I've written many tens of thousands of lines of C, but retired 15 years ago. The two best books I know are: 1. C: A Reference Manual, by Harbison and Steele. https://www.amazon.com/Reference-Manual-Samuel-P-Harbison/dp/013089592X/ref=dp_ob_title_bk https://www.amazon.com/Reference-Manual-Samuel-P-Harbison/dp... 2. The C Puzzle Book, by Alan Fueur. https://www.amazon.com/Puzzle-Book-Alan-R-Feuer/dp/0201604612 https://www.amazon.com/Puzzle-Book-Alan-R-Feuer/dp/020160461... Harbison and Steele has much better explanations than K&R. The Fueur book taught me a lot about C declarations. Declarations are that part of C language that is them most unnecessarily difficult. You asked about a slightly different question, best practices. But in the real world you'll run into a lot of code that practices below that level.
