Line 12 creates an istream_iterator
that’s capable of extracting (inputting) int
values from the standard input object cin
. Line 14 dereferences iterator inputInt
to read the first integer from cin
and assigns that integer to number1
. The dereferencing operator *
applied to iterator inputInt
gets the value from the stream associated with inputInt
; this is similar to dereferencing a pointer. Line 15 positions iterator inputInt
to the next value in the input stream. Line 16 inputs the next integer from inputInt
and assigns it to number2
.
