What are the differences between nested if-else statements and switch statements?

Nested if-else statements allow for multiple conditions to be checked in a sequence, while switch statements are used for a single variable that can take multiple values.

Can you give me an example of each?

Sure! For nested if-else, you might check if a number is positive, negative, or zero. For a switch, you could check the day of the week and return a specific message for each day.

Which one is more efficient?

Switch statements can be more efficient for a large number of conditions, as they can be optimized by the compiler, while nested if-else can become cumbersome.

Are there any scenarios where one is preferred over the other?

Yes, if you have a simple condition with many possible values, a switch is often clearer. For complex conditions, nested if-else might be better.
