Obscured or badly structured code is hard to understand, maintain, or reuse regardless of comments. Bad code should be improved, not explained. Reading the code itself is the only way to be absolutely positive about what the code does; therefore, the code should be made as readable as possible. Using comments to duplicate information in the code is a bad idea for several reasons. First, it is unnecessary work that decreases productivity. Second, it is very difficult to correctly maintain the duplication as the code is modified.
