How does virtual inheritance solve the “diamond” (multiple inheritance) ambiguity?
...pe D would have 2 vtable pointers (you can see them in the first diagram), one for B and one for C who virtually inherit A. D's object size is increased because it stores 2 pointers now; however there is only one A now.
