break;

case BLUE:
color_name = "BLUE";
break;
}
printf("%s\n", color_name);
}

With a main function defined as follows (for example):

int main(){
enum color chosenColor;
printf("Enter a number between 0 and 2");
scanf("%d", (int*)&chosenColor);
printColor(chosenColor);
return 0;
}

Example 2

(This example uses designated initializers which are standardized since C99.)

enum week{ MON, TUE, WED, THU, FRI, SAT, SUN };

static const char* const dow[] = {
[MON] = "Mon", [TUE] = "Tue", [WED] = "Wed",
[THU] = "Thu", [FRI] = "Fri", [SAT] = "Sat", [SUN] = "Sun" };

void printDayOfWeek(enum week day)
{
printf("%s\n", dow[day]);
}

The same example using range checking:

enum week{ DOW_INVALID = -1,
MON, TUE, WED, THU, FRI, SAT, SUN,
DOW_MAX };

static const char* const dow[] = {
[MON] = "Mon", [TUE] = "Tue", [WED] = "Wed",
[THU] = "Thu", [FRI] = "Fri", [SAT] = "Sat", [SUN] = "Sun" };

void printDayOfWeek(enum week day)
{
assert(day > DOW_INVALID && day < DOW_MAX);
printf("%s\n", dow[day]);
}
