No, it's not. Maybe that's how your C compiler implements it, but that's
not what C defines. I've used C interpreters where the pointers weren't
actual memory locations.
You can add 10 to it and look at whatever is 10 bytes ahead in
memory.
No, you can't. C doesn't guarantee that adding 10 to a pointer won't
crash your program. Indeed, there are any number of architectures where
this isn't so. (And I don't mean indirecting it. I mean at the actual
addition.)
Is a Java reference an actual memory location? Can you find the
size of a list of Java data structures, add something to the reference,
and look ahead in memory? I'm pretty sure you can't.
No, you can't.

It's not feature creep if you put it
at the end and adjust the release date.
