The enum in this case could have a std::pair<int, float> as fundamental type instead.

Wouldn't that be simpler and more flexible, as this class (in this case std::pair) could provide added functionality, e.g. suitable constructors.

sizeof an enum is essentially a sizeof its underlying type, so it should be the sum of sizeof of each type.

 

C and D are valid.

if the compiler can ( and should ) compare them and optimize the storage, then it could be optimized.

However then you would ensure that operator== is implemented for it to be used.
