The double slash is used by Rexx as a modulo operator, and Python (starting in version 2.2) uses a double slash for division which rounds (using floor) to an integer. In Raku the double slash is used as a "defined-or" alternative to ||. A dot and slash ./ is used in MATLAB and GNU Octave to indicate an element-by-element division of matrices.
In computer programming, leaning toothpick syndrome (LTS) is the situation in which a quoted expression becomes unreadable because it contains a large number of escape characters, usually backslashes ("\"), to avoid delimiter collision.
In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. [3]Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth ...
Escape characters are part of the syntax for many programming languages, data formats, and communication protocols. For a given alphabet an escape character's purpose is to start character sequences (so named escape sequences ), which have to be interpreted differently from the same characters occurring without the prefixed escape character.
In the most SQL dialects the double dash (--) can be used instead. Esoteric languages. Many esoteric programming languages follow the convention that any text not executed by the instruction pointer (e.g., Befunge) or otherwise assigned a meaning (e.g., Brainfuck), is considered a "comment".
Both forms are actively used. Microsoft .NET (for example, the method new Uri(path)) generally uses the 2-slash form; Java (for example, the method new URI(path)) generally uses the 4-slash form. Either form allows the most common operations on URIs (resolving relative URIs, and dereferencing to obtain a connection to the remote file) to be ...

Typing "DIR/W" gave the "wide" option to the "DIR" command, so some other method was needed if one actually wanted to run a program called W inside a directory called DIR). Except for COMMAND.COM , all other parts of the operating system accept both characters in a path , but the Microsoft convention remains to use a backslash, and APIs that ...
