Enum | Enumerations(enums) in C | enum in C Programming | enumeration data type in c
An enum (enumeration) in C is a user-defined data type that assigns meaningful names to a set of related integer constants, making the code more readable and maintainable.
Key Concepts
Syntax: Use the enum keyword followed by the enumeration name and a list of identifiers in curly braces.
enum Weekday
{
MONDAY=0,
TUESDAY,
WEDNESDAY,
THURSDAY,
FRIDAY,
SATURDAY,
SUNDAY
};
Values: By default, the first constant (e.g., MONDAY) is assigned the integer value 0, and subsequent constants are incremented by 1 automatically.
Custom Values: You can explicitly assign integer values to any constant, and the subsequent values will increment from the last assigned value.
Why Use Enums?
Enums are typically used to represent a limited set of options or states, such as:
Days of the week or months of the year
Error codes or status codes
Options in a menu or various flags
