@Prashant. I am not getting this,

when we do, c-b why we got 1 as answer, likewise when we do *c-a why we got 4 as answer ?

Here i modified to programme to see the address, i think c-b should be 8 and *c-a should be 16. Where i am going wrong ?

3347544000 is nothing the base address of the array b.

3347544008 is nothing the 2nd element address of the array b.  which is contain by c after c++.

3347544008 - 3347544000 = 8 but we know pointer take 8 byte here . so divide by size of pointer is needed. so 8/8= 1
