It reads a square bracket (the
[), then a converts a decimal integer and stores the result inn, then reads a closing square bracket. The brackets themselves are simply skipped over, they’re not part of the conversion.You might be thinking of the character group conversion specifier, which looks like
%[...], where the ellipsis should be replaced by characters to accept. See the manual page for details.
