• Repeated inheritance multiple inheritance where
  there are multiple paths to an ancestor
• Types of repeated inheritance
• replicated inheritance separate copies
  (gp_list_node)
• shared inheritance single copy (person)

• Eiffel by default shared inheritance
• can get replicated inheritance of individual
  members by renaming them

• C by default replicated inheritance
• can get shared inheritance by labeling the
  inheritance as virtual

class professor public virtual person, public
gp_list_node ... class student public
virtual person, public gp_list_node ...
