You are to write a program that will handle the inventory for "widgets" - non-perishable hardware items. For bookkeeping purposes, the management of the inventory will follow a LIFO structure. Customers will be charged based on 40% markup of the most recent shipment of widgets, so the price when the item was received will be recorded with the shipment. Customer orders will be filled in FIFO order. Shipments will be received (saved in the appropriate structure) and sold in the order requests are received. If there are not enough widgets in stock for a sale, the balance of the customer's order will be placed on backorder (stored in an appropriate structure), and filled when the next shipment comes in, at the price they would have been charged, not the new price. DO NOT WRITE ANY CODE. DO NOT TRY TO SOLVE THE PROBLEM. JUST ANSWER THE FOLLOWING QUESTIONS: 1. What information will need to be stored in the widget class? 2. What information will need to be stored in the customer class? 3. What is the best data structure to maintain the inventory for the widgets? 4. What methods will be used in the inventory maintenance? Use the appropriate methods for the data structure. 5. What is the best data structure to maintain the backorder list for customers? 6. What methods will be used in the backorder maintenance? Use the appropriate methods for the data structure? BONUS: What special cases do you think should be considered? How should they be handled?

Loop through the animalList created in a previous question and print the total time taken and total time given for each animal. Example output: Zirly the Zebra - Time taken for all behaviors: 890 minutes of 1000 Henry the Hawk - Time taken for all behaviors: 350 minues of 1000 Choose one of the following from the above choices (A, B, C or D within the code):// Assume the following variables exist: Behavior[] someBehaviors = // Omitted for brevity Animal zirly = Animal("Zirly the Zebra", 812.3, someBehaviors); Animal henry = Animal("Henry the Hawk", 35.5, someBehaviors); Animal[] animalList = new Animal[]{ zirly, henry }; // --------------------------- // A for(int i = animalList.length; i < animalList.length; i++) { Animal tempAnimal = animalList[i]; int timeTakenSum = 0; int timeGivenSum = 0; for(j = 0; j < tempAnimal.getBehaviorList().length; j++) { Behavior tempBehavior = tempAnimal.getBehaviorList()[j]; timeTakenSum +=...

You have been hired at an open-air mine. You are to write a program to control a digger. For your task, you have been given a `map' of all the underground resources in the mine. This map comes as a file. The file has n rows. Each row has n space-separated integers. Each integer is between zero and one hundred (inclusive). The file should be understood to represent a grid, n wide by n deep. Each square in the grid can contain valuable resources. The value of these resources can go from zero (no resources) to 100 (max resources). The grid maps the resources just below the surface, and down to the lowest diggable depths. The digger starts at the surface (so, just on top of the topmost row in the grid)—at any horizontal position between 1 and n. The digger cannot dig directly downwards, but it can dig diagonally in either direction, left-down, or right-down. In its first time-step, it will dig onto the first row of the grid. In its second time-step, it'll hit the second row, and so on....

The owner of a venue for events needs software to keep track of reservations. The venue can handle two events in a day, one scheduled for the afternoon and another scheduled for the evening. Each event consists of the type (wedding, bar mitzvah, etc.), the date of the event, and whether or not the event will be held in the evening. A programmer writes the code given on the handout. Rewrite the above code so that It has all of the correct access modifiers for good encapsulation. Your code obeys the principle of encapsulation that obliges you to put each method in the proper class. Your code uses NO getters and NO additional classes or methods. You are welcome to modify any existing methods (including signatures and bodies) and/or move them between the existing classes. Your code DOES NOT modify any of the constructors. Important notes: You DO NOT have to write a main method. You DO NOT have to write tests. You DO NOT have to write Javadocs. You DO NOT have to write interfaces to...

