The assignment in line 3 should not error, as the array is of the parent of MyDerived, in accordance with the above rule of equivalence of pointers under polymorphism. Of course, one explanation is that handles are not synonymous to pointers. And the workaround is to deploy the cell array.
WebMar 8, 2024 · Virtual functions and polymorphism. A virtual function is a special type of function that, when called, resolves to the most-derived version of the function that exists between the base and derived class. This capability is known as polymorphism.A derived function is considered a match if it has the same signature (name, parameter types, and … WebNow let's see how we can achieve polymorphism using operator overloading.

WebPolymorphism is the ability of objects of different classes to be treated as if they are the same type. Polymorphism allows for greater flexibility and modularity in code, as it allows a single method or function to handle objects of different types. For example, consider a "Drive" method that takes a Vehicle object as a parameter.

Also, a base class pointer can point to the objects of the base class as well as to the objects of the derived class. In the above code, base class pointer ‘bptr’ contains the address of object ‘d’ of the derived class. barter restaurantWebNow, while run time polymorphism may exhibit dynamic (or late) binding.
