Call a non-const member function from a const member function

Question

I would like to know if its possible to call a non-const member function from a const member function. In the example below First gives a compiler error. I understand why it

Answer 1

I found myself trying to call a non-const member function that was inherited, but was actually const because of the API I was using. Finally I settled on a different solution: re-negotiate the API so that the function I inherit is properly const.

It won't always be possible to negotiate changes to others' functions, but doing so when possible seems cleaner and nicer than needing to use const_cast and it benefits other users as well.
