Output with the same length as the code

Question 10

Nice. I was about to propose p p, but didn't think about the newline.

Question 11

APL, 2 bytes

-1

Prints ̄1 _{(the - is the Minus monad, whereas ̄ is the High minus negative indicator)}.

Question 12

C#, (削除) 22 (削除ここまで) 16 bytes

()=>$"{1L<<50}";

-6 bytes thanks to Orjan Johansen, using long instead of int.

Outputs

1125899906842624

Alternately, if you allow an arbitrary parameter to be passed into the lambda:

C#, (削除) 21 (削除ここまで) 15 bytes

_=>$"{1L<<49}";

Outputs

562949953421312

Question 13

If you use long you can do it shorter with only one group: ()=>$"{1L<<50}";. Try it online!

Question 14

Good job on posting such a short C# answer. You can also shave of a byte by using +"" instead of string interpolation.

Question 15

Neither 1L<<50+"" or ""+1L<<50 works for me due to << having lower precedence than +, so would need to add parens making the length the same.

Question 16

Why do you include a semicolon? It's not part of the function.

Question 17

Cubix, (削除) 6 (削除ここまで) 4 bytes

@"Ou

Cubified

 @
" O u .
 .

This pushes the string Ou. to the stack, Outputs the top character (.) as a character code (46), does a u-turn to the right, Outputs again, and exits with @.

Question 18

very nice answer, @(Ou works as well

Question 19

Excel, 7 bytes

=9^7&""

Produces a 7 digit number and then appends empty string

Uses general idea from pajonk in their answer [although obviously not the language trick :)]

Question 20

Welcome to PPCG! I edited your header so that it gets picked up by the leaderboard. :)

Question 21

"Why not just make a 4 digit number?" The challenge states that the function must return a string. It can be checked by T function whether something is string in Excel - the first solution isn't, the second is. Anyway, upvote as promised.

Question 22

@pajonk Great point. I have taken the smaller solution out as I agree it does not meet the conditions. Thanks!

Question 23

NodeJS REPL, 4 bytes

Did someone say REPLs are languages?

*;;;

→ ..._

(the underscore is actually a space character).

For anyone not familiar with the Node REPL, it thinks my program isn't complete, so it's prompting for the rest of the line.

Question 24

You could also use !!!0, 1e2 or ""

Question 25

JavaScript (ES6), 9 bytes

_=>""+1E8

Returns 1 * 10^8, or 100000000.

If I can return a number instead of a string, _=>1E5 is 6 bytes.

f=
_=>""+1E8
console.log(f())

Question 26

Beat me by a couple of minutes.

Question 27

Some of the Python answers seem to be outputting numbers, so you should be fine doing the same.

Question 28

@numbermaniac But they print them, which converts them to string.

Question 29

@numbermaniac OP (Martin Ender) told me it was wrong.

Question 30

a=b=>b+"" 9 bytes Include the function name :)

Question 31

QBasic 4.5, 1 byte

This prints nothing. Followed by a newline.

Question 32

Question 33

bash, 48 bytes

bash bash bash bash bash bash! bash! bash! bash!

Output:

/bin/bash: /bin/bash: cannot execute binary file

Question 34

−1: I downvoted this answer because there are substantially shorter options, for starters e. g. 17 Bytes echo $((10**15)).

Question 35

1/0

Inf
NaN
729

Question 36

Question 37

JavaScript (ES6), (削除) 17 (削除ここまで) 11 bytes

f=_=>"g="+f

Try it

f=_=>"g="+f
console.log("Function source: f="+f)
console.log("Function length: "+(""+f).length+" + 2 (for variable assignment) = "+((""+f).length+2))
console.log("Function output: "+f())
console.log("Output length: "+f().length)
console.log("Output type: "+typeof f())

Question 38

><>, 4 bytes

"on;

Outputs ;110

Question 39

Python 2, 10 bytes

print 9**9

Outputs 10 bytes:

387420489
*newline*

There are other 10-byte answers with decimals and power. I like this one for e in the output:

print.3**8

Output:

6.561e-05
*newline*

Same 10 bytes, but for division (there are 5 versions):

.1/64 = 0.0015625
.3/64 = 0.0046875
.5/64 = 0.0078125
.7/64 = 0.0109375
.9/64 = 0.0140625
print.1/64

outputs:

0.0015625
*newline*

Question 40

Also works in Cheddar

Question 41

@LeakyNun Why don't you post it as answer?

