6 Working Standards Your key contributions in this class will be working source programs Your key contributions in this class will be working source programs Part of that work is documentation, usually in the form of comments Part of that work is documentation, usually in the form of comments Make sure you do comment, not what is evidently visible from the source, but share your thoughts you went through when you wrote your source. Make sure you do comment, not what is evidently visible from the source, but share your thoughts you went through when you wrote your source. For example, when you write code: For example, when you write code: Index ++;// increment the index All readers can see that you increment the index. Don’t bother saying that you increment it. We all know. Detail, what the index is used for, what the next element so identified means, what is behind it? All readers can see that you increment the index. Don’t bother saying that you increment it. We all know. Detail, what the index is used for, what the next element so identified means, what is behind it?

7 Working Standards Include in your comments your name, the date last modified, a description of the project Include in your comments your name, the date last modified, a description of the project Include the class, school, name of the project Include the class, school, name of the project Also, if you rely on other sources (books, internet, advisors) do share which source you are using Also, if you rely on other sources (books, internet, advisors) do share which source you are using When updating or upgrading your program, ensure that the new source and the comments you also update do correspond When updating or upgrading your program, ensure that the new source and the comments you also update do correspond
