Given the declarations (C++) struct ListNode {    float volume; ListNode* link; }; ListNode* headPtr; ListNode* currPtr; assume that headPtr and currPtr point to a linked list of many nodes. Write the statements that remove the second node.

In c++, how do I display the last node in a linked list?

struct insert_at_back_of_sll { // Function takes a constant Book as a parameter, inserts that book at the // back of a singly linked list, and returns nothing. void operator()(const Book& book) { /// TO-DO (3) /// // Write the lines of code to insert "book" at the back of "my_sll". Since // the SLL has no size() function and no tail pointer, you must walk the // list looking for the last node. // // HINT: Do not attempt to insert after "my_sll.end()". // ///// END-T0-DO (3) ||||// } std::forward_list& my_sll; };

JAVA CODE Learning Objectives: Detailed understanding of the linked list and its implementation. Practice with inorder sorting. Practice with use of Java exceptions. Practice use of generics.   You have been provided with java code for SomeList<T> class.  This code is for a general linked list implementation where the elements are not ordered.  For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back.  You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back.  You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list.  Your code to remove an object must include the exception NoSuchElementException.  Demonstrate your code by displaying the ordered linked list and…

C++ The List class represents a linked list of dynamically allocated elements. The list has only one member variable head which is a pointer that leads to the first element. See the following code for the destructor to List. ~ List () {      for (int i = 0; i <size (); i ++)       {             pop_back ();          } } What problems does the destructor have? Select one or more options: 1. There are no parameters for the destructor. 2. The return value from pop_back (if any) is nerver handled. 3. The destructor will create a stack overflow. 4. The destructor will create dangling pointers. 5.The destructor will create memory leaks. 6.The destructor will create undefined behavior (equivalent to zero pointer exception). 7.The condition must be: i <size () - 1 8. There is at least one problem with the destructor, but none of the above.

@6 The Reference-based Linked Lists: Select all of the following statements that are true.   options:   As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions.   According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node.   According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node.   In a double-ended singly linked list, the tail reference variable provides access to the entire list.   In a circular linked list, the last node references the first node.
