Certain special characters are represented as escape sequences. An escape sequence begins with a \ (backslash) followed by an alphanumeric character. For example, the \n escape sequence represents the newline character. Note that the two characters of an escape sequence are construed as a single character. Here's a complete list of the escape sequences in C++:
\a /*alert (bell)*/
\b /*backspace*/
\f /*formfeed*/
\n /*newline*/
\r /*carriage return*/
\t /*horizontal tab*/
\v /*vertical tab*/
\\ /*backslash*/
\? /*question mark*/
\' /*single quote*/
\" /*double quote*/
\000 /*octal number*/
\xhh /*hexadecimal number*/
