const vector implies const elements?

Question

Does const vector mean that its elements are constas well?

Answer 1

Yes, a const vector provides access to its elements as if they were const, that is, it only gives you const references. In your second function, it's not the objects of type A that are const, but pointers to them. A pointer being const does not mean that the object the pointer is pointing to is const. To declare a pointer-to-const, use the type A const *.
