Most languages support multi-line block (a.k.a. stream) and/or single line comments. A block comment is delimited with text that marks the start and end of comment text. It can span multiple lines or occupy any part of a line. Some languages allow block comments to be recursively nested inside one another, but others do not.
In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.
Comments are a form of human-readable metadata, and lengthy comments can disrupt the flow of code. This can be the case either for a long comment for a short section of code, such as a paragraph to explain one line, or comments for documentation generators, such as Javadoc or XML Documentation. Code folding allows one to have long comments, but ...
Block comments in Perl are considered part of the documentation, and are given the name Plain Old Documentation (POD). Technically, Perl does not have a convention for including block comments in source code, but POD is routinely used as a workaround. PHP. PHP supports standard C/C++ style comments, but supports Perl style as well. Python
Haskell, like Python, has the off-side rule. It has a two-dimension syntax where indenting is meaningful to define blocks (although, an alternate syntax uses curly braces and semicolons). Haskell is a declarative language, there are statements, but declarations within a Haskell script. Example:
Users unlock new privileges with an increase in reputation like the ability to vote, comment, and even edit other people's posts. [14] As of March 2024 Stack Overflow has over 23 million registered users and has received over 24 million questions and 35 million answers. [15]
• Comments shouldn't harass, abuse, or threaten anyone's personal safety or property. • Don't post content that promotes, encourages or incites acts of international or domestic terrorism. • Don't post profanity, obscenities, abusive language, or otherwise objectionable content.
Syntax highlighting is one strategy to improve the readability and context of the text; especially for code that spans several pages. The reader can easily ignore large sections of comments or code, depending on what they are looking for. Syntax highlighting also helps programmers find errors in their program.
