c++ dynamic_cast error handling

Question

Is there any good practice related to dynamic_cast error handling (except not using it when you don\'t have to)? I\'m wondering how should I go about NULL and bad_cast it can th

Answer 1

bad_cast is only thrown when casting references

dynamic_cast< Derived & >(baseclass)

NULL is returned when casting pointers

dynamic_cast< Derived * >(&baseclass)

So there's never a need to check both.

Assert can be acceptable, but that greatly depends on the context, then again, that's true for pretty much every assert...
