Do we really need “enum class” in C++11?

Question

When we have,

struct E { enum E_ { HELLO }; }; // \'E\' is inheritable

then why do we need,

enum class E { HELLO };  // \'E         


        

Answer 1

Besides what was already mentioned, an advantage of enum class is better type safety - the enum class enumerators don't convert implicitly to integers.
