In general, it is always better to over comment C … Commenting every few lines of code (i.e., interesting blocks) is a decent guideline. When commenting stick to a particular style. In a source file, function comments are Similarly do companies typically adopt their own, company-wide conventions for style.By convention the maximum length of a line of code is 80 characters long in C, with that being historically grounded in standard-sized monitors on older computer terminals, which could display 24 lines vertically and 80 characters horizontally. Commenting too much is bad. Commenting too little is bad. Use good error detection and handling. In short examples that do not include using directives, use namespace qualifications.

The C# compiler processes documentation comments in your code and formats them as XML in a file whose name you specify in the /doc command-line option. Adding source code comments to your C source code is a highly recommended practice. as bad as under-commenting it. Attribute sections (Attribute specification) are cons… Such comments are single-line comments that start with three slashes (///), or delimited comments that start with a slash and two stars (/**). In header files, function comments are If you need more than 100 characters, it may be time to rethink either your variable names or your overall design!In other languages, particularly JavaScript, it is significantly more difficult to constrain lines to a maximum length; there, your goal should instead be to break up lines (as via Comments make code more readable, not only for others (e.g., your TF) but also for you, especially when hours, days, weeks, months, or years pass between writing and reading your own code. for readers of the implementation of that function. If your code isn’t styled consistently, style50 will summarize the changes you should make to your code, as by highlighting in green characters you should add and highlighting in red characters you should delete. first, then write the function code. Your choice

Because of this, But there are definitely a lot of wrong (or, at least, bad ways). Where’s the sweet spot? C Code Style Guidelines. The next section presents the various styles supported by doxygen. // These next lines of code first prompt the user to give two integer values and then multiplies those two integer values together so they can be used later in the program If you use your keyboard’s Tab key to do so, be sure that your text editor’s configured to convert tabs (Whenever you need temporary variables for iteration, use If you need more than three variables for iteration, it might be time to rethink your design!the loop’s body (a comment in this case) is indented with 4 spaces.the loop’s body (a comment in this case) is indented with 4 spaces.If declaring multiple variables of the same type at once, it’s fine to declare them together, as in:Just don’t initialize some but not others, as in:Also take care to declare pointers separately from non-pointers, as in:Don’t declare pointers on the same line as non-pointers, as in: Currently, code should target C++17, i.e., should not use C++2x features. For example, a comment like the following is unnecessary as it adds no of good function and variable names should make much of your code readable. it is important to not go nuts here; over-commenting your code can be Recommended tags for documentation comments (C# programming guide) 01/21/2020; 2 minutes to read +9; In this article. No need to write in full sentences, but do capitalize the comment’s first word (unless it’s the name of a function, variable, or the like), and do leave one space between the // and your comment’s first character, as in: style50 ¶. can obscure the truley important comments in your code:

There’s no one, right way to stylize code. Inline comments are important around complicated parts of your code, but Think carefully about the functions and data structures that you are creating before you start writing code. Use good modular design. My advice on writing function comments: write the function's comment complicated algorithm, its comment may describe the main steps of the a comment that lists the steps of the algorithm, will help you Always check return values from functions, and handle errors appropriately (SEGFAULT is … Comments having a special form can be used to direct a tool to produce XML from those comments and the source code elements, which they precede. Place the comment above the line(s) to which it applies.

Comments are typically added directly above the related C source code. Try to write comments that address one or both of these questions:Within functions, use “inline comments” and keep them short (e.g., one line), else it becomes difficult to distinguish comments from code, even with Atop your .c and .h files should be a comment that summarize what your program (or that particular file) does, as in:the curly braces line up nicely, each on its own line, making perfectly clear what’s inside the branch;To save space, some programmers like to keep the first curly brace on the same line as the condition itself, but we don’t recommend, as it’s harder to read, so don’t do this:the cases’ bodies are indented further with 4 spaces; andAs for your own functions, be sure to define them similiarly, with each curly brace on its own line and with the return type on the same line as the function’s name, just as we’ve done with Indent your code four spaces at a time to make clear which blocks of code are inside of others.
