C++ virtual deconstructor
Author
On this recent thread... click jfclavette asks some example questions and one of them is...
- Why should a destructor never be virtual in C++ ?
I was wondering why this is, with my understanding, having a virtual deconstructor would cause the deconstructor of a class that was dirived from this class to be called. Which is really important... But, I didn't know if I was wrong or if this was a trick question.
Thanks for the help
Yeah, my understanding's the same as yours. I thought destructors are necessary for inheritance to work right...
Making a base class destructor non virtual is one way of documenting that you don't want people to derive from your class.

Thanks a lot for the clarification guys... I thought it was too serious to have a trick question but I guess I was wrong.
