In the C programming language, an escape sequence is specially delimited text in a character or string literal that represents one or more other characters to the compiler.It allows a programmer to specify characters that are otherwise difficult or impossible to specify in a literal.
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".
The programming language is augmented with natural language description details, where convenient, or with compact mathematical notation. The purpose of using pseudocode is that it is easier for people to understand than conventional programming language code, and that it is an efficient and environment-independent description of the key ...
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 ...
