The following answers assume compilation using gcc 11.3.0 on ubuntu 22.04, without using any special options and ignoring the warnings that:.
 
The shortest possible program (2826 bytes) to print the required string is: ▼
1. The default return type of 'main' is 'int'; and
<syntaxhighlight lang="c">main(){printfputs("Code Golf");}</syntaxhighlight>▼
 
The size of the executable needed to run this is 15,968960 bytes.▼
2. 'printf' is being implicitly declared (i.e. no explicit #include <stdio.h>).
 
If the program itself cannot contain string or character literals, then the shortest program I've been able to come up with (8248 bytes) is: ▼
▲The shortest possible program (28 bytes) to print the required string is:
▲<syntaxhighlight lang="c">main(){printf("Code Golf");}</syntaxhighlight>
 
<syntaxhighlight lang="c">main(){int ca[]={370x65646f43,90x6c6f4720,2,3,70,33,9,10,0102};formain(int i=0;i<9;++i)printf{puts("%c",c[i]^102a);}</syntaxhighlight>▼
▲The size of the executable needed to run this is 15,968 bytes.
 
The size of the executable needed is now 1615,016992 bytes.▼
▲If the program itself cannot contain string or character literals, then the shortest program I've been able to come up with (82 bytes) is:
 
▲<syntaxhighlight lang="c">main(){int c[]={37,9,2,3,70,33,9,10,0};for(int i=0;i<9;++i)printf("%c",c[i]^102);}</syntaxhighlight>
 
▲The size of the executable needed is now 16,016 bytes.
 
Output in both cases:
