Reusing enum values in separate enum types

Question

Is there a way to reuse the same enum value in separate types? I\'d like to be able to something like the following:

enum DeviceState { UNKNOWN, ACTIVE, DISABLED         


        

Answer 1

For those using C++11, you may prefer to use:

enum class Foo

instead of just:

enum Foo

This provides similar syntax and benefits from as namespaces. In your case, the syntax would be:

enum class DeviceState { UNKNOWN, ACTIVE, DISABLED, NOTPRESENT, UNPLUGGED };
DeviceState deviceState = DeviceState::UNKNOWN;

Note that this is strongly typed so you will need to manually cast them to ints (or anything else).
