Here take is a pointer local to fn main() and array3[10] is local to fn modify. So array3's entire locations are not visible to main(). "return array3" will retun only the reference of the first element of the array. So the pointer will store only one value 3(the first value in array3) in address "take".
The problem here is the scope of array3. If you declare array3 as a global variable then you will get what you are in need of.
