Escape Sequences in Literals
String and character literals provide an escape mechanism that allows express character codes that would otherwise not be allowed in the literal. An escape sequence consists of a backslash character (\) followed by one or more other characters. The same sequences are valid in both character and string literals.
The complete set of escape sequences is as follows:
Escape sequence meaning:
\\ Denotes a backslash (\) character \' Denotes a single-quote (') character \" Denotes a double-quote (") character \n Denotes a line feed (LF) character \r Denotes a carriage return (CR) character \t Denotes a horizontal tab (HT) character \f Denotes a form feed (FF) character \b Denotes a backspace (BS) character \<octal> Denotes a character code in the range 0 to 255.
The <octal> in the above consists of one, two or three octal digits ('0' through '7') which represent a number between 0 and 255 (decimal).
