Picture of Equivalent Data

Here is a picture of this situation. Even though both objects have equivalent data inside of them, (strA == strB) is false.

== reports false because there are two different objects, each with a unique reference.

QUESTION 21:

itemA == itemB

and that

itemB == itemC

.

How many objects are there?
