I don't think you can be downvoted, there's no downvote button

Users with enough karma can downvote comments.

A beautiful example of Cunningham's Law! :)

I downvoted just because I thought it wasn't great advice. It makes the code incompatible with C++ compilers, and being able to compile C with C++ compiler is often useful.

Also... it felt kind of... unnecessary? to tell someone who is making a compiler how to write basic code in the language they're writing a compiler for. It almost felt like telling an overweight medical student/doctor that he should avoid eating fatty foods.

Writing C code so won't compile with a C++ compiler is gods work.

Because C++ is why C can't have nice things.
