The fact that you're asking this indicates that you're at a stage in 
your exposure to Ada when you will probably have no need whatsoever for 
access types. Access types are rarely needed in Ada unless you're 
creating a dynamic data structure, and even then you don't need pointer 
arithmetic.

If you have some problem for which you think access types and pointer 
arithmetic are required, let us know what the problem is and I suspect 
we can show you why you're wrong, and what the Ada way is. In the 
extremely rare case that you're not wrong, we can show you what to do.
