Question

How do you iterate over an enumeration in C?

Answer 1

To iterate over an enumeration, you can use a for loop. Here's an example that prints all the months:

enum Month {
  JANUARY,
  FEBRUARY,
  MARCH,
  APRIL,
  MAY,
  JUNE,
  JULY,
  AUGUST,
  SEPTEMBER,
  OCTOBER,
  NOVEMBER,
  DECEMBER
};

int main() {
  enum Month currentMonth;

  for (currentMonth = JANUARY; currentMonth <= DECEMBER; currentMonth++) {
    printf("Month: %d\n", currentMonth);
  }

  return 0;
}
