But we ran into a problem. Developers were able to create and instantiate derived classes that didn't override certain members of the abstract base class that we want them to. So what we want to be able to do is specify that there are certain members of the base class that have to be implemented by the derived classes. To do this, we can use the abstract keyword that we learned about earlier to define specific base class members that must be implemented by subclasses. So here in our code in the abstract props funks folder let's open up our program and vehicle files. So let's take a look at the code for our vehicles class that we saw earlier. It's mostly the same with some slight changes. So I added a property for the number of wheels…
