How to use enums as flags in C++?

Oct 25, 2013 See the question and my original answer on StackOverflow

Note if you are working in Windows environment, there is a DEFINE_ENUM_FLAG_OPERATORS macro defined in winnt.h that does the job for you. So in this case, you can do this:

enum AnimalFlags
{
    HasClaws = 1,
    CanFly =2,
    EatsFish = 4,
    Endangered = 8
};
DEFINE_ENUM_FLAG_OPERATORS(AnimalFlags)

seahawk.flags = CanFly | EatsFish | Endangered;
