C/C++ Create an enum with negative values, without having to number it

Start with INT_MIN on top like this:

#include <limits.h>

enum fruits
{
  orange = INT_MIN,
  lemon, 
  ...
}

Per “5.2.4.2.1 Sizes of integer types ” and/or “Annex E/1” of the C11 Standard INT_MIN is at least -32767.

INT_MIN gets defined by including <limits.h>.
