Enumtüüpe

Enumtüüpe, often shortened to enums, are a fundamental data type in many programming languages. They represent a way to define a set of named constants. Think of it as creating a specific, limited list of possible values for a variable. Instead of using abstract numbers or strings, enums provide meaningful labels that improve code readability and reduce the chances of errors. For example, instead of using the integer 0 for "red" and 1 for "blue," you could define an enum called `Color` with members `Red` and `Blue`. This makes your code easier to understand at a glance.

The primary benefit of using enums is enhanced type safety. When a variable is declared as an enum type, it can only hold one of the predefined enum values. This prevents assigning invalid or unintended values, which can lead to bugs. Furthermore, enums can make code more maintainable. If you need to add a new possible value, you simply add a new member to the enum definition, and all parts of the code that use that enum will be aware of the new possibility.

The underlying implementation of enums can vary between languages. Some languages might represent them internally as integers, while others might treat them as distinct types. Regardless of the internal representation, the programmer interacts with them as named constants, offering a clear and structured way to manage a fixed set of related values. They are commonly used for representing states, options, or categories where the number of possibilities is known and limited.
