What are the benefits of using const and final in programming?

What are the benefits of using const and final in programming?

Using const and final helps improve code readability, maintainability, and performance by preventing unintended changes.

Can you give me an example of how to use const in a function?

Sure! In C++, you can declare a constant variable like this: const int maxUsers = 100; This ensures maxUsers cannot be modified.

What about final in Java? How does it work?

In Java, using final with a variable means it cannot be reassigned. For example, final int maxUsers = 100; makes maxUsers immutable.

Are there any performance benefits to using these keywords?

Yes, using const and final can lead to optimizations by the compiler, as it knows certain values won't change.

What are some common mistakes developers make with const and final?

Common mistakes include misunderstanding scope, using them inappropriately, or not leveraging their benefits for code clarity.
