Some characters, like the escape character \, also called 'backslash" and the string delimiter ", commonly called double-quote have a special meaning in the context of strings. In order to display them literally, they must be preceded by a \. Any use of \ that is not followed by a special character has a non-literal interpretation. For example, \n prints a newline, that is, it moves the position of the cursor to the next line. The tab character is expressed as \t. The backslash itself can be expressed as \\.
