What is enum ??

Answer 1

An enumeration is a user-defined data type that consists of integral constants. To define an enumeration, keyword enum is used.

enum season { spring, summer, autumn, winter };

Here, the name of the enumeration is season.

And, spring, summer and winter are values of type season.

By default, spring is 0, summer is 1 and so on. You can change the default value of an enum element during declaration (if necessary).
enum season { spring = 0, summer = 4, autumn = 8, winter = 12 };
