Character combinations consisting of a backslash (\) followed by a letter or by a combination of digits are called "escape sequences." To represent a newline character, single quotation mark, or certain other characters in a character constant, you must use escape sequences. An escape sequence is regarded as a single character and is therefore valid as a character constant. 

Escape sequences are typically used to specify actions such as carriage returns and tab movements on terminals and printers. They are also used to provide literal representations of nonprinting characters and characters that usually have special meanings, such as the double quotation mark ("). The following table lists the ANSI escape sequences and what they represent.

Note that the question mark preceded by a backslash (\?) specifies a literal question mark in cases where the character sequence would be misinterpreted as a trigraph. See Trigraphs for more information.

Escape Sequences
Escape Sequence  Represents  
\a
 Bell (alert)
 
\b
 Backspace
 
\f
 Formfeed
 
\n
 New line
 
\r
 Carriage return
 
\t
 Horizontal tab
 
\v
 Vertical tab
 
\'
 Single quotation mark
 
\"
 Double quotation mark
 
\\
 Backslash
 
\?
 Literal question mark
 
\ooo
 ASCII character in octal notation
 
\xhh
 ASCII character in hexadecimal notation
 
\xhhhh
 Unicode character in hexadecimal notation if this escape sequence is used in a wide-character constant or a Unicode string literal. 

For example, WCHAR f = L'\x4e00' or WCHAR b[] = L"The Chinese character for one is \x4e00".
 

Microsoft Specific 

If a backslash precedes a character that does not appear in the table, the compiler handles the undefined character as the character itself. For example, \c is treated as an c.

2 Alphabetic escape sequences representing nongraphic characters in the execution
character set are intended to produce actions on display devices as follows:
\a (alert) Produces an audible or visible alert. The active position shall not be changed.
\b (backspace) Moves the active position to the previous position on the current line. If
the active position is at the initial position of a line, the behavior is unspecified.
\f ( form feed) Moves the active position to the initial position at the start of the next
logical page.
\n (new line) Moves the active position to the initial position of the next line.
\r (carriage return) Moves the active position to the initial position of the current line.
\t (horizontal tab) Moves the active position to the next horizontal tabulation position
on the current line. If the active position is at or past the last defined horizontal
tabulation position, the behavior is unspecified.
\v (vertical tab) Moves the active position to the initial position of the next vertical
tabulation position. If the active position is at or past the last defined vertical
tabulation position, the behavior is unspecified.
