Enums

An enum defines a type consisting of a set of named integer constants, making code more readable than using raw numbers to represent a fixed set of options, such as days of the week or states in a state machine. By default, enum values start at 0 and increase by one for each subsequent name, though explicit values can be assigned. Enums are just integers under the hood, so C does not prevent assigning an out-of-range integer to an enum variable.
