G conversion character applies to a
long_double
argument. If an h, l, or L appears
with any other conversion character, it is ignored.
5. A character that specifies the type of conversion to be applied.
6. A field width or precision, or both, can be indicated by an asterisk (
*
) instead of a
digit string. In this case, an int argument supplies the files width or precision. The
arguments specifying field width or precision displays before the argument (if any) to
be converted. A negative field width argument is taken as a - flag followed by a posi-
tive field width. A negative precision argument is taken as if it were missing.
