Question

I am trying to understand a point here in C++.
If class A has a non-virtual method, and class B, which extends A, overrides that method, can i create an instance of B and somehow use the method defined in B?
Is there a point to override a non-virtual method?

Answer 1

Is there a point to override a non-virtual method?

You are not actually overriding, but this is the behavior, i.e

B* b = new B();
A* a = new B();
b->method(); //Calls B's method
a->method(); // Calls A's method

So, the pointer/reference type determines the method called.

can i create an instance of B and somehow use the method defined in B?

Yes. The pointer/reference type has to be of type B. (see previous example).

If you don’t declare method to be virtual, you cannot override it, but you can hide it.
