Enum: Definition, Benefits, and Usage in Programming

An enum is a data type in computer programming that allows a programmer to define a set of named values. Enums are used to represent a finite set of possible values that a variable can take, such as 'days of the week' or 'colors'. In many programming languages, enums are implemented as an integer type, where each named value is assigned a unique integer value. Enums can be useful for making code easier to read and understand, and for preventing errors caused by typos or other mistakes when using literals.
