Escape Sequences

Escape sequences, sometimes called "digraphs", make it possible to include non-printable characters, or characters that by themselves have special meaning into a character or string literal. Although these are all typed in as two characters starting with a backslash (\), they are technically just a single character (a single 8-bit code is represented by them, just like any other character). Below are some of the escape sequences you are most likely to encounter.

Escape Sequence	Character It Represents	ASCII Value (decimal)
\a	BELL (alert)	7
\b	Backspace	8
\t	Horizontal Tab	9
\n	Newline (Line Feed)	10
\v	Vertical Tab	11
\f	Form Feed	12
\r	Carriage Return	13
\"	Quotation Mark (Double Quote)	34
\'	Apostrophe (Single Quote)	39
\?	Question Mark	63
\\	Backslash (\)	92
\0	NUL (null)	0
