How is Virtual Inheritance Implemented?

Expertise: Intermediate
Language: C++

October 23, 1998

When multiple inheritance is used, it is sometimes necessary to use virtual inheritance. A good example for this is the standard iostream class hierarchy:

 
//Note: this is a simplified description of iostream classes

class  ostream: virtual public ios { /*..*/ }
class  istream: virtual public ios { /*..*/ }

class iostream : public istream, public ostream { /*..*/ } //a single ios inherited
