Singular or plural for enumerations?

Question

Do you use singular or plural for enumerations? I think it makes best sense with plural in the declaration

enum Weekdays
{
    Monday,
    Tuesday,
    Wednesday         


        

Answer 1

In general, I consider an enum definition to be a type definition, with the values of the enum being the different values the type can have; therefore it gets a singular name: enum Weekday { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY }; enum CoffeeSize { SMALL, MEDIUM, LARGE };

Yes. If you do the mental experience of implementing the enums as classes, then the fact that you'd use a singular name for the type should reveal that it makes sense to use singular names for such enums . E.g.,

struct Weekday {};

const Weekday SUNDAY;
const Weekday MONDAY;
const Weekday TUESDAY;

...

void func (Weekday *day)
{
   if (day == &SUNDAY)
       ...
}

For who prefers plurals in enums, would you name that struct Weekdays?
