Explain your answer. Explain why?   _____ Two classes that exist in the same program can have functions with the same name or variables with the same name. Explain your answer above. Explain why?   _____ When using inheritance, the derived objects are constructed first and the base class object at the top of the hierarchy is constructed last. True False   _____ Default constructors are inherited from the base class, thereby eliminating the need for derived classes to define their own default constructors.   _____The extraction operator>> and the insertion operator<< returns a istream and ostream reference respectively so that input and output operations can be chained.   _____ Once a constructor is used for an individual object, you cannot use a constructor with that object again.
