The allowed operations on Pointers are:
Assignment to other pointers of the same type
Addition and subtraction of a pointer to an integer
Assignment of the value 0
Comparison to the value 0

Other than the above operations other operations are not allowed with pointers.

To explain you in brief I have given below some examples on operations that are not allowed with pointers.
Multiplication or division on a pointer
Addition or subtraction of two pointer values
Assignment of a value other than 0 to a pointer
