%04x -4-digit hex number with leading zeros

%*d - Runtime width specifier (e.g. printf(“%*d%s”, required_space, value) )

%.*s - Print a substring (e.g. printf(“%.*s”, requred_len, string) )

%.0d - Print nothing for zero

%#x - Print a leading 0x

See the MSDN documentation for printf format specification.
