What are some alternatives to nested if-else statements in programming?

There are several alternatives to nested if-else statements, such as using switch statements, polymorphism, or even lookup tables.

Can you explain how a switch statement works?

Sure! A switch statement evaluates an expression and executes code blocks based on matching case values, which can be cleaner than nested if-else.

What about using polymorphism? How does that help?

Polymorphism allows you to define a common interface for different classes, enabling you to call methods without needing to know the specific class type.

Are there any performance benefits to using these alternatives?

Yes, using alternatives like switch statements or polymorphism can improve readability and maintainability, which can indirectly enhance performance.
