Enum in C Language

In C language, an enum is a user-defined data type that consists of a set of named integer constants. An enum declaration defines a new data type with a fixed set of possible values.

Here’s an example of an enum declaration:

enum Color {
    RED,
    GREEN,
    BLUE
};

In this example, we’ve defined a new enum type called Color with three possible values: RED, GREEN, and BLUE. Each value corresponds to an integer constant, with RED being assigned the value 0, GREEN being assigned the value 1, and BLUE being assigned the value 2.

You can use an enum type to declare variables, like this:

enum Color favorite_color = GREEN;

In this example, we’ve declared a variable called favorite_color with the enum type Color, and we’ve initialized it to the value GREEN.

enum types are often used to make code more readable and maintainable by giving names to values that might otherwise be represented by obscure integer constants.
