Pointer incrementation and subtraction are done in terms of memory blocks
and not addresses of memory.
For example,
int *p;
p++;
The pointer here jumps to the next integer location and not the next address
in memory.
Similarly,pointer subtraction will give the difference in indexes and not
the memory addresses.
If you try subtracting an integer pointer and a float pointer, it will be an
error.
