5. Memory Management When using inheritance and dynamic memory allocation, virtual destructors are vital for proper memory management. Overriding the destructor in derived classes ensures that resources allocated by the base and derived classes are correctly deallocated, which prevents memory leaks and ens...
As we have seen above that when we make the call to function (involved in overriding), the child class function (overriding function) gets called. What if you want to call the overridden function by using the object of child class. You can do that by creating the child class object in ...
