Don’t use
reinterpret_cast– either usestatic_castordynamic_cast. If you’re sure that the pointer is to exactly that derived class object usestatic_cast, otherwise usedynamic_cast(that will require the base class to be polymorhic) and check the result to ensure that the pointer is indeed to the class you want.
