What is the primary purpose of debugging?

The primary purpose of debugging is to find and fix code errors. When writing code, it's common to inadvertently include mistakes—these might be syntax errors, logical errors, or runtime errors. Debugging is a systematic process that developers use to identify these errors, understand their causes, and correct them to ensure that the program runs as intended. Effective debugging is essential for delivering quality software, as it helps ensure that all functionalities work correctly and efficiently.

The other choices pertain to different aspects of software development. Improving the user interface focuses on enhancing user experience rather than correcting errors in the code itself. Enhancing audio effects relates specifically to sound manipulation but does not address the general issue of code correctness. Creating complex algorithms is a task in programming that may occur after debugging, but it is not the purpose of the debugging process itself.
