The Clockwise/Spiral Rule: Mastering Complex C Declarations

This article introduces the 'Clockwise/Spiral Rule,' a clever technique for parsing complex C declarations. By spiraling clockwise through the declaration, replacing elements like arrays, pointers, and functions with their English equivalents, even the most intricate declarations become understandable. The author demonstrates the technique with several examples, from simple pointer arrays to nested function pointers, and shows how to handle `const` and `volatile` keywords. This method offers a practical and intuitive way to decipher confusing C code.
