What is enumerated data type give example?

What are enumerated types used for?

What is the advantage of using enumerated data type in C?
Advantages of Enumerated Data Type: Makes program more readable to the fellow developers. Makes program more manageable while dealing enum type of variables. Using enumerators reduces programming error.
Why is enum used?
Enums are used when we know all possible values at compile time, such as choices on a menu, rounding modes, command line flags, etc. It is not necessary that the set of constants in an enum type stay fixed for all time. In Java (from 1.5), enums are represented using enum data type.
What are basic data types in C?

What is enumeration in C?
