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

  enum My_enum
    {
       FIRST_VALUE = 0,

       MY_VALUE1,
       MY_VALUE2,
       ...
       MY_VALUEN,

       LAST_VALUE
    };

after definition, My_enum::LAST_VALUE== N+1