Question 42

Python 3, 53 bytes

s='s=%r;print("0"*~-len(s%%s))';print("0"*~-len(s%s))

This must be the most quine-like answer ever.

Question 43

Why not print(1e6)?

Question 44

@CalculatorFeline that would be un-quine-like.

Question 45

Your answer should not be a quine.

Question 46

@Notts90 this isn't a quine.

Question 47

dc, 2 bytes

Kp

Pushes the current precision on the stack (which is 0) and prints it with a trailing newline.

Question 48

dc prints a trailing newline after any command. The command 'c' has no other output, so it works and is one byte shorter

Question 49

Fourier, 1 byte

Try it FourIDE!

_{Note, TIO.run outputs a trailing newline}

Outputs the value of the accumulator, 0.

More interesting programs:

2P15o

Outputs 2¹⁵, 32768.

4^do

Outputs the current year (doesn't work if used before 1000 AD).

999**999o

Outputs 997002999. The ** is undefined behaviour in Fourier. The way I think it works is A**B = A*A*B.

Question 50

Alice, 5 bytes

g/@O

Prints:

103
g

Explanation

This was quite fun to figure out. :)

g Pop two implicit zeros from the stack and retrieve the code point at that
 location in the code. That's the 'g' itself, so we're pushing 103.
/ Reflect to SE. Switch to Ordinal. The IP bounces diagonally up and down
 through the code.
O Implicitly convert the 103 to "103" and print it with a trailing linefeed.
 Bounce off the top right corner and move back.
/ Reflect to W/ Switch to Cardinal.
g Push 103 again.
 The IP wraps back to the last column
O Interpret the 103 as a code point and print the corresponding character.
 This prints 'g'. 
@ Terminate the program.

Question 51

AWK, 21 bytes

BEGIN{printf"%21s",0}

Simply prints:

The 0 could of course be any digit. No new line is printed, since that would add 2 bytes.

Question 52

Underload, 6 bytes

()aaaS

Prints ((())).

() pushes an empty string to the stack. a "stringifies" it by wrapping it in (...) so after aaa we get (((()))). S prints that string (without the outermost parentheses, so we get only three pairs).

Question 53

Perl 5, 9 bytes

print$"x9

Prints 9 spaces, no newline.

Explanation

$" contains a " " by default. x9 uses the repetition operator to "multiply" the string by 9.

Question 54

Welcome to PPCG!

Question 55

Powershell, 38 bytes

Just for fun, an answer that returns different output each time it's called.

[System.Guid]::NewGuid().ToString("B")

Prints a GUID surrounded with braces ("B"), such as:

{24cc14a3-ada4-4fcd-8a08-ec419b00f22d}

Question 56

C (modern Linux), 19 bytes

main(){raise(11);}

Output (with newline):

Segmentation fault

How it works:

SIGSEGV is defined as 11 in /usr/include/asm-generic/signal.h. Therefore, raise(11) raises SIGSEGV, and when SIGSEGV is raised on Linux, all execution stops and Segmentation fault is printed.

