This makes sense because a pointer of any type is just a memory addresss. [X] But what about inheritance where one pointer can really be two pointers? For example, if class D derives from class B, the a pointer to a B can also possibly be a pointer to a D. [X] The business of casting is just a compile time check on the correctness of our code. Correct? (2) Can we assume that sizeof(pointer)=sizeof(int)? -- ---------------------------------- Siemel B.
