C++ Enum: Scoped vs Unscoped

What is the difference between scoped and unscoped enums in C++?

Scoped enums (enum class) provide better type safety and avoid name clashes, while unscoped enums are more traditional.

Can you give me an example of each type?

Sure! An unscoped enum looks like this: enum Color { Red, Green, Blue };. A scoped enum would be: enum class Color { Red, Green, Blue };.

Why should I use scoped enums over unscoped ones?

Scoped enums prevent implicit conversions to integers and require qualification, which enhances code clarity and safety.

Are there any performance differences between the two?

Generally, there are no significant performance differences. The choice is more about safety and clarity in your code.