20 bytes

main(){raise(2*2);}

Output (with newline):

Illegal instruction

22 bytes

main(){raise(2*3-1);}

Output (with newline):

Trace/breakpoint trap

22 bytes

main(){raise(5*2+5);}

Output (with newline):

User defined signal 1

22 bytes

main(){raise(1?26:0);}

Output (with newline):

Virtual timer expired

24 bytes

main(){raise(12*(1+1));}

Output (with newline):

CPU time limit exceeded

25 bytes

main(){raise(5*5?5*5:0);}

Output (with newline):

File size limit exceeded

25 bytes

main(){printf(raise(8));}

Output (with newline):

Floating point exception

Question 57

isn't that first one 18 bytes?

Question 58

@DestructibleLemon Nope. There's a newline at the end.

Question 59

why isn't the second one 20 bytes then?

Question 60

To be pedantic, all of these messages are written by the shell that launched your program, not by your program itself.

Question 61

@MDXF It really is the shell, not the kernel. You can prove it by running echo 'main(){raise(11);}' | gcc -xc -; echo ./a.out | strace bash, which shows bash making the write call. The exact format varies from shell to shell. Here is where the message is defined within the bash source code. You will not find it anywhere in the Linux kernel outside of documentation.

Question 62

Pyramid Scheme, 32 bytes

^ ^ 
-^-
^-^
-^-
^-^
-^-
^-^
- -

Explanation

This may not look like pyramid scheme but it is. Each triangle looks like:

 ^
 -

This performs one of three operations

If it has 2 args it pairs them together
If it has 1 arg it returns it
If it has 0 args it returns 0

So at the bottom we have two zeros, those are linked on the next level. On the next level two different pyramids grab the pair and then those pairs are paired together. This continues all the way up the pyramid. When we get to the top we have:

 ((((0,0),(0,0)),((0,0),(0,0))),(((0,0),(0,0)),((0,0),(0,0))))

Pyramid scheme's implicit output converts this to 16 zeros separated by newlines. That's 32 bytes.

Question 63

Java, 82 bytes

interface M{static void main(String[]a){for(int i=0;i++<82;)System.out.print(1);}}

Output:

1111111111111111111111111111111111111111111111111111111111111111111111111111111111

_{Crossed out 4 is still 4 ;(}

Question 64

Why not a lambda? I admit that it is boring, but I think it could be included to showcase Java 8.

Jelly, 1 byte

Quite a few Jelly one byters - this is one - it evaluates the left argument which, when nothing is provided as input, defaults to zero which in turn evaluates to zero and the result is implicitly printed, a 0.

Try it online!

In fact, of the 256 bytes in the code-page there are only 95 that do not currently produce a different one byte output within the specified range when run as a full program; these are (as code-page characters in byte order):

¡¢£¦©1⁄2¿€ÇÑÞßçıȷñ÷þ"#&',-./0123456789:;?@IMRTVZ\`dmpstxyz{}~°3459ƓƈɠḶỌṬḊĖİL·ṄȮṖṘẆẊṃọṣṭḃḟḣl·ṁṗṡẋż’"

Notes:

Most of the 1-byte programs print a 0 (no-ops / yielding a list with a single zero in, which prints a 0), most others print a 1 (0=0 and the like)
Ọ is the one program which does yield a different byte, but one which is out of range as per the specification - it produces the null-byte (casts the 0 to character)
6 produces a space (a literal)
7 produces a line feed (a literal)
Some bytes that do work now may not do so in the future - there are a fair few bytes being reserved (I believe) for niladic values which, when assigned, are almost certainly not going to produce one-byte output.

Fourier, 1 byte

Try it FourIDE!

_{Note, TIO.run outputs a trailing newline}

Outputs the value of the accumulator, 0.

More interesting programs:

2P15o

Outputs 2¹⁵, 32768.

4^do

Outputs the current year (doesn't work if used before 1000 AD).

999**999o

Outputs 997002999. The ** is undefined behaviour in Fourier. The way I think it works is A**B = A*A*B.

