What are enumerations?

Question :

What are enumerations?

They are a list of named integer-valued constants.

Example:enum color { black , orange=4, yellow, green, blue, violet };This declaration defines the symbols ―black‖, ―orange‖, ―yellow‖, etc. to have the values ―1,‖ ―4,‖ ―5,‖ … etc. The difference between an enumeration and a macro is that the enum actually declares a type, and therefore can be type checked.
