How can I improve the performance of enums in C++?

How can I improve the performance of enums in C++?

To improve enum performance in C++, consider using scoped enums (enum class) for better type safety and optimization.

What are the benefits of using enum class over traditional enums?

Enum class provides better scoping, avoids name clashes, and allows for type-safe comparisons, enhancing performance.

Are there any specific scenarios where enums can cause performance issues?

Yes, using enums in switch statements with many cases can lead to performance hits; consider using hash maps for large sets.

Can I use bitwise operations with enums?

Yes, you can use bitwise operations with enums if they are defined as powers of two, allowing for efficient flag management.
