  printf 
 
    The  standard  function  in  the  {C}  programming 
  language  library  for  printing  formatted  output. 
 
  The  first  argument  is  a  format  string  which  may  contain 
  ordinary  characters  which  are  just  printed  and  "conversion 
  specifications"  -  sequences  beginning  with  '%'  such  as  %6d 
  which  describe  how  the  other  arguments  should  be  printed,  in 
  this  case  as  a  six-character  decimal  integer  padded  on  the 
  right  with  spaces. 
 
  Possible  conversion  specifications  are  d,  i  or  u  (decimal 
  integer),  o  ({octal}),  x,  X  or  p  ({hexadecimal}),  f 
  ({floating-point}),  e  or  E  ({mantissa}  and  {exponent}, 
  e.g.  1.23E-22),  g  or  G  (f  or  e  format  as  appropriate  to  the 
  value  printed),  c  (a  single  character),  s  (a  string),  % 
  (i.e.  %%  -  print  a  %  character).  d,  i,  f,  e,  g  are  signed, 
  the  rest  are  unsigned. 
 
  The  variant  {fprintf}  prints  to  a  given  output  stream  and 
  sprintf  stores  what  would  be  printed  in  a  string  variable.
