64 bit enum in C++?

Question

Is there a way to have a 64 bit enum in C++? Whilst refactoring some code I came across bunch of #defines which would be better as an enum, but being greater than 32 bit ca

Answer 1

Enum type is normally determined by the data type of the first enum initializer. If the value should exceed the range for that integral datatype then c++ compiler will make sure it fits in by using a larger integral data type.If compiler finds that it does not belong to any of the integral data type then compiler will throw error.

Edit: However this is purely depended on machine architecture
