Enumerations

Explore the fundamental concepts of enumerations (enums) in programming. This guide provides an in-depth look into the syntax and usage of enums, utilizing examples such as colors, numbers, and playing cards. Learn how enums can enhance code readability and organization by creating named constants. Discover practical applications, like flipping a coin and tallying results with enum types. Whether you're a beginner or looking to refresh your knowledge, this resource is perfect for understanding how and when to implement enums in your projects.

  1. Enumerations

  2. Your First Enums // syntax enumenum_name {enumerator1, enumerator2, ... enumeratorN}; // example 1 enum color {green, blue, yellow}; // example 2 enum number {one, two, three, four, five}; //example 3 enum {Ace, King, Queen, Jack};

  3. Your First Enums // syntax enumenum_name {enumerator1, enumerator2, ... enumeratorN}; // example 1 enum color {green, blue, yellow}; // example 2 enum number {one, two, three, four, five}; //example 3 enum {Ace, King, Queen, Jack};