Alice, 5 bytes

g/@O

Prints:

103
g

Explanation

This was quite fun to figure out. :)

g Pop two implicit zeros from the stack and retrieve the code point at that
 location in the code. That's the 'g' itself, so we're pushing 103.
/ Reflect to SE. Switch to Ordinal. The IP bounces diagonally up and down
 through the code.
O Implicitly convert the 103 to "103" and print it with a trailing linefeed.
 Bounce off the top right corner and move back.
/ Reflect to W/ Switch to Cardinal.
g Push 103 again.
 The IP wraps back to the last column
O Interpret the 103 as a code point and print the corresponding character.
 This prints 'g'. 
@ Terminate the program.

() pushes an empty string to the stack. a "stringifies" it by wrapping it in (...) so after aaa we get (((()))). S prints that string (without the outermost parentheses, so we get only three pairs).

$" contains a " " by default. x9 uses the repetition operator to "multiply" the string by 9.

C (modern Linux), 19 bytes

main(){raise(11);}

Output (with newline):

Segmentation fault

How it works:

SIGSEGV is defined as 11 in /usr/include/asm-generic/signal.h. Therefore, raise(11) raises SIGSEGV, and when SIGSEGV is raised on Linux, all execution stops and Segmentation fault is printed.

20 bytes

main(){raise(2*2);}

Output (with newline):

Illegal instruction

22 bytes

main(){raise(2*3-1);}

Output (with newline):

Trace/breakpoint trap

22 bytes

main(){raise(5*2+5);}

Output (with newline):

User defined signal 1

22 bytes

main(){raise(1?26:0);}

Output (with newline):

Virtual timer expired

24 bytes

main(){raise(12*(1+1));}

Output (with newline):

CPU time limit exceeded

25 bytes

main(){raise(5*5?5*5:0);}

Output (with newline):

File size limit exceeded

25 bytes

main(){printf(raise(8));}

Output (with newline):

Floating point exception

To be pedantic, all of these messages are written by the shell that launched your program, not by your program itself.
@MDXF It really is the shell, not the kernel. You can prove it by running echo 'main(){raise(11);}' | gcc -xc -; echo ./a.out | strace bash, which shows bash making the write call. The exact format varies from shell to shell. Here is where the message is defined within the bash source code. You will not find it anywhere in the Linux kernel outside of documentation.

Pyramid Scheme, 32 bytes

^ ^ 
-^-
^-^
-^-
^-^
-^-
^-^
- -

Explanation

This may not look like pyramid scheme but it is. Each triangle looks like:

 ^
 -

This performs one of three operations

If it has 2 args it pairs them together
If it has 1 arg it returns it
If it has 0 args it returns 0

So at the bottom we have two zeros, those are linked on the next level. On the next level two different pyramids grab the pair and then those pairs are paired together. This continues all the way up the pyramid. When we get to the top we have:

 ((((0,0),(0,0)),((0,0),(0,0))),(((0,0),(0,0)),((0,0),(0,0))))

Pyramid scheme's implicit output converts this to 16 zeros separated by newlines. That's 32 bytes.

Bash, 1 byte:

It sort of outputs a newline...although I don't know if the program gets credit for that or the Bash interpreter.

I'm a bit dubious that this counts, so:

Bash, 21 bytes

x=12345;echo $x$x$x$x

This is really terrible, I know. Are you allowed to call any standard program with Bash?

\$\begingroup\$ Ok. I'm still not sure. Calling almost anything from a bash shell will generate a new line, it's not even the interpreter that's looking at my program that does that (I think). It's just that after doing whatever my program does (which is nothing), the Bash shell (which is essentially a REPL) outputs a blank line. \$\endgroup\$

Pyth, 1 byte

It prints a new line character.

Explanation: k is just a variable initialized to '' (empty string), and by default Pyth prints the values of instructions which do nothing, followed by a new line character. In this case, it prints an empty string and then the new line character.

Test it online! (the online interpreter doesn't show the \n, you will have to install Pyth on your computer to actually see it)
