The following escape sequences can be used to define certain special characters within strings:

Escape Sequence	Description
\'	Single quote
\”	Double quote
\\	Backslash
\nnn	Octal number (nnn)
\0	Null character (really just the octal number zero)
\a	Audible bell
\b	Backspace
\f	Formfeed
\n	Newline
\r	Carriage return
\t	Horizontal tab
\v	Vertical tab
\xnnn	Hexadecimal number (nnn)

An example of this is contained in the following code (which assumes that the newline character generates complete newlines, i.e. on Unix systems):

    printf( "This\nis\na\ntest\n\nShe said, \"How are you?\"\n" );

which would display

    This
    is
    a
    test

    She said, "How are you?"
