The implementation depth of the index is uncovered (making sure that it would be misused), and i outlives the scope with the loop, which might or might not be intended. The reader are unable to know from this article just this section of code.
In this exceptional case, you may make the destructor community and nonvirtual but Plainly document that additional-derived objects should not be utilized polymorphically as B’s. This really is what was done with std::unary_function.
