Question 2
Pointer Subtraction

Answer

* Pointer subtraction (address subtraction) gives the "distance" between two objects.

* These Two objects must be of same type (two objects can be of different base type but in this case their diff makes little sense.)

* The operation is signed Arithmetic

* Depending on the languages and its Implementation, The result is "negative" if the first operand is stored at lower address than the second operand (at higher address.)
