An Unbiased View of C++ homework help online



For any foundation course Base, contacting code may well try to damage derived objects via tips to Base, which include when utilizing a unique_ptr. If Base’s destructor is public and nonvirtual (the default), it could be accidentally termed with a pointer that truly factors into a derived object, wherein circumstance the behavior of the attempted deletion is undefined.
