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, there is no way to find the maximum and minimum defined values of any enum in C++. When this kind of information is needed, it is often good practice to define a Last and First value. For example,

enum MyPretendEnum {    Apples,    Oranges,    Pears,    Bananas,    First = Apples,    Last = Bananas }; 

There do not need to be named values for every value between First and Last.

Answer 2

No, not in standard C++. You could do it manually:

enum Name {    val0,    val1,    val2,    num_values }; 

num_values will contain the number of values in the enum.
