- Write a program in c++ and make sure it works, that reads a list of students (first names only) from a file. It is possible for the names to be in unsorted order in the file but they have to be placed in sorted order within the linked list.The program should use a doubly linked list.Each node in the doubly linked list should have the student’s name, a pointer to the next student, and a pointer to the previous student. Here is a sample visual. The head points to the beginning of the list. The tail points to the end of the list. When inserting consider all the following conditions:if(!head){ //no other nodes}else if (strcmp(data, head->name)<0){ //smaller than head}else if (strcmp(data, tail->name)>0){ //larger than tail}else{ //somewhere in the middle} When deleting a student consider all the following conditions:student may be at the head, the tail or in the middleBelow, you will find a sample of what the file looks like. Notice the names are in…Write a class that maintains the top 10 scores for a game application, implementthe add and remove functions. use a singlylinked list instead of an array. C++ C++ C++Write a program that implements a sorted list using dynamic allocated arrays. DataFile.txt contains the information of poker cards. C: clubs(lowest),D: diamonds, H: hearts, S:spades(highest) 2 (lowest), 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A No Joker cards Any C cards are lower than any D cards. DataFile Content(You can write the file specification into your program.): H4,C8,HJ,C9,D10,D5,DK,D2,S7,DJ,H3,H6,S10,HK,DQ,C2,CJ,C4,CQ,D8,C3,SA,S2,HQ,S8,C6,D9,S3,SQ ,C5,S4,H5,SJ,D3,H8,CK,S6,D7,S9,H2,CA,C7,H7,DA,D4,H9,D6,HA,H10,S5,C10 H4, D5, HK, D2 H4, HK, SK C9,C10 For examples, DJ means J of Diamonds;H7 means 7 of hearts. Your job Create a list by dynamic allocated array and set the size to 20 Read the first 20 cards in the first line of the file, the put them one by one into the list by implementing and using putItem(). The list must be kept sorted in ascending order. Then print out all the cards in the list in one line separating by commas. Then delete the cards indicated in the second…
- Write a program in C that performs the following tasks: Store the information about books in the library using a linked list structure. Each book should have the following information: book name, author name, ISBN, and publication year. Allow the user to add a new book to the linked list. Allow the user to delete a book from the linked list based on ISBN. Allow the user to search for a book in the linked list based on book name, author name, ISBN or publication year. Display the list of all books in the library. Note: The program should use the linked list implementation for storing the books and should not use any built-in library functions for linked lists.Write a program which will concatenate two single linked lists. The structure is defined below. Assume that head1 contains the starting address of the first list and head2 contains the starting address of the second list. You need to join them together so that all the students’ roll no and names of both the lists will be displayed together with the help of head1 pointer. struct link { int rollno; char name[20]; struct link *next; }; typedef struct link node; node *head1=NULL, *head2=NULL; //global declarationwrite a c++ program to sort doubly linked list by swapping there links not the data.please don't use pointer to pointer or double pointer method.
- In C++, you are going to write a program that implements a doubly linked list. The data must be read from the files and you can put the file names in your program. With a NEW solution for a like! Letters.txt contains 26 English Letters: Copy the following exactly as it is into own .txt file to test: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Sequence.txt contains a list of numbers. Copy the following exactly as is into another .txt file 3,-3,19,-19,18,1,-2,3,-18,17,1,-3,-13,14 You need to 1. Create a doubly linked list by reading the 26 letters from Letters.txt. 2. Sequence.txt file contains a sequence of relative letter positions. The initial position is at the beginning of the list which is ‘A’. The first number in the sequence is ‘3’. So the currentp osition will move forward for three steps. Then the first letter to output is ‘D’ and now the current position is at ‘D’ as well. The second number in the sequence is ‘-3’. Then the second letter to output is the third…You will write a program to process the lines in a text file using a linked list ADT and raw pointers. Node class You will create a class “Node” with the following private data attributes: line – line from a file (string) next - (pointer to a Node) Put your class definition in a header file and the implementation of the methods in a .cpp file. Follow the style they use in the book of having a "#include" for the implementation file at the bottom of the header file. You will have the following public methods: Accessors and mutators for each attribute Constructor that initializes the attributes to nulls (empty string and nullptr) LinkedList class You will create a class “LinkedList” with the following private data attributes: headPtr – raw pointer to the head of the list numItems – number of items in the list Put your class definition in a header file and the implementation of the methods in a .cpp file. Follow the style they use in the book of having a "#include" for the…Write a C++ program to construct a phone directory using linked list only (No Arrays), the program should have following functions.

Write the definition of a function that calculates and returns the sum of the numbers in the list.What would be a way in implementing the Josephus problem in C++ using a vector or a list? That takes in three parameters, one the number of knights for the knight parameter. The second parameter, "skip", is the number of knights to skip and to execute the next night. Then the third parameter "start", is the index of the knight to execute first.Implement a city database using ordered lists. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using: an array- based list implementation. By using JAVA.
