                         Specifications for printf()


       Field                   Description

       -       left justify
       +       prefix positive numbers with '+', overrides blank
       space   prefix positive numbers with space
       #       prefix octal or hex with 0, (see manual for Turbo C)
       width   width of output string in total characters, a 0 before
               width causes padding with zeros on left.
       .prec   decimal precision in characters
       size    F       far pointer
               N       near pointer
               h       specifies short
               l       specifies long
               L       long double
       type    c       single character
               d       signed decimal integer
               e       signed exponential, 'e' is output in string
               E       signed exponential, 'E' is output in string
               f       signed floating point in form of sddd.ddd
               g       formats e or f (depends on size), e is output
               G       formats e or f (depends on size), E is output
               i       signed decimal integer
               n       integer pointer
               o       unsigned octal integer
               p       void pointer;  MS C always uses far pointers, in
                       Turbo C, size is dependent on memory model
               s       string pointer
               u       unsigned decimal integer
               x       unsigned integer in lower case hex format
               X       unsigned integer in upper case hex format

       - if width or precision are specified as an asterisk '*', an int
         from the argument list is used as the width or precision. If the
         width is too small the field is expanded.  Example:

               int len = 5;
               char *string = "This is a string"

               printf("%*.*s", len, len, "string");

         is functionally similar to a specification string of "%5.5s"
         which prints a max of 5 characters of the string.
