Two-character combinations in character strings 
No.  Description  Example 
1  Dollar sign  $$ 
2  Single quote  $' 
3  Line feed  $L or $I 
4  Newline  $N or $n 
5  Form feed (page)  $P or $p 
6  Carriage return  $R or $r 
7  Tabulator  $T or $t 
 
Tips: 
•  The newline character provides an implementation-independent means of defining the end of 
a line of data for both physical and file I/O; for printing, the effect is that of ending a line of data 
and resuming printing at the beginning of the next line. 
•  The $' combination is only valid inside single quoted string literals.
