What are the best practices for using switch-case statements?

When using switch-case statements, it's important to ensure that each case is distinct and that you include a default case to handle unexpected values.

Can you explain why a default case is important?

A default case acts as a fallback option, ensuring that your program can handle unexpected inputs gracefully without crashing.

Should I use switch-case over if-else statements?

It depends on the situation. Use switch-case for multiple discrete values, as it's often cleaner and more readable than multiple if-else statements.

Are there any performance considerations?

Yes, switch-case can be more efficient than if-else chains in some languages, especially when dealing with many cases, as it can use jump tables.
