Enum example in C program.

enum-example.c

#include <stdio.h>

int main()
{
enum weekdays{sun, mon, tue, wed, thu=121, fri, sat};

enum weekdays sunday = sun;
enum weekdays friday = fri;

  printf("sunday has the value: %d and friday: %d", sunday, friday);//Here friday has the value 122 because the previous const thu has the value of 121 whilst wed has the value of 3 because sun is initialized to zero.
  
return 0;
