Mastering the C Clockwise Spiral Rule for Parsing Declarations

I introduce a simple three-step technique called the Clockwise Spiral Rule that allows any C programmer to mentally parse even the most complex declarations. By starting with the unknown element and moving in a spiral direction to resolve tokens like arrays, pointers, and functions, you can translate confusing syntax into clear English statements. This method handles everything from basic pointers to intricate function signatures involving const and volatile qualifiers.

There is a technique known as the Clockwise Spiral Rule which enables any C programmer to parse in their head any C declaration!
