Question
In C++

Transcribed Image Text:Suppose a problem design requires storing a collection of objects. Suppose further
that the objects will have varying behavior, but they will be related through
inheritance. The base class for all the objects has declared some virtual functions and
the behavior of the derived classes varies when that function is invoked. Which of
the following statements are true?
I.If the objects are managed using for example, an array, the array should store
pointers to the objects, not the objects themselves
II.When the objects are passed as parameters to other functions, they should be
passed by reference
III.Using pointers to the objects as a way to manipulate them will enable polymorphic
behavior
