WRITE 2 C FILE In this assignment you are required to follow the Unix domain server and client example done in the classroom. After this point, you need to setup the server in a way that it will process the data sent by the client and send back the processed data. You must read at least two set of data, and send back at least a piece of information. For instance, client might send two numbers and the server will send the summation back. This is only an example, please do something a little more complicated. I do not want to see same operation over and over again in the assignments. You can use scanf and printf with dup2 to obtain numbers. Alternatively, you could read the text and use sscanf and sprintf. You could also perform text based operations. It is up to you. You must perform all error checks.

please code pythonWe’ve already looked at several examples of API integration from a Python perspective and this week we’re going to write a program that uses an open API to obtain data for the end user. Create a program which uses the Request library to make a GET request of the following API: Chuck Norris Jokes. The program will receive a JSON response which includes various pieces of data. You should parse the JSON data to obtain the “value” key. The data associated with the value key should be displayed for the user (i.e., the joke). Your program should allow the user to request a Chuck Norris joke as many times as they would like. You should make sure that your program does error checking at this point. If you ask the user to enter “Y” and they enter y, is that ok? Does it fail? If it fails, display a message for the user. There are other ways to handle this. Think about included string functions you might be able to call. Your program must include a header as in previous weeks.…

Write a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet... File name: file_path2 Lorem ipsum dolor sit amet... ... # Put your code here import os   #module used to interact with operating system def displayFiles(pathname):  #recursive function that takes a pathname as argument   if (os.path.isdir(pathname)):  #checks if specified path (argument) is an existing directory       #for item in os.listdir(pathname):        for content in os.listdir(pathname):  #gets the list of all files and directories in the directory and…

Computer Science Write the code for a book managing system that will record books in a SQLite database in Android Studio using Java. The user need to register on the app by entering name, age, address, reading interest (e.g. fiction/nonfiction). The user will be provided with a user name/email ID, which will be used to maintain the record of each unique user. The app should ask a user to log in with a user name and password. Once the user is logged in, the app should display three options “Add a book, update a Book and Borrow a Book.   If a user chooses add a book option, new activity should open asking for book details (title, author, publisher and publication year). If a user chooses update a book option, new activity should open showing a particular book details and should give the option to update the book’s information including status. The book status needs to be updated if the book is borrowed by others.   If the user selects Borrow a Book option the app should ask the user to…

Project in Java programming language : Choose an enterprise and do a business description of it. 1-2 pages. Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.

GDB and Getopt Class Activity activity [-r] -b bval value Required Modify the activity program from last week with the usage shown. The value for bval is required to be an integer as is the value at the end. In addition, there should only be one value. Since everything on the command line is read in as a string, these now need to be converted to numbers. You can use the function atoi() to do that conversion. You can do the conversion in the switch or you can do it at the end of the program. The number coming in as bval and the value should be added together to get a total. That should be the only value printed out at the end. Total = x should be the only output from the program upon success. Remove all the other print statements after testing is complete. Take a screenshot of the output to paste into a Word document and submit. Practice Compile the program with the -g option to load the symbol table. Run the program using gdb and use watch on the result so the program stops when the…

Mutual Exclusion: Select all of the following statements that are true. The Peterson Algorithm does not rely on the mechanism of busy waiting. The Peterson Algorithm is a purely software-based solution to the mutual exclusion problem. The only way to guarantee the atomicity of operations is to disable interrupts. Mutex Locks are an API offered by operating systems to protect critical sections. In order to enter a critical section protected by Mutex Locks, the release() operation must be executed first. The test_and_set instruction is atomic.
