Comparison of data types

I have a warning 'comparison between enum and const enum'.

I tried using static_cast<>.The warning is resolved.but is it really
safe at runtime.

Seconded, but I would like to add that you should probably use
const_cast to cast the non-const enum to const before comparing instead
of using static_cast.
