Histogram

--------------------------------------------------------
  1 ****(4)
  2 ******(6)
  3 ***********(11)
  4 *****************(17)
  5 **************************(26)
  6 *************************(25)
  7 *******(7)
  8 ***(3)
  9 (0)
 10 *(1)
--------------------------------------------------------

basically above is what my prgram needs to do.. im missing something somewhere any help would be great :)
