Question

What is use of enum class ? I know that it makes enum element as strong cast and we cannot use the element of enum without class name i.e. enum name... but what is use case of this?

any problem has been solved by this or what is the advantages for doing the same functionality?

1. enum class does not propagate enumerators outside of its scope, so there is no name clashing.
2. You are able to forward its declaration.
