Great tutorial! You should use abstract instead of virtual for the Go method in this case though. This would also mean the class Vehicle has to be abstract as well.

Thankyou for this, correct me if I’m wrong but can you also have vehicle as as abstract class and have a abstract method with no body which can then be overridden by the other classes ?

yes you are correct but then you HAVE to override it not only can

This is an example of run-time polymorphism. There's also compile-time polymorphism such as method overloading.

My instincts when hearing “polymorphism” is to think cat changes into dog. Car changes to boat. Not cat is also an animal, or car is also a vehicle.

Ok but how does it actually work? If it’s like casting where each object is cast to their base class then wouldn’t they lose all their properties that were defined in the child class but not the base?

If you want to inherit from more than one class, you just use the comma "," operator?
