Yes, but...pointers are numeric memory addresses (they are like zip codes that tell where your objects are stored in memory). Although you could add two pointers together, the answer is indeterminant and wouldn't serve any purpose.

Most of the financial software like store systems , billing software etc all start with zip code.
It is a very very critical peice of information and a key component in the information retrieval and
processing.

For example when printing bills...all the customer bills corresponding to one zip code are sorted out
and done together ...

For store systems, several things come into picture inventory control, purchasing dept, customer service
etc...everything considers zipcode as critical piece of processing information.
