Indeed.

   bool is_even(int* valPtr) {
      assert(valPtr != nullptr);
      return *valPtr % 2;
    }

Does not do what you think it does with nullptr. A major game engine [0] has a toggle to enable asserts in shipping builds, mostly for this reason

This is a very "Dr Dr it hurts when I do this" "Don't do that" one it must be said.

I'm sorry, but what exactly is the problem with the code? I've been staring at it for quite a while now and still don't see what is counterintuitive about it.

    There's nothing wrong with it. It does exactly what you think it does when passed null.
