/*

The register Storage Class
The register storage class is used to define local variables that should be stored 
in a register instead of RAM.
 This means that the variable has a maximum size equal to the register 
 size (usually one word) and can't have the unary '&' operator applied to it 
 (as it does not have a memory location).

{
   register int  miles;
}
The register should only be used for variables that require quick access 
such as counters. It should also be noted that defining 'register' 
does not mean that the variable will be stored in a register. 
It means that it MIGHT be stored in a register depending on hardware and 
implementation restrictions.
