Base class to subclass conversion

[mehmetned]

How do we convert from base class object to sub class object in c++?

[Stephen Hewitt]

A cast will do the trick (pBase is a pointer to the base class). The fastest way if you're sure it's safe: static_cast<Dervied*>(pBase); The safest way (runtime checked): dynamic_cast<Dervied*>(pBase); You could use Boost's polymorphic_downcast[^] for a solution that uses dynamic_cast in debug builds and static_cast in release builds.
