c++method default arg isn’t saved]vtable #Ashish

Ashish said he was asked the same question in multiple c++ interviews. The default param value is “declared” in base class and/or derived class and isn’t saved in the vtable. It’s basically resolved statically, at compile time.

If you use a pointer to Base to invoke the virtual method, then the Base default value applies unconditionally, even though the subclass method is chosen at run time, via the vtable.
