- java: How can I do dynamic casting of a variable from one type to . . .

- c++ - When should static_cast, dynamic_cast, const_cast, and . . .
The C-style casts can do virtually all types of casting from normally safe casts done by static_cast<> () and dynamic_cast<> () to potentially dangerous casts like const_cast<> (), where const modifier can be removed so the const variables can be modified and reinterpret_cast<> () that can even reinterpret integer values to pointers
