In C, enum (short for enumeration) is a user-defined data type that lets you assign names to a set of integer constants — making your code clearer and easier to manage. ??

? Basic Syntax

c
enum #include enum () {    enum enum typedef enum {    RED,    GREEN,    BLUE} Color;Color c = GREEN;

Now you don’t need to write enum Color, just Color.

? Behind the Scenes

Enums are just integers under the hood:

c
enum enum Mood myMood = SAD;printf("%d\n", myMood); // Output: 1

? Why Use Enums?

• Replaces magic numbers ????

• Improves readability & maintainability

• Great for states, modes, types, etc.
