So *(arr+5) will be 6th element (as we start array from 0,1,2..) =600
now *(*(arr+5)+2) means 3rd element in array of address 600. Thus we get 602 here
Here i assumed int as 1 so 600+ 2*1 =602 but also even considering int=2 we get 604 (600,602,604,..) still index is 3rd in that array.(0,1,2..)
*(*(*arr+5)+2)+1) will take us to array at 602. Now we go till index 1 from zero and value here is 2 by
arr[5][2][1].
Hope everyone get this!
