comment-layout-and-formatting

To format code comments with proper indentation, align them with the code they describe using the same indentation level. This ensures comments do not obscure the visual hierarchy and helps readers understand the program logic structure.

The best way to handle spacing is to place at least one blank line before each comment to separate it from the code. Optionally, use blank lines both before and after comments for a better visual effect that is easier to scan.

You do not need a specific coding standard to normalize comment indentation. The core principle is that having a consistent convention for spacing and alignment is more important than the specific details of the convention itself.

Comment formatting applies across different programming languages by applying universal rules for indentation level, blank lines, and alignment with code blocks. This ensures consistent comment structure and documentation of logic across various coding standards.

Using blank lines both before and after comments provides a better visual effect and makes code easier to scan, but it consumes more display space. Applying a consistent spacing convention across your codebase is more critical than the specific spacing choice.

End-of-line comments require different formatting because standard comment indentation rules apply to standalone comments. Aligning block comments separately ensures they do not obscure the visual indentation structure of the code they describe.
