Iterating Backwards in C
Summary
David Priver explains why iterating a C array backward with an unsigned index is safer and simpler than common signed-loop approaches. He shows the pitfalls of using for(i = count - 1; i >= 0; i--) and presents a concise, correct pattern using for(size_t i = count; i--). The article also discusses wrap-around behavior of unsigned integers and releases its code into the public domain.
