What is <C. C.> and why is so important?

Clean Code

It refers to an approach to writing code that seeks to produce high-quality software, easy to understand and maintain. The central idea behind the concept of clean code is that the source code should be expressive, readable, and understandable, both for the writer and for other developers who may work on it in the future.
