I have a class that is derived from another class. I want to be able to catch and re-throw the exception(s) thrown by the derived class’s constructor in my derived class’s constructor.
There seems to be a solution for this in C#:

But since there is no such keyword as C#’s baseI have no idea how and if this is possible in C++.
Is there a solution? This would enable me to reuse quite a lot of code.
>Solution :
There is a pretty good example of this here: Exception is caught in a constructor try block, and handled, but still gets rethrown a second time
Ultimately, if you manage to catch an exception in the derived class the only thing you should do is to either rethrow that exception or throw a new one. This is because if the base class constructor does not complete then the derived class will be in an undefined state and you should not use it.
