The code you provided is incomplete. The statement `cout` is not complete, so it will result in a compilation error. In order to provide the expected output, you need to complete the statement `cout` by specifying what you want to output.

'ptr' is a pointer to the first element of the array 'arr'. When we add an integer value to a pointer, it moves the pointer forward by that many elements. So, 'ptr + 2' points to the third element of the array. The expression '*(ptr + 2)' dereferences the pointer and gives the value at that memory location, which is 3.
