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)|
|\n||Newline (Line Feed)||10|
|\"||Quotation Mark (Double Quote)||34|
|\'||Apostrophe (Single Quote)||39|
|\?||Question Mark (?)||63|
