C++: Enum vs Const

What is the difference between enum and const in C++?

In C++, an enum is a user-defined type that consists of a set of named integral constants, while const is a keyword used to define constants that cannot be modified.

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

Sure! Use enum when you have a set of related constants, like days of the week. For example: enum Days { Sunday, Monday, Tuesday }; This makes your code more readable.

Are there any performance differences between using enum and const?

Generally, there are no significant performance differences. Both are optimized by the compiler, but enums can provide better type safety.

Can I use enum values in switch statements?

Yes, enums are often used in switch statements, making the code cleaner and easier to manage.
