How to remove constness of const_iterator?

Question

As an extension to this question Are const_iterators faster?, I have another question on const_iterators. How to remove constness of a const_iterator

Answer 1

This may not be the answer you wanted, but somewhat related.

I assume you want to change the thing where the iterator points to. The simplest way I do is that const_cast the returned reference instead.

Something like this

const_cast(*it);
