strange behavior

Hi!  I am wondering why these two modules behave differently


Module[{ans = ""},
  For[i = 1, i < 10, i++,
    ans = InputString["Enter a String"];
    Print[ans]
    ]
  ]


and


Module[{ans = ""},
  For[i = 1, i < 10, i++,
    ans = InputString["Enter a String"]
    Print[ans]
    ]
  ]


One prints out a bunch of extraneous Null's

Also is there anyway to type variable in Mathematica  i.e. declare i to be and
integer or string or whatever.


Thanks for any help you can give.  
Sorry for the simpleness of these questions.

Thanks
