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.
The comma operator separates expressions (which have value) in a way analogous to how the semicolon terminates statements, and sequences of expressions are enclosed in parentheses analogously to how sequences of statements are enclosed in braces: [1] (a, b, c) is a sequence of expressions, separated by commas, which evaluates to the last expression c, while {a; b; c;} is a sequence of ...
All about the Oxford comma, including when it may or may not be necessary.
A comma code is a type of prefix-free code in which a comma, a particular symbol or sequence of symbols, occurs at the end of a code word and never occurs otherwise. [1] This is an intuitive way to express arrays. For example, Fibonacci coding is a comma code in which the comma is 11.
Some people use the Oxford comma (also known as the Harvard or serial comma). This is a comma before "and" or "or" at the end of a series, regardless of whether it is needed for clarification purposes. For example: X, Y, and Z (with an Oxford comma) X, Y and Z (without an Oxford comma)
A stylistic depiction of values inside of a so-named comma-separated values (CSV) text file. The commas (shown in red) are used as field delimiters. A delimiter is a sequence of one or more characters for specifying the boundary between separate, independent regions in plain text, mathematical expressions or other data streams.
A block is a grouping of code that is treated collectively. Many block syntaxes can consist of any number of items (statements, expressions or other units of code) – including one or zero. Languages delimit a block in a variety of ways – some via marking text and others by relative formatting such as levels of indentation.
The serial comma (for example the comma before and in "ham, chips, and eggs") is optional; be sensitive to possible ambiguity arising from thoughtless use or thoughtless avoidance, and be consistent within a given article. Avoid comma splices. Picture captions should not end in a full stop (a period) unless they are complete sentences.
