Are comments in code necessary?
Good comments compliment your code, while bad ones pull readers away from the main points. Before putting any comments, ask yourself whether it would serve any purposes rather than distract people from comprehending your program. Good codes have rhythm while mediocre codes have a lot of pauses.
Why is it important to add comments to your program?
Commenting involves placing Human Readable Descriptions inside of computer programs detailing what the Code is doing. Proper use of commenting can make code maintenance much easier, as well as helping make finding bugs faster. Further, commenting is very important when writing functions that other people will use.
Do you put comments before or?
Always place a comma before or when it begins an independent clause, but if it begins a dependent clause, don’t. People often get muddled about whether to place a comma before conjunctions like and, so, because, and or.
Is it bad to comment your code?
Commenting code is on the generally-recognized list of code smells. But unlike most of the others on the list, comments are not always bad. Generally speaking, you should strive to minimize comments and let the code speak for itself, but it is just as important to include comments when the code cannot.
Do you put comments above or below code?
In the US, at least, the de facto standard is commenting either before the code or on the same line following the code. Writing your comments after the related code invites a drug test, a psychiatric evalutation, and/or a date with a pair of pliers and a blow torch.
Should commented code be removed?
28 Answers. Generally, code that is removed should not be commented, precisely because it clutters the codebase (and, why would one comment on something that doesn’t exist?). Your defect tracking system or source control management tools are where such comments belong.
When do you not need to put a comment in code?
Most coders would chuckle and move on, ignoring the code smell. There are also times when you come across a comment that is redundant. If the code is already simple and obvious, there’s no need to add a comment. Like, don’t do this nonsense:

Why do you put clarification comments in your code?
Clarification comments are intended for anyone (including your future self) who may need to maintain, refactor, or extend your code. Often, a clarification comment is a code smell. It tells you that your code is too complex. You should strive to remove clarification comments and simplify the code instead because, “good code is self-documenting.”
How to write a single line comment in C?
First of all, we should be aware that comments are the description written in the source code within some special characters so as to get ignored by the compiler while running the code. In C and C++ programming, we can write a single line comment by using // (double slash) and multi-line comment within /*….*/
