I'm learning C++ and I'm just getting into virtual functions.
From what I've read (in the book and online), virtual functions are functions in the base class that you can override in derived classes.
But earlier in the book, when learning about basic inheritance, I was able to override base functions in derived classes without using
So what am I missing here? I know there is more to virtual functions, and it seems to be important so I want to be clear on what it is exactly. I just can't find a straightforward answer online.
