Code Golf: Code Golf

First, show the shortest possible program that will emit the nine-character string “Code Golf”, without the quotation marks and without anything after the final “f”. Then show the shortest possible program that does the same thing but without itself containing any string or character literals, and without requiring any input or any environment variables or command-line arguments, though the name of the running program can be used.

Extra credit: how big is the executable required to perform the first task? Skip details about any prior compilation steps that might be involved.

ALGOL 68

Works with: ALGOL 68G version Any - tested with release 2.8.3.win32

With Quoted Literals

Source size is 18 bytes; as ALGOL 68G is an interpreter, there isn't a compiled object. The interpreter itself is 2780 K. <lang algol68>print("Code Golf")</lang>

Output:

Code Golf

Without Quoted Literals

Source size is 74 bytes; as noted above, as ALGOL 68G is an interpreter, there isn't a compiled object. The interpreter itself is 2780 K.
Declares and uses a unary operator ! which is effectively an abbreviation for REPR (which converts an INT to a CHAR) and then uses this with the builtin + operator which appends CHARs or STRINGS to form another STRING. <lang algol68>OP!=(INTc)CHAR:REPRc;INTo=111;print(!67+!o+!100+!101+!32+!71+!o+!108+!102)</lang>

Output:

Code Golf

FreeBASIC

With a quoted string, the following weighs in at 12 bytes. <lang freebasic>?"Code Golf"</lang>

For the second task, this is 80 bytes long. <lang freebasic>dim as byte i,a(8)={37,81,70,71,2,41,81,78,72} for i=0 to 8 ?chr(30+a(i)); next</lang>

Both compile to a file 27,016 bytes long.

jq

Works with: jq

Works with gojq, the Go implementation of jq

To skip the newline, the interpreter must be invoked with the -j option:

$ jq -nj '"Code Golf"' | wc -c
       9

For the second task, the following program clocks in at 41 bytes: <lang>[-33,11,0,1,-68,-29,11,8,2|.+100]|implode'</lang>

Extra credit The jq executable on my Mac is 461,864 bytes; gojq's is over 8 times larger.

Raku

Not very interesting, as it's pretty much just standard, non-obscure Raku. The output string is so short, there isn't any easy way to golf it shorter than just printing it directly. 17 bytes. <lang perl6>print </lang>


Output:

Code GolfWren

The shortest possible program (25 bytes) to print the required string is:
<lang ecmascript>System.write("Code Golf")</lang>
The size of the executable needed to run this or indeed any other standalone program (Wren-cli on Linux) is 414,760 bytes. However, if Wren were being embedded in a minimal C program, then the size of the executable would be 17,320 bytes.
If the program itself cannot contain string or character literals, then the shortest program I've been able to come up with (74 bytes including required newline characters) is:
<lang ecmascript>class Code{}
class Golf{}
System.writeAll([Code,String.fromByte(32),Golf])</lang>


Output:

In both cases:

Code Golf

Note that classes (like everything else in Wren) are objects and all objects have a default string representation which in the case of a class is its name.

X86 Assembly

This is 100 bytes long (with CR+LF line endings). More useful than small,
obfuscated source is small executable. This makes a 17-byte .COM file
under MS-DOS. Assemble with: tasm and tlink /t. The xchg instruction is a
single byte (as opposed to a straightforward 2-byte mov ah,9), and it
takes advantage of the high byte of register bp being set to 09h when the
program is started by MS-DOS. 09h selects the "display string" function.
<lang asm>.model tiny

end s</lang>

XPL0

This is 19 bytes long. I hate to say how big the executable is, but it's
54,400 bytes on the Raspberry Pi. Under MS-DOS a version of the compiler
produces an executable as small as 6674 bytes.
