  sir Good Day :

  PLT Schemes
  i used this utility functions i used it to manipulate the stream such as map and filter.

  > ( define (inc x) (+ 1 x))
  >(define int (make-stream 0 inc )
  >(define sqr x ))
  > (stream-print (stream-map int sqr) 10)
     ( 0 1 4 9 16 25 36 49 64 81 ) ...... output
  >( stream-print (stream-filter int odd?) 15 )
  ( 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29)

  i have to used the utility functions below 

  1. (stream-map stream op)
  2.(stream-filter stream ok? )

  " i used the accessor stream-current and stream-next to access the succeeding stream.


  Thanks a lot i hope you give us ideas on this :)

  More Power ......
