What is the difference between enums and constants?

What is the difference between enums and constants?

Enums are a way to define a set of named values, while constants are fixed values that do not change.

Can you give me an example of when to use an enum?

Sure! Use an enum for a set of related values, like days of the week, to improve code readability.

And what about constants? When should I use them?

Constants are best for values that remain unchanged throughout the program, like mathematical constants or configuration settings.

Are there any performance differences between using enums and constants?

Generally, enums can be slightly slower due to their additional features, but the difference is often negligible.
