Answer 4:
So here we are point the 0th location with ptr1
next ptr2 is initialized with ptr1+3 means ptr2 will point element
at 3rd location which is 1000.5
so it will print 1000.5
now we subtract 2 pointers it will give distance
so ptr2 is at 3 and ptr1 is at 0
so 3-0=3
so it will print 3
next we are increamenting ptr2 so it will increase 1000.5 to
1001.5
Answer 5:
1000.5 will replaced with 1.5; as ptr2+1 will gives next
element
Answer 6:
As it will give size of point as arr will pointer as we are passing
it functions
so it will give 8 and size of arr[0] is 4 so 8/4=2 so it will print
only 2 locations
