Question

Say I have something like — this is just an example mind you.

class Car
{
   void accelerate();
   void stop();
}

class Person
{
   void drive(Car car);
}

class Toyota : public Car
{
   void accelerateUncontrollably();
}

class ToyotaDriver : public Person
{
   void drive(Car car)
   {
      // How to accelerateUncontrollably without dynamic cast?
   }
}

A couple things, Toyotas and ToyotaDriver go together, i.e. I can have a ToyotaFactory class which will return the driver and the car. So the pieces are interchangeable and used in different parts of the code but a Toyota and a ToyotaDriver go together.

Answer 1

My impression is that using a dynamic_cast is absolutely fine here. No need to avoid it.
