First of all — you know this — const_iterator is different from iterator const, in exactly the same way that const int * is different from int *const. Not very likely, the foo() is possible to call for const objects of type X, that's the primary purpose of it in this context. It also makes the object const for duration of the method call, so you cannot write to members or call non-const methods, so it's more of static compilation-time const enforcement tool than anything else. This is my understanding of non-const reference, const reference and their relationships with lvalue/rvalue. Please help to review whether it is correct and feel free to correct me.

So this would be valid too: int n = 5; const int * p = &n; Since a const function promises not to modify the internal state of the object, then we’re not breaking it.
