The correct answer to this has already been given  no  you can t give the name of an enum  only it s value   Nevertheless  just for fun  this will give you an enum and a lookup-table all in one and give you a means of printing it by name   main c    include  Enum h   CreateEnum          EnumerationName          ENUMValue1          ENUMValue2          ENUMValue3    int main void        int i      EnumerationName EnumInstance   ENUMValue1          Prints  ENUMValue1         PrintEnumValue EnumerationName  EnumInstance           Prints         ENUMValue1        ENUMValue2        ENUMValue3             for  i 0 i lt 3 i                  PrintEnumValue EnumerationName  i             return 0      Enum h    include  lt stdio h gt   include  lt string h gt    ifdef NDEBUG  define CreateEnum name            typedef enum                     VA ARGS           name   define PrintEnumValue name value   else  define CreateEnum name            typedef enum                     VA ARGS           name        const char Lookup  name                  VA ARGS     define PrintEnumValue name  value  print enum value Lookup  name  value  void print enum value const char  lookup  int value    endif   Enum c   include  Enum h    ifndef NDEBUG void print enum value const char  lookup  int value        char  lookup copy      int lookup length      char  pch       lookup length   strlen lookup       lookup copy   malloc  1 lookup length  sizeof char        strcpy lookup copy  lookup        pch   strtok lookup copy            while  pch    NULL                if  value    0                        printf   s n  pch               break                    else                       pch   strtok NULL      -                value--                       free lookup copy      endif   Disclaimer  don t do this

As a string  no  As an integer   d   Unless you count   static char  enumStrings          filler 0 s to get to the first value                                     enum0    enum1                                      filler for hole in the middle   0                                    enum2    enum3                 printf  The value is  s n   enumStrings thevalue      This won t work for something like an enum of bit masks  At that point  you need a hash table or some other more elaborate data structure

I had the same problem    I had to print the color of the nodes where the color was  enum col   WHITE  GRAY  BLACK    and the node  typedef struct Node   col color      I tried to print node- gt color with printf   s n   node- gt color   but all I got on the screen was  null  n   The answer bmargulies gave almost solved the problem   So my final solution is   static char  enumStrings       WHITE    GRAY    BLACK    printf   s n   enumStrings node- gt color
