How do nested if-else statements work in real-world applications?

Nested if-else statements allow for complex decision-making in programming. They enable you to evaluate multiple conditions.

Can you give me an example of where I might use them?

Sure! For instance, in an online shopping application, you might check if a user is logged in, then if they have items in their cart, and finally if those items are in stock.

What happens if I have too many nested if-else statements?

Having too many nested if-else statements can make your code hard to read and maintain. It's often better to use switch statements or separate functions.

Are there any best practices for using nested if-else?

Yes! Keep your conditions simple, limit nesting levels, and consider using early returns to simplify your logic.
