In this project, you should develop a library management system application using structuresand files. More specifically, your application should enable a user to read and write bookdetails to a file (books.txt). The file should store the following information for the books. Oneline per book and each field to be separated by tab.• Book ISBN• Book title• Author first name• Author surname• Year• Availability for loan [yes/no]The user of this application should have the following options in the form of a nice presentedmenu.Add a book: The user should add all the details of each book by answering a set of questions(book isbn? Book title? author? year?). The availability for loan is randomly generated by theprogram (y: yes, n:no). The book should be added at the end of the file.Search for a book: The user should be given three options here.▪ Search by the title: The user will input a keyword and the program willsearch for all the titles that contain this keyword and display all…
Octave assignment 1-Introduction to Octave Introduction This assignment is meant to be a gentle introduction to Octave, the free version of Matlab. It assumes that you have no prior coding experience. Objectives Download Octave and run it or use https://octave-online.net/ Learn the basics of the Octave GUI. • Learn how to create a short executable file called an m-file (.m extension) and run it. • Learn what a data type is. • Learn how to declare variables of different data types. • Learn how to create matrices. • Learn how to use several of Octave’s functions for creating objects with random numbers. Instructions 1.) Create a file call it with the form exercise_1_first name_last name. Include the underscores in your file name. At the top of the file add the comment "“My first Octave assignment. I'm so excited, I just can't hide it." 2.) Create the following variables a = 2.3; b = -87.3; A = [1,2; 4,5]; Create a matrix 2 × 2 B using the rand() function. Create two random complex…
You are writing an application for the 911 dispacher office for a city. You need a data structure that will allow you to store all the residents' phone numbers and addresses. The common operations performed on the set of objects are: lookup an address based on the calling phone number. The client wants the program to be as efficient as possible. Which of the following data structures should you use in your design? Question 43 options: Hash table Binary search tree Heap Sorted linked List
astfoodStats Assignment Description For this assignment, name your R file fastfoodStats.R For all questions you should load tidyverse, openintro, and lm.beta. You should not need to use any other libraries. suppressPackageStartupMessages(library(tidyverse)) suppressPackageStartupMessages(library(openintro)) suppressPackageStartupMessages(library(lm.beta)) The actual data set is called fastfood. Continue to use %>% for the pipe. CodeGrade does not support the new pipe. Round all float/dbl values to two decimal places. All statistics should be run with variables in the order I state E.g., "Run a regression predicting mileage from mpg, make, and type" would be: lm(mileage ~ mpg + make + type...) To access the fastfood data, run the following: fastfood <- openintro::fastfood Create a correlation matrix for the relations between calories, total_fat, sugar, and calcium for all items at Sonic, Subway, and Taco Bell, omitting missing values with na.omit(). Assign the…
It should be designed as a Desktop Application (with GUI) developed with Java programming language.Note that you are not designing a Web Application or a Mobile Application.Create a project named “FavoriteBooks” which keeps a list of the books that a user has read and liked.This list is stored in a text document (.txt) file and for each book it keeps the following data separated by acomma (,):Book id, Title, Category, First Author Name and Surname, Award Winner, Rating, Year, Number of Pages, andShort Description. Book id: The data type of “Book id” is integer and will be incremented automatically by 1 whenever anew book is added to the list. Title: The data type of “Title” is String. Category: The data type of “Category” is String. It shows the category of a Book such as Arts, Biography,History, Science Fiction, Cookbook, Literature, etc.. First Author Name and Surname: The data type of “Author Name and Surname” is String. Award Winner: The data type of “Award” is String. If the…
You develop a Python application for your company. A list named employees contains 200 employee names, the last five being company management. You need to slice the list to display all employees excluding management. Which two code segments should you use? Each correct answer presents a complete solution. (Choose two.) Group of answer choices employees [1:-5] employees [1:-4] employees [0:-5] employees [0:-4] employees [:-5]
Q.Create an interesting educational information chat box that asks the user to give an input question and then answers the question given by user with a suitable answer. You can make use of list for different questions and answers.Save two to three answers for a single question and then for random selection of elements from those answers use random choice(list) method from random module that returns a random element. Also for a user question that doesn't matches with the questions present in the chat box it should display statement like "oops i can't answer that" "sorry i am not intelligent enough" "could u please ask something else" using random method so that every time one of these statements appear **coding language python ***try using basic programming techniques in python without using arrays and pointers * * * copy paste the program itself and also the screenshot of program and output * * * use any type of data for questions such as name details of cities species etc depends on…
Write a program that will prompt the user for a username and validate that username is in the approvedUsers dictionary before prompting for the password. # approvedUsers = {"user1": "paswd", “user2":"paswd2", “user3": “paswd3", “user4":"paswd4"} # Hint: multiple function should be used
Step1-Study the scenario below and create a Java Program for Builders Warehouse, The program must consist of a class called Materials to handle the details of the materials. Step 2-The program should read the materials details from the material.txt file then use a LinkedList to store the material details. Step 3-Then finally the products stored in the LinkedList must be displayed like the sample code below: Step 4-There must be clear code and a screenshot of the code running.
code: public class PasswordGeneratorAndStorage {/*** Adds an application to the applications ArrayList. If index is -1, add application* to the end of applications.

Use C++ Programming language. The header file below defines a class for a simple hash table: hashMap.h Download hashMap.h Write a driver program to test the class with the following data: (520, "3100 Main St, Houston TX "); (37, "2200 Hayes Rd, Austin TX"); (226, "1775 West Airport St, San Antonio TX"); (273, "3322 Walnut Bend, Houston TX"); (491, "5778 Alabama, Waco TX"); (94, "3333 New St, Paris TX"); Make sure to test the find function for exiting and non-existing data 2. Modify the type of member key in class HashEntry from int to a string (this is useful is the key is e.g. the phone number or e-mail address). Use the string hash function discussed in class (see ppt notes) or search online for alternative functions that work on strings. 3. Modify the collision strategy of class HashMap to do separate chaining instead of linear probing. Be sure to modify the display function so that items in the bucket chains are also displayed in a pre-defined order…
