The SmartPtr class by Stefan Tchekanov works nicely for homogenous class objects but it does not allow assignment between base and derived class pointers. I am presenting here a simple template class that performs reference counting garbage collection and supports subclass pointers. The example that follows explains the use of this class: class B {… […]
