In this video Chili teaches us how to figure out what our polymorphic pointers are actually pointing to (aka "type discovery"). Just note that although we can do this, it is generally a weaksauce way to go about things. Virtual functions are 1000% more hype than type discovery bullshit. Oh yeah, we also finally see all the C++ style casts united.
Topics Covered
-
dynamic_cast<T*>anddynamic_cast<T&> -
const_cast - Overview of all C++ style casts
- RTTI with
typeid() - The
type_infoclass

Source Code
Note that the code for this video is in a different branch called "casting". You will not find it in the master branch.
