C++ pointer multi-inheritance fun

by
  • does pa point to a valid A object?
  • does pb point to a valid B object?

Yes, the C* gets converted so that pa and pb point to the correct addresses.

  • does pa == pb ?

No, usually not. There can’t be an A object and a B object at the same address.

Furthermore, does

  • pc == (C*) pa ?
  • pc == (C*) pb ?

The cast converts the pointers back to the address of the C object, so both equalities are true.
