I think this could work with just two or three variants of a question.
Always ask what's the return value of the function.
1. int foo() { return 8 % 3; }
I don't think non-programmers know what that '%' symbol is, but
programmers of any language would recognize this.
2. int foo() { int x = 8; x++; x++; return x; }
I don't think non-programmers would guess ++ is increment, but
programmers most probably know it.
3. bool foo() { return 42 != 30 };
I don't think non-programmers know what "!=" is.
