Not only does the comment help the reader understand the code in the current and referenced methods, it is helpful for determining whether the code is still needed and how to test it. I’ve seen students in upper-division computer science classes add a comment to each closed brace to indicate what block is ending: if (x > 3) Many junior programmers write too many comments because they were trained to do so by their introductory instructors. Rule 1: Comments should not duplicate the code The rest of this article explains each of these rules, providing examples and explaining how and when to apply them. Rule 9: Use comments to mark incomplete implementations. Rule 7: Include links to external references where they will be most helpful. A search will lead me to a question and its marked as a duplicate of another. Rule 6: Provide links to the original source of copied code. Questions marked as duplicate that are 'bigger' than the question they purport to duplicate closed I find this on a semi-regular basis from searches in Google, DuckDuckGo, and Stack Overflows search. Rule 5: Explain unidiomatic code in comments. Here are some rules to help you achieve a happy medium. A bad comment is worse than no comment at all. While it's easy to measure the quantity of comments in a program, it's hard to measure the quality, and the two are not necessarily correlated. Rule 4: Comments should dispel confusion, not cause it. While there are many resources to help programmers write better codesuch as books and static analyzersthere are few for writing better comments. Rule 3: If you can’t write a clear comment, there may be a problem with the code. Rule 2: Good comments do not excuse unclear code. Rule 1: Comments should not duplicate the code. Here are some rules to help you achieve a happy medium: While all of these points are true, it would be a mistake to go to the other extreme and never write comments. 'Cropit Landscaping has been providing exceptional installations of hardscape and landscaping custom designs throughout Ottawa and surrounding areas. You are, on the other hand, guaranteed that the computer is doing exactly what your code is telling it to.Your compiler doesn’t check your comments so there is no way to determine that comments are correct.Writing and then maintaining comments is an expense.Explore all available options and convert. A bad comment is worse than no comment at all. What is PSD to HTMLWe convert your designs to high quality, cross-browser compatible, valid HTML/ XHTML / CSS markup. While it’s easy to measure the quantity of comments in a program, it’s hard to measure the quality, and the two are not necessarily correlated. While there are many resources to help programmers write better code-such as books and static analyzers-there are few for writing better comments. We find some programs harder to understand than others, and we look to comments to help us make sense of them. Compilers and interpreters ignore comments and find all syntactically correct programs equally easy to understand. Famed MIT professor Hal Abelson said: “Programs must be written for people to read and only incidentally for machines to execute.” While he may have purposely understated the importance of running code, he is spot on that programs have two very different audiences.
