Create an Ordered Doubly Linked List in C++. Remember that an ordered Linked List is one where inserts automatically place a new node so that all the nodes retain a certain order. This list should be templated where items should be in "ascending" order (i.e., if it is a list of numbers, it should be of order of least to greatest).

This array will be passed to the BuildDataList function as a parameter which will in turn construct the list, allocating memory as required, and return a pointer to the…
If you need to announce a Linked List Node structure for recording two data member with Name, Save Money, and a link pointer for next node in C language. The logical view is shown as attached figure. The requirement of data member record is following: Name is spelled by Character with maximal length 16; Save_Money is a positive integer number. Please filled the announcement statements for the Node of Linked List. struct Node { } node_Member; Save_Money; *next;

Please explain Q# 1, Why did our implementation of a linked list use an empty node instead of null? Group of answer choices 1. To take advantage of a common protocol 2. To avoid possible null pointer exceptions 3. All of these 4. It helps in implementing several operations Q# The purpose of an Abstract Data Type is Group of answer choices 1. To allow for a structure to be mutable 2. To represent the structure as a whole, rather than a single node 3. To allow implementation details to be hidden from the user 4. All of the above
(a) Write the similarities and differences between lists, tuples, arrays anddictionaries. (2)(b) Think and write one real –time scenario each where list, tuple and dictionary canbe used. Give the reason why you think the scenario is suitable.
