byte.
• Your code must be at least one byte long.
• If your output contains trailing newlines, those are part of the byte count.
• If your code requires non-standard command-line flags, count them as usual (i.e. by adding the difference to a standard invocation of your language's implementation to the byte count), and the output's length must match your solution's score. E.g. if your program is ab and requires the non-standard flag -n (we'll assume it can't be combined with standard flags, so it's 3 bytes), you should output 5 bytes in total.
• The output doesn't always have to be the same, as long as you can show that every possible output satisfies the above requirements.
• Usual quine rules don't apply. You may read the source code or its size, but I doubt this will be shorter than hardcoding it in most languages.

You may write a program or a function and use any of the standard methods of providing output. Note that if you print the result, you may choose to print it either to the standard output or the standard error stream, but only one of them counts.

You may use any programming language, but note that these loopholes are forbidden by default.

This is code-golf, so the shortest valid answer – measured in bytes – wins.

• Martin Ender: Related. Related.
• Martin Ender: @Mr.Xcoder Yes, if you declare them as such.
• Martin Ender: @DJMcMayhem I figured that in many esolangs it's trivial to print a null byte with one byte of code or similar things, and thought it would lead to more interesting answers if the results were actually readable.
• Wheat Wizard: @MartinEnder You should probably disallow output by exit code, which is a default. If you allow it nearly every one byte program in nearly every language is allowed. One user has already done this
• Martin Ender: @WheatWizard output by exit code is not a string, so it doesn't apply here.

Answer 1

brainfuck, 33 bytes

>+[-->---[-<]>]>+[->+>+<<]>[->.<]

Try it online!

Output:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I could do it in 32 bytes but I decided this is better.

• CalculatorFeline: Then do it in 32 bytes.
• Erik the Outgolfer: You should do it in 32 bytes or else it isn't a serious competing entry.

Answer 2

Braingolf, 1 byte

l

Try it online!

Prints 0 (the current length of the stack)

Braingolf, 2 byte

4*

Prints 16. 4 can be replaced by any number n where 3 < n < 10

Explanation:

4*
4 Pushes 4 to the stack
 * Monadic multiplication, squares the last item on the stack
 Implicit output of the last item on the stack

• Mayube: @LuisMendo That's the correct link. TIO doesn't have Braingolf yet, but the interpreter is written in Python3, which TIO does have. The code is the 2nd argument.
• Luis Mendo: Don't you think you should explain that in your answer then?
• totallyhuman: Doesn't the first solution print a trailing newline?

Answer 5

Perl 6, 4 bytes

{?1}

Try it

Returns True

Explanation

&prefix:« ? » is a Bool conversion operator

{ and } can be used to create a bare block lambda.

• Mark Reed: That returns the boolean value True, not the string "True". If you run it at the REPL it does display as "True", but does the trailing newline count when added by the REPL? I think you can fix both of those by doing {~?1}, which both adds a byte to account for the newline and explicitly stringifies the result.

Answer 11

Excel, 13 (12/11) bytes

=TEXT(9^13,0)

Genetrate a number, convert to text, simple!

(削除) Alternatively: (削除ここまで) =1=1 evaluates to TRUE (4bytes)

TRUE is boolean not text

Update

Very debateably for 12 and 11 bytes respectively

=TEXT(9^12,0

Leaving off the close bracket evaluates without a fuss

=REPT("a,11

Leaving out a bracket and " still evaluates although you get a "did you mean...?" prompt correcting the formula. I think the 1st is probably fine, the 2nd probably isn't.

Answer 12

VBA Immediate Window, (削除) 9 (削除ここまで), 2 bytes

?,

Prints a tab followed by a newline according to this answer in meta

Old answer

?space(6)

Entered in the immediate window, space(n) repeats the space character n times, ? is short for Print & Debug. is implicitly prepended in the immediate window. Printing also gives a space after the function and 2 newlines so only 6 spaces needed

• MD XF: Nice job! Golfing down to 22% of original code in one step is pretty impressive.

Answer 13

R, 8 (削除) 9 (削除ここまで) bytes

Answer 17

Frink, (削除) 9, (削除ここまで) (削除) 11, (削除ここまで) 10 bytes

print[13!]

