Assume that we have a node structure that contains a pointer field named next for linking to another node structure of the same kind and a chain of one or more nodes has been created with the head node pointed by the pointer variable named head. Let cur be a helper pointer variable that is used to point to a node structure. Which is the correct code snippet for making cur point to the last node in the chain. O None of these. cur = nullptr; while (cur->next != nullptr) { cur->next = cur; cur = head; while (cur->next != nullptr) { cur = cur->next; cur = head; while (cur != nullptr) { cur = cur->next; }

Write a function called findavg that takes a pointer to a struct student as inputand will return the average of the test scores in their list. Use the const keyword ifapplicable.   Any help would be appreciated!

please help

In C++,define a vector object and initialize it with 3 values and then define an iterator that points to elements of this object, then ask the user to enter 3 more values and then add them to the previous vector and then print all elements in the vector.

please answer

use replit please Thank you

Every data structure that we use in computer science has its weaknesses and strengthsHaving a full understanding of each will help make us better programmers!For this experiment, let's work with STL vectors and STL dequesFull requirements descriptions are found in the source code file Part 1Work with inserting elements at the front of a vector and a deque (30%) Part 2Work with inserting elements at the back of a vector and a deque (30%) Part 3Work with inserting elements in the middle, and removing elements from, a vector and a deque (40%) Please make sure to put your code specifically where it is asked for, and no where elseDo not modify any of the code you already see in the template file This C++ source code file is required to complete this problem

please answer

Please,help me by providing C++ programing solution. Do not use the LinkedList class or any classes that offers list functions. Implement a LinkList in C++. Pease,implement with an ItemType class and a NodeType structThe program should read a data file,and the data file has two lines of data as follow:100, 110, 120, 130, 140, 150, 160100, 130, 160The program will first add all of the numbers from the file,then display all of them,then delete.
