3.2.1 Escapes

The escapes that ‘-printf’ and ‘-fprintf’ recognise are:

\a

Alarm bell.

\b

Backspace.

\c

Stop printing from this format immediately and flush the output.

\f

Form feed.

\n

Newline.

\r

Carriage return.

\t

Horizontal tab.

\v

Vertical tab.

\\

A literal backslash (‘\’).

\0

ASCII NUL.

\NNN

The character whose ASCII code is NNN (octal).

A ‘\’ character followed by any other character is treated as an ordinary character, so they both are printed, and a warning message is printed to the standard error output (because it was probably a typo).
