It's part of the type yet it's also a unique identifier. That's the whole thing with east or west const. const int * is a ~~immutable~~ mutable pointer that points to ~~mutable~~ immutable memory. int *const is a ~~mutable~~ immutable pointer that points to ~~immutable~~ memory. int const * is the same type as the first example, a ~~immutable~~ mutable pointer that points to ~~mutable~~ immutable memory.

Same stuff applies to references which makes it easier to think of the variable owning the * or & as if you want that pointer or reference to be const it has to go after.

Edit:I am a moron who managed to get it exactly backwards :|
