That is not true. This program prints 2 when compiled under Turbo Pascal:

Wow!
Usually if you add 1 to a pointer of type t, then sizeof(t) gets added
to the value of the pointer. So if p points at an array of byte, p+1
would point at the next element of the array, 1 byte after p. But if p

Then you can automatically calculate the amount:
