Format specifiers

This table shows the format specifiers used by scanf and printf. The "Format specifier" is the sequence passed as the formatting string argument; "Characters matched" gives the format of the sequence sought or printed, with a hyperlink to the section on literals which applies to that format; "Argument type" gives the type of expression expected by printf and of pointer expected by scanf.
