Escape Sequences

Escape Sequences

An escape sequence is a special character that displays non-visibly. For example, you can use this type of character to indicate the end of line, that is, to ask the program to continue on the next line. An escape sequence is represented by a backslash character, \, followed by another character or symbol. For example, the escape sequence that moves to the next line is \n.

An escape can be included in single-quotes as in '\n'. It can also be provided in double-quotes as "\n".

The C# language recognizes other escape sequences.

Escape Sequence	Name	Description
\a	Bell (alert)	Makes a sound from the computer
\b	Backspace	Takes the cursor back
\t	Horizontal Tab	Takes the cursor to the next tab stop
\n	New line	Takes the cursor to the beginning of the next line
\v	Vertical Tab	Performs a vertical tab
\f	Form feed
\r	Carriage return	Causes a carriage return
\"	Double Quote	Displays a quotation mark (")
\'	Apostrophe	Displays an apostrophe (')
\?	Question mark	Displays a question mark
\\	Backslash	Displays a backslash (\)
\0	Null	Displays a null character

To use an escape sequence, you can also first declare a char variable and initialize it with the desired escape sequence in single-quotes.
