WebIf you make a Hybrid class object in the main, you see that the Car Constructor is called two times. This is because of the diamond problem.

Two-parent classes with a common base class will now inherit the base class virtually and avoid the occurrence of copies of the base class in the child class ( ClassC here). This is called virtual inheritance. WebHence the ambiguity occurs (diamond prob) But when you are using interfaces, no concept of vTable comes. Because vTable is useful between base and derived class scenario's in calling diff implementations among them. In this case, the interface doesn't gonna contain any implementation and so no vPtr, vTable and hence no diamond problem. Share high schools in ballito
