What are the benefits of using a preprocessor?

Using a preprocessor can enhance code readability, reduce redundancy, and enable conditional compilation. It allows you to write cleaner and more maintainable code.

Can you give me an example of how a preprocessor improves code?

Sure! For instance, in C/C++, you can use #define to create constants. This way, if you need to change a value, you only update it in one place.

Are there any downsides to using preprocessors?

Yes, while preprocessors can simplify code, they can also make debugging more complex and may lead to less portable code if not used carefully.

What languages commonly use preprocessors?

Languages like C, C++, and Sass for CSS commonly use preprocessors. They help manage complexity in larger codebases.

How do preprocessors affect performance?

Preprocessors themselves don't affect runtime performance, but they can optimize the code before compilation, potentially leading to more efficient final output.
