Vegard: new page
2020-03-13T08:51:16Z
<p>new page</p>
<p><b>New page</b></p><div>== C ==<br />
<br />
Set the executable bit on the following polyglot C/shell source file:<br />
<br />
<source lang="C"><br />
#if 0<br />
gcc -Wall $0 && exec ./a.out; exit<br />
#endif<br />
<br />
#include <stdio.h><br />
<br />
int main(int argc, char *argv[])<br />
{<br />
printf("Hello world!\n");<br />
return 0;<br />
}<br />
</source><br />
<br />
This is my favourite version because:<br />
* readable (e.g. no multiline comments)<br />
* minimal boilerplate<br />
* only runs the program if it compiled successfully<br />
* exits with 1 if there was an error<br />
<br />
