Defining Enums

An enumeration (enum) is a user-defined type that groups a set of named integer constants.

Instead of remembering that 0 means Monday and 1 means Tuesday, you give those numbers readable names. This makes code clearer and harder to get wrong.

You declare an enum with the enum keyword, a tag name, and a list of names in braces.

Each name becomes a constant you can use anywhere an integer is expected.