Outputs:

6227020800

Such a ... boring solution, sigh.
*no trailing newlines.
*Although Frink parses unicode exponents {+- 0-9}, print[99] is 11 bytes, not 9.
Frink has a large data file of constants, but I haven't yet found a < 4 char one that outputs < 11 bytes. (constants have units, and frink is very verbose by default)

• Ørjan Johansen: That 9 seems to be 3 bytes.
• maybeso: grr, of course it is. So silly of me to trust the byte size of the native-editors saved file without reloading it to check for corruption. (I did check if it appended a newline)

Answer 18

Batch - 6 Bytes

xcopy^

Not sure if this counts, but the typing this in cmd will give the output:

More? 

(With a trailing space)

• stevefestl: typing this command in a batch file can cause security issue - See here: stackoverflow.com/questions/15466298/…

Answer 19

Bash + coreutils, 5 bytes

id -u

Technically depends on the user ID, but the default user has id 1000 on all major distros, and unless you set up 9,000+ additional users, all others will also have a four-digit id.

Finally, this works on TIO, so I'd argue it meets our must work in one implementation rule.

Answer 21

Klein, 3 + 3 = 6 bytes (non-competing)

Non-competing because " was added after this challenge. +3 bytes for the 000 topology flag.

"@.

Try it online!

Prints 64 46 and a trailing linefeed.

Explanation

With the 000 topology the source code just wraps around like in many other fungeoids.

"@." Push the code points of '@', 64, and '.', 46, to the stack.
@ Terminate the program.

At the end of the program, the stack contents are printed as decimal integers with space-separation and a trailing linefeed.

I also tried for 5 with "@ and a suitable topology that lets the IP traverse more cells before hitting the " again, but the implicit cells (used to pad the code to a square) are ., so we can only ever print 2-digit numbers, and therefore we can't possibly get to 5 bytes of output with this technique.

Answer 22

BotEngine, 5 bytes

TIRES

(Or any other program of the same length which starts with a T)

Prints TRUE, followed by a trailing newline (which apparently counts for this question).

Answer 23

Perl 5, 7 bytes

say$"x6

$" contains a space by default, and x6 duplicates it six times. say prints and adds a newline, so this prints six spaces followed by a newline.

• Ørjan Johansen: It seems that say requires a use declaration to enable it.
• Chris: @ØrjanJohansen Normal execution of a perl one-liner is with the -E flag, which automatically enables all optional features, including say. That is, execute it like perl -E 'say$"x6'
• Dada: Saying that "normal execution of a perl one-liner is with -E flag" isn't quite right. However, here on PPCG, we allow Perl one-lines to be ran with -E flag instead of the usual -e
• Chris: @Dada Well, it's up to taste I suppose. There's rarely any reason not to use -E, so I'm in the habit of doing so.

Answer 24

MainRamCounter, 6 bytes

"a"e6R

This is a new language I am currently developing. It is based off of 3 storage spaces: Main (which does comparisons and math), Ram (which stores values), and counter (which is a counter).

Breakdown:

"a" push 97 to ram
e6 duplicate current ram 6 times
R output ram as string

Output:

aaaaaa

Answer 27

C#, 53 bytes

Not short, but good enough:

string a="1";for(int i=0;i<53;i++){Console.Write(a);}

Some Facts I can't resist to post:

• Fifty-three is the 16th prime number. It is also an Eisenstein prime, and a Sophie Germain prime.

• 53 cannot be expressed as the sum of any integer and its base-10 digits, making 53 a self number.

• 53 is the smallest prime number that does not divide the order of any sporadic group.

Answer 28

C#, 12 bytes

()=>1e11+"";

It returns 10^11, which is a 1 followed by 11 0-s, so 12 bytes long.

Answer 29

cQuents, 5 bytes

#3::$

Outputs 1,2,3. This works because of the mode, ::. :: prints the sequence up to n, which in this case is hardcoded in as 3. $ prints the current index - it could be replaced with any single digit. So, the interpreter prints out the first three items in the $ sequence, separated by the default delimiter, ,.

Answer 30

Common Lisp, 5 bytes

1e+01

in the Common Lisp REPL it produces 10.0 plus linefeed, for a total of 5 bytes.

Thanks to @MartinEnder for noting an error in the previous 4 bytes version!
