Max and min values in a C++ enum

Question

Is there a way to find the maximum and minimum defined values of an enum in c++?

Answer 1

No. An enum in C or C++ is simply a list of constants. There is no higher structure that would hold such information.

Usually when I need this kind of information I include in the enum a max and min value something like this:

enum {
  eAaa = 1,
  eBbb,
  eCccc,
  eMin = eAaaa,
  eMax = eCccc
}
