Chapter 22, Problem 4QY

using c++ create a linked list so that the linked list can read content from a binary file and write the list back to a binary file. The binary file to read should look something like this: 9 -3 5 2 6 8 it should have a list of integers to read into your linked list, NOT a list of commands like: L1.insertTail(5);

In Java programming  Write the code to print out an order for an individual customer. Your code must read the order header from a file, populate the object, and display the data from the object. Then you must read each line item from a file, populate the object, place the object in a linked list, and display the data by reading from the linked list after all the line items have been added.   Use the object names for Order and OrderDetail  OrderDetail orderdetail = new OrderDetail ( “order details” ); Assume you have opened two files and populated each object with the correct values Write the signature line for this method. Write the line of code to display the OrderID property from the order object. Be sure to include a textual description. Write the line of code to display all of the properties from the order detail object. Be sure to include a textual description of each property

Create a code for the bank transaction record using linked list.

Implement all the functions from the Question 2 and make a login and sign up module, all thedata will be stored in the files and as well as in the linked list, Program will have two modules1. login2. sign upSign Up:In this module the program will ask the user to enter username, password, address, city, phonenumber, gender and will store the data in the linked list. If the username already exists in thelinked list it will ask the user to change the username, all the data will also be stored in the textfile.Login: In this module the user will enter its username and password, the program will check if the dataexists in the linked list, if yes then show “Welcome to home screen”, if not then ask the user toenter the username and password again.Work Flow:1. The program will start and all the data from the files will be loaded in the linked list.2. The login and sign up screen will pop up3. Apply proper checks, if the file exists or not (Hint: you can use try catch to handle theexceptions)…

You can make this code connection functions between P2P machines: import threading import socket import pickle import time import struct import hashlib import os class FileManager(object): def __init__(self): self.files = {} self.download_path = "" def hash_data(self, data): hasher = hashlib.md5() hasher.update(data) return str(hasher.hexdigest()) def hashFile(self, filepath): hasher = hashlib.md5() try: with open(filepath, "rb") as afile: buf = afile.read() while len(buf) > 0: hasher.update(buf) buf = afile.read() return hasher.hexdigest() except: print("Couldn't find/hash file " + filepath) def refresh(self): for i in list(self.files): if self.files[i]["path"] is not None: if not os.path.exists(self.files[i]["path"]): print(…

Q4 Using the Linux Shell write a script that takes two files as arguments and determine if they are hard links of each other by comparing inode values. Test with two files with the name inode, a file against itself, two different files and a file against a symbolic link to itself.

If wrong answer this time will downvote it Create a class with a static main that tests the ability to resolve and print a Path: • Create an instance of a FileSystem class. • Resolve an instance of a Path interface from a directory path and filename. • Print the constructed Path with System.out.println() method. 2. Create a class with a static main that tests the ability to resolve and print a Path: • Create an array of Path class. • Instantiate instances of Path with absolute and relative paths. • Print the constructed elements of the array of Path class with System.out.println() method. 3. Create a class to test serialisation class that implements serializable, it should implement the following: • A static void method that serialises an object. • A static void method that deserializes an object. • A static main method that tests the two by moving an object from one to the other

The linked list is Select one: a. A link that points to another link b. a pointer that points to node structure c. Array of nodes structure d. array of pointers each one point to node structure
