C++ Enumeration

Enum in C++ is a data type that contains fixed set of constants.

It can be used for days of the week (SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY and SATURDAY) , directions (NORTH, SOUTH, EAST and WEST) etc. The C++ enum constants are static and final implicitly.

C++ Enums can be thought of as classes that have fixed set of constants.

Points to remember for C++ Enum

• enum improves type safety
• enum can be easily used in switch
• enum can be traversed
• enum can have fields, constructors and methods
• enum may implement many interfaces but cannot extend any class because it internally extends Enum class
