How can I debug type casting errors in C++?
An example of an AI chatbot conversation about debugging type casting errors in C++.
I'm having trouble with type casting errors in my C++ code. Can you help me debug it?
Of course! Could you share the specific error message you're encountering and the relevant code snippet?
I'm getting an error that says 'invalid cast from type A to type B'. Here's the code: B* b = dynamic_cast<B*>(a);
It looks like the object 'a' is not of type 'B' or a derived class. Make sure 'A' is a polymorphic type with virtual functions.
Ah, I see! I forgot to add a virtual destructor in class A. Thanks for the tip!
No problem! Adding a virtual destructor should resolve the issue. Let me know if you need further assistance!
