hey Sheri,

None of the answers are correct.
Bcoz, The right hand side returns a boolean which u r assigning to a int.... Which doesnt compile.

I think sheri is right
i<<l should become long and cannot be assigned to an int without an explicit cast.>
This is from a mock exam which i noted because I also felt it was a mistake.(Marcus Green II).

i (left shift operator)l becomes a long which cannot be assigned to an int without an explicit cast
