Re: Interview Questions
A good IDE should tell you that you inherit from a class that does not have a virtual destructor. I'd personally be surprised if the compiler didn't at least warn you as well. For the sake of documentation, I actually usually do this. Not so much in my own code, but when I am working with a team of people.
Code:
/* final */ class nonpolymorphic {
...
That way at a quick glance, you know whether or not a class may be inherited from. It's actually a little strange that C++ has no keyword for this like other languages.
@OReubens Wouldn't making all of your destructors virtual mean that all of your objects have vtables?
Also, lol, why does the text input box not have word wrap?
