What's the difference between these two enum declarations - C? -

i've started learning c , have reached point of enums. enum preferred alternative define / const int, correct?

what's difference between these 2 declarations?

#include <stdio.h>  // method 1 enum days {     monday,     tuesday };  int main() {     // method 1     enum days today;     enum days tomorrow;      today    = monday;     tomorrow = tuesday;      if (today < tomorrow)         printf("yes\n");      // method 2     enum {monday, tuesday} days;      days = tuesday;     printf("%d\n", days);      return 0; } 

an enumeration should preferred on #define/const int when want declare variables can take on values out of limited range of related, mutually exclusive values. days of week good example, bad example:

enum aboutme {     myage = 27,     mynumberoflegs = 2,     myhousenumber = 54 }; 

going code example; first method declares type called enum days. can use type declare many variables like.

the second method declares single variable of type enum { ... }. cannot declare other variables of type.