In c++ Create a new project named lab9_2. You will continue to use the Courses class, but this time you will create a vector of Courses. The file you will read from is below: 6CSS 2A 1111 35CSS 2A 2222 20CSS 1 3333 40CSS 1 4444 33CSS 3 5555 15CSS 44 6666 12 Read this information into a vector of Courses. Then, print out a summary of your vector. Here's a sample driver: #include <iostream>#include <string>#include <fstream>#include <vector>#include <cstdlib>#include "Course.h"using namespace std;int main(){vector<Course> myclass;string dep, c_num;int classes, sec, num_stus;ifstream fin("sample.txt");if (fin.fail()){cout << "File path is bad\n";exit(1);}fin >> classes;for (int i = 0; i < classes; i++){fin >> dep >> c_num >> sec >> num_stus;// Now how do you create a Course object// that contains the information you just read in// and add it to your myclass vector?}cout << "Here are the college courses: "...

Write a python application to simulate an Online Book Shop. Notes: Option 1 and Option 2 must display the list of books to the user. The Main function accounts for invalid options. Program displays error message for invalid user option, invalid ISBN number or any invalid title.The programmer can create the book title, price, and ISBN information for the books. Each item consists only one string of comma-separated data: book ISBN number, title, and price. A customer can purchase some books either by ISBN number and/or by title. If the user input an invalid number or book title, the program should display an error message. The user can stop shopping with "checkout" option , which triggers the checkout() function that computes the total cost of the books in the cart. A customer will be provided the following menu option while shopping at the book shop: Option 1. Purchase by ISBN: User can purchase a book by its ISBN number. ISBN stands for International Standard Book Number. This is a...

Instructor note: This lab is part of the assignment for this chapter. This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations: Drives input number of miles forward Drives input number of miles in reverse Honks the horn Reports car status The SimpleCar class is found in the file SimpleCar.java. Ex: If the input is: 100 4 the output is: beep beep Car has driven: 96 miles

Using C++ For each game played you will write the final results for the player and the computer. The data written should look like this: 19 21 18 23 21 16 You will have the player data first, a tab '\t', and then the computer result followed by a newline '\n' So, in the example above, in the first game, the player got 19 and the computer got 21. In the second game, the player got 18 and the computer got 23. After the player stops the program, you will close the writing file stream and open the input file stream of the newly created file. Read each line of numbers and calculate: The average result of the player for all the games played. The average result of the computer for all the games played. The total wins for the player and the computer. Then, declare who is the best 21 player! The output from above will look like this assuming the computer is named, "Ruby." Your game average was 19.3 Ruby's game average was 20.0 You won 2...

In C++, using STL algorithms, use the text file shoes.txt, where you want to sell a pair of shoes to a customer. The price must come from the text file, and can be used to get the total for any shoe the user may choose. CONSOLE cout << "what shoes do you want to buy"; cin >> heels; cout << " that will be " shoe_price "!"; The cout should return " That will be 20ドル ! shoes.txt items: heels 20ドル shoes 12ドル yeezys 289ドル jordans 150ドル

ObjectiveThe purpose of the project is to write a program to generate all association rules whose support is greaterthan a user-supplied minimum support and whose confidence is greater than a user supplied minimumconfidence. You need to implement all the steps of the Apriori algorithm.Your code should be in a file named my_rules(.py). Your program should take as a command line option (or setthem at the beginning of your code) five parameters in the following order: (i) minimum support, (ii) minimumconfidence, (iii) input file name, (iv) output name. The output name will be used to identify the output filesfrom each run. When minconf=-1, do not generate rules.Input file formatThe input file, small.txt, consists of a set of lines, each line containing two numbers. The first number is thetransaction ID, and the second number is the item ID. The lines in the file are ordered in increasing transactionID order. Note that a transaction will be derived by combining the item IDs of all the...

Please help me write a program code for this project*Game design*creating a game.*Project description*:1. The game should ask the number of participants, then generate a random number which is stored in memory. The program should ask player 1 to enter a number of his choice. Then subtract that number from the number that was randomly generated by the computer. If the result of the operation is <0, player 1 loses. If the result is >= 0, the program should ask the next player to choose a number. The same operation is now performed on the number entered by player 2 which is then subtracted from the remainder after the operation carried out by player 1 and if the result is <0, player 2 loses else, the program continues until we have a loser. *Note* The program should generate random numbers from 0 - 100 inclusive and the program is not supposed to display the result of the operation.
