I'm having a bit of trouble with this program I'm working on. I have a base class, we'll call it Base, and two nearly identical Derived classes, only one of which is relevant. I created a pointer (Base *BP), and pointed it to Derived &DO. I need to downcast it so that it can access the Derived class's member functions (or, rather, just one, called setType(string), but that's the idea). I spent hours troubleshooing and researching casting, but can't quite figure out what's wrong. Any help would be appreciated.
Here's basically what it looks like:
Base *BP; BP = new Derived(); Derived *DO = dynamic_cast<Derived *>(BP); BP->setType("hello");
This results in getting a "error: class Base has no member named setType"
Thank you for your time.
