An enum is a user-defined data type in C++ that provides an efficient way to represent a group of related constants of an integer type. It allows the programmer to assign meaningful names to these constants, making the code more readable and maintainable.
Enums are particularly useful when you have a set of values that have a specific meaning or order, such as days of the week, months of the year, or error codes. By using an enum, you can easily refer to these values by their symbolic names rather than their numeric equivalents.
