Beyond Duff's Device: Clifford's Hidden Gem for C/C++ Developers
C 프로그래머가 반드시 알아야 할 Clifford's Device의 우아한 활용법
Why it matters
While Duff's Device remains famous for exploiting case fall-through, Clifford's Device offers an elegant but overlooked solution for temporary code disabling. By combining if(0) with labels and goto statements, developers can create protected code blocks that only execute when explicitly invoked, enabling cleaner control flow patterns and safer code management in complex C/C++ applications.
