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

Javascript, 10 bytes

alert(1e9)

Nodejs repl (maybe breaking rule)

Answer 2

Aceto, (削除) 9 (削除ここまで) 1 byte

p

Prints the top value on the stack, an implicit 0.

---

Old solution (9 bytes):

p×ばつ
19

Push a 1, push a 9. Multiply the (remaining) stack (by 9; → [1,1,1,1,1,1,1,1,1]).

Implode and print (prints 111111111).

The code is 9 bytes long in UTF-8 because \ and ×ばつ take 2 bytes each.

• caird coinheringaahing: This outputs a number but the challenge says it must be a string
• theblitz: "You may only output bytes in the printable ASCII range (0x20 to 0x7E, inclusive)" Digits fall in that range

• Martin Ender: What language is this?
• Animesh Das: Edited. Python 2. Made it in 88 bytes. First timer in code-golf.
• Martin Ender: Welcome to PPCG then! What are the imports for?
• Animesh Das: Initially I thought I could use the randrange() function from the file "random". "import math" is for validating the 1E19 I placed later on.
• Animesh Das: I can see there are better ways to get through, though. For example, I could do away with "import random", since I'm not using randrange() here.

Bean, 2 bytes

00000000: 253b %;

Explanation

Implicitly prints a 2 followed by a newline. I arbitrarily decided it should output the amount of bytes the program is, but this will work with many single characters in the printable range.

Answer 8

JavaScript, 32 bytes

Code: btoa(01234567891011121314151617)

Output: MS4yMzQ1Njc4OTEwMTExMjEzZSsyNA==

console.log(btoa(01234567891011121314151617))
console.log(btoa(01234567891011121314151617).length)
console.log("btoa(01234567891011121314151617)".length)

• ASCII-only: Invalid, without explicit output you need to say that it's in a repl
• Jamie Barker: Not sure why you're bothering with a thread/post that's 2 years old, but the console.log is for the purpose of the code snippet preview only. Put those commands directly into the browser console and you'll see the correct result.
• ASCII-only: Well, yeah if you're using console.log it would be "Javascript (<browser name>)". As for the reason why I'm bothering, just because it's two years old doesn't mean it's allowed to be incorrect :P (plus, this question was active recently so I clicked on it and saw this)
• Jamie Barker: Well, it's JavaScript, it's never going to win any Code Golf xD
• ASCII-only: Well, remember here you compete within the same language (well, kinda). The goal here is more to basically catalogue shortest solutions, I guess?

print IVXLCDM

The constant rn represents the string containing the Roman numerals.

The h operator terminates the program and prints all existing objects. The a operator is only to reach 7 bytes (there is no constant that has 6 characters).

+1

This outputs 1, then a newline.

• Dennis: TIO doesn't execute the code in a REPL. You need echo or similar in a full program.

Outputs a newline and nothing else.

This works not just with an underscore, but any character from: Qq'_"# (because these are all printing based commands, but there is nothing to print).

Answer 22

POSIX bc, 1 Byte

a

output:

0

Explanation: If you type a variable name it prints the value. Variables you haven't yet defined have the value zero.

• Kai Burghardt: The program needs to be two Bytes: a) printf 'a' | bc produces a syntax error. b) printf 'a\n' | bc | wc ‐c reports two bytes. The output string 0 is actually followed by one newline character and thus must be counted too.

• Jonathan Frech: Hello and welcome to PPCG. I am unfamiliar with Red / Rebol though this seems to only work in the REPL. If this is the case, please change the language name to something along the lines of Rebol REPL. To conform to our lax guidelines, you could also make your language name a header.
