C++: Const vs Enum

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

In C++, const is used to define constant variables, while enum is used to define a set of named integer constants.

Can you give me an example of how to use both?

Sure! You can define a const like this: const int maxSize = 100; and an enum like this: enum Color { Red, Green, Blue };.

When should I use enum instead of const?

Use enum when you have a fixed set of related constants, as it improves code readability and maintainability.

Are there any performance differences between using const and enum?

Generally, there are no significant performance differences, but enum can provide better type safety in certain contexts.
