Do C++ enums Start at 0?

Question

If I have an enum that does not assign numbers to the enumerations, will it\'s ordinal value be 0? For example:

enum enumeration { ZERO,
                


        

Answer 1

from § 7.2, p 165

. If the first enumerator has no initializer, the value of the corresponding constant is zero
