followed by integer number or *, or neither that specifies precision of the conversion. (Note: This is the minimum width: The value is never truncated.) If the value of the argument is negative, it results with the - flag specified and positive field width. In the case when * is used, the width is specified by an additional argument of type int, which appears before the argument to be converted and the argument supplying precision if one is supplied. The result is padded with space characters (by default), if required, on the left when right-justified, or on the right if left-justified.
For other conversions using this flag results in undefined behavior. For integer numbers it is ignored if the precision is explicitly specified. 0 : for integer and floating point number conversions, leading zeros are used to pad the field instead of space characters.See the table below for exact effects otherwise the behavior is undefined. # : alternative form of the conversion is performed.space: if the result of a signed conversion does not start with a sign character, or is empty, space is prepended to the result.+: the sign of signed conversions is always prepended to the result of the conversion (by default the result is preceded by minus only when it is negative).-: the result of the conversion is left-justified within the field (by default it is right-justified).(optional) one or more flags that modify the behavior of the conversion:.Each conversion specification has the following format:
The format string consists of ordinary multibyte characters (except %), which are copied unchanged into the output stream, and conversion specifications. If there are more arguments than required by format, the extraneous arguments are evaluated and ignored.
If any argument after default argument promotions is not the type expected by the corresponding conversion specifier, or if there are fewer arguments than required by format, the behavior is undefined.
