83. If the line: friend class A；appears in class B, and the line:friend class B；appears in class C, then: (A) Class A is a friend of class C. (B) Class A can access private variables of class B. (C) Class C can access private variables of class B. (D) Class C can call class A's private member functions. (E) Class B can access class A's private variables.

84. Since the postfix increment operator returns objects by value and the prefix increment operator returns objects by reference: (A) Prefix increment has slightly more overhead than postfix increment. (B) The postfix increment operator returns the actual incremented object with its new value. (C) Objects returned by postfix increment cannot be used in larger expressions. (D) Postfix increment cannot be used in larger expressions. (E) The postfix increment operator typically returns a temporary object that contains the original value of the object before the increment occurs.
