The real world is complicated—far more complicated than just whole numbers, numbers with fractions, Boolean values, and characters. In order to model it, C provides various mechanisms for custom and complex data types. For the next eight chapters, we are going to explore various ways that our intrinsic data types can be extended and combined to more closely match the real world.
The first of these extensible data types is enumerated types. These are groups of values that are related; but, we don't really care about their values—we differentiate each item in the group by its name. The value corresponding to that name is irrelevant to us; the significance lies in its unique name within the group of enumerated ...
