In C++ both these enum types have an "underlying type" which is just an integer. That's the type you're really getting for most purposes.
In terms of syntax specifically you can cast (in C++ specifically static cast) integers to an enumerated type. This makes mechanical sense to C++ because of the compatible "underlying type" but as a direct consequence you don't have the kind of type safety these exercises are relying on.
Notice that if I cast 1.234 to an integer, C++ says that's 1. It does know that cast doesn't mean "just change the type but keep the same bits" and yet, that's exactly what happens for enum.
