// [flags]

// positive numbers)
//( (space) if no sign is going to be written, a blank space is inserted
// before the value)
//( # used with o, x or X specifiers the value is preceded with 0, 0x
// or 0X respectively for values different than zero. Used with e,
// E and f, it forces the written output to contain a decimal point
// even if no digits would follow. By default, if no digits follow,
// no decimal point is written. Used with g or G the reult is the
// same as with e or E but trailing zeros are not removed)
//
// [width]
// (nbr) minimum number of characters to be printed. if the value to be
// printed is shorter than this number, the result is padded with
// blank spaces. The value is not truncated even if the result is
// larger
// * the width is not specified in the format string, but as an
// additional integer value arguement preceding the argument that
// has to be formatted
//
// [.precision]
// .nbr fot integer specifiers (d,i,o,x,X) - precision specifies the
// minimum number of digits to be written. If the value to be
// written is shorter than this number, the result is padded with
// leading zeros. The value is not truncated even if the result is
// longer. A precision of 0 means that no character is written for
// the value 0. For e, E and f specifiers this is the number of
// digits to be printed after the decimal point. For g and G
// specifiers This is the maximum number of significant digits
// to be printed. For s this is the maximum number of characters
// to be printed. By default all characters are printed until the
// ending null character is encountered. For c type it has no
// effect. When no precision is specified, the default is 1. If the
// period is specified without an explicit value for precision, 0
// is assumed
// .* the precision is not specified in the format string, but as an
// additional integer value argument preceding the argument that
// has to be formated
