  • Since nobody dared to take on C since this was posted, here's my attempt. It fulfils the "doesn't crash" criteria (though returns an unspecified value from the program).
  • Disclaimer: I couldn't get `_Imaginary` to work in gcc and clang doesn't even support complex numbers. Therefore I included the keyword inside a string literal, so that I won't get any unfair advantage against someone who can manage to get it working on some compiler.

Since nobody dared to take on C since this was posted, here's my attempt. It fulfils the "doesn't crash" criteria (though returns an unspecified value from the program).
