When should I use switch vs if in C++?

When should I use switch vs if in C++?

You should use a switch statement when you have multiple discrete values to compare against a single variable. It's often cleaner and more efficient than using multiple if-else statements.

Can you give me an example of when to use each?

Sure! Use switch for menu options or command selection. Use if-else for range checks or complex conditions.

Are there performance differences between the two?

Yes, switch can be faster for many cases since it may use jump tables, while if-else chains evaluate conditions sequentially.

What about readability? Which one is easier to read?

Switch statements can be more readable for many cases with many options, while if-else is better for complex conditions.

Is there a limit to how many cases I can have in a switch?

There's no strict limit in C++, but having too many cases can make the code harder to manage and understand.
