It distinguishes between syntactic errors (easy to find) and semantic/logic errors (difficult to find). Debugging is the process of finding and fixing

“Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.” — Brian Kernighan Author(s): Ben Shneiderman Published in: Proceedings of the

These papers treat debugging as a logical reasoning problem. Therefore, if you write the code as cleverly
