What are the best practices for using switch-case in C++11?

In C++11, it's important to use switch-case effectively. Some best practices include using enum for case values, ensuring each case ends with a break statement to prevent fall-through, and keeping cases simple and focused.

Can you explain why using enum is beneficial?

Using enum improves code readability and maintainability. It allows you to define meaningful names for your case values, reducing the risk of errors and making the code easier to understand.

What should I do if I have many cases?

If you have many cases, consider using a map or a function pointer array instead of a switch-case. This can help keep your code cleaner and more efficient.

Are there any performance considerations?

Yes, while switch-case can be efficient, if you have a large number of cases, a lookup table or binary search might be more performant. Always profile your code to find the best approach.
