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.

\r Carriage Return 13
\" Quotation Mark (Double Quote) 34
\' Apostrophe (Single Quote) 39
\? Question Mark (?) 63
\\ Backslash (\) 92
