C++ Multiple Choice question please help

Why may a tree class have two versions of the insert member function? A. One is public, the other is private to hide private pointer information B. One is to use with a const pointer, the other with a regular pointer C. One returns the forward link, the other returns the backward link D. One returns the data, the other returns a pointer to the next node You are given pointers to first and last nodes of a singly linked list, which of the following operations are dependent on the length of the linked list? A. Delete the first node B. Delete the last node of the list C. Insert a new node as the first node D. Add a new node at the end of the list What are the "Big Three" in C++? A. Setters, getters, and constructor B. Setters, destructor, and constructor C. Copy constructor, constructor, and destructor D. Destructor, copy constructor, and overloaded copy assignment operator I have implemented the queue with a linked list, keeping track of a front node and a rear node with two reference variables. Which of these reference variables will change during an insertion into a NONEMPTY queue? A. Neither changes B. Only front changes. C. Only rear changes. D. Both change.

Explanation / Answer

Answer in bold.

25. Why may a tree class have two version of the insert member function.

A. One is public, the other is private to hide private pointer infromation.

26.

You are given pointers to first and last nodes of a singly linked list, whcih of the following operations are dependent on the length of the linked list.

B. Delete the last node of the list.

All others can be done in constnant time by pointer manipulation for first and last.

27. What are the "Big Three" in C++?

D. destructor, copy constructor and overloaded copy assignment operator

28. C. Only rear changes.
