Code Golf: Code Golf
First, show the shortest possible program that will emit the nine-character string 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 literal strings or requiring any input.
Extra credit: how big is the executable required to perform the first task? Skip details about any prior compilation steps that might be involved.
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 Golf
Wren
Well, this has no quotation marks and there's nothing after the final "f" but it's a bit lengthy at 76 characters (79 if you count the implicit \n at the end of the first three lines). Note that Wren's single pass compiler allows the last line though it does nothing.
<lang ecmascript>class Code{}
class Golf{}
System.writeAll([Code,String.fromByte(32),Golf])
Golf</lang>
- Output:
Code Golf
To print the string "Code Golf" with the quotation marks but with no quotation marks in the script itself would require a minimum of 90 characters (92 including the \n's).
<lang ecmascript>class f{}
for(c in[-66,-33,11,0,1,-68,-29,11,8,2,-66])System.write(String.fromByte(c+100))
f</lang>
- Output:
"Code Golf"
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
.code
org 256
s:xchg ax,bp
mov dx,offset m
int 33
ret
m db "Code Golf$"
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.
