How to clean initialized resources if exception thrown from constructor in c++?
The trick is to use RAII(resource acquisition is initialization) to manage resources.
If you have pointer members then use smart pointers instead of raw pointers which will automagically do the cleanup job once a exception is thrown from constructor.
