C2y: Hitting the Ground Running

The C programming language continues evolving beyond C23 with C2y introducing several new features. Key additions include the countof operator (renamed from lengthof based on community feedback), if declarations similar to C++, new escape sequences with octal deprecation, case ranges for switch statements, additional bit manipulation utilities, and labeled breaks for better loop control. These improvements address long-standing pain points in C development, particularly around array sizing, nested loop control, and bit operations, while maintaining backward compatibility through careful deprecation strategies.
