In Python- I am struggling with getting the functions to work properly with one another and having one inside the other has been causing my program to have issues. Julia has a problem. She goes grocery shopping on a weekly basis, and always seems to forget to buy items that she needs. You have suggested that she make a list before she goes, and have offered to write a program to help Julia produce her shopping list. The program should define and use the following functions to help perform the above tasks: addItem (some_list) The function addItem accepts one parameter, which is a list. This function prompts the user for an item to be added to the list. If the item is not already on the list, the item is added to the end of the list. Otherwise, a message is given indicating that the item is already on the list. removeItem(some_list) The function addItem accepts one parameter, which is a list. This function prompts the user for an item to be removed from the list. If the item on the list, it is removed from the list. Otherwise, a message is given indicating that the item was not on the list. printOut(some_list) The function printOut accepts one parameter, which is a list. This function prints out a header: GROCERY LIST followed by a list of all of the items in the list, one at a time THESE functions should be placed in a separate MODULE (another file). The main process will be in it's own file which import the function module in order to call these functions. The main part of the program will start by creating an empty list. The user will then be allowed to choose any of the following options UNTIL he/she wishes to exit. * ADD an item to the list The user will provide the item to be added. If the item is not on the list, it will be added, otherwise a message will be given that the item is already on the list. (You will call your addItem function to help here) * FIND an item on the list The user will provide an item and the program will report if the item is already on the list or not. * PRINT all items All items on the list are to be printed out, one per line (function printOut helps here) * REMOVE an item from the list The user will provide an item to be removed. If its there, it is removed, otherwise a message is given. (You will call your removeItem function to help here) Be sure your program is readable and well-commented. Test all options, remember some choices have two paths (eg. choosing ADD will either add an item or print a message). Place the functions in their own file (module) and import this file into the main..

I'm posting this again because the answer wasn't correct. **Please read this carefully and the prompt carefully** Hello All, I need help with Operations 4, 5, and 7. Make sure it's in C programming language. Operations needed: Operation 4 is Delete the entire list: When 4 is pressed, the program should delete each products information by removing all the nodes in the Linked List, including the head node that was created when you pressed 1. Operation 5 is Search a product: When 5 is pressed, the program should take the users keyboard input for the products name, search this product in the Linked List, and return the search result (Found, or Not Found). and Operation 7 is Purchase a product: When 7 is pressed, the program should take users keyboard input for the products name, and increase this products quantity by 1. I provided a code for what I have so far. Code #include #include #include // define a product struct typedef struct Product { char name[20]; int price; int quantity; struct Product* next; } Product; // declare global variables Product* head = NULL; // start of the linked list Product* tail = NULL; // end of the linked list // function prototypes void createList(); void insertProduct(); void removeProduct(); void deleteList(); void searchProduct(); void displayProduct(); void purchaseProduct(); void sellProduct(); void saveToFile(); int main() { char choice; do { printf("\n\nPlease choose an option:\n"); printf("1. Create a new list\n"); printf("2. Create a new product\n"); printf("3. Remove a product\n"); printf("4. Delete a list\n"); printf("5. Search a product\n"); printf("6. Display a product\n"); printf("7. Purchase a product\n"); printf("8. Sell a product\n"); printf("9. Save products to file\n"); printf("0.

CS 2336 PROJECT 3 – Linked Inventory Management Project Due: 11/04 by 11:59 PM KEY ITEMS: Key items are marked in red. Failure to include or complete key items will incur additional deductions as noted beside the item. Submission: • The file containing main must be named Main.java. (-5 points) • The project files must be in packages that start with LinkedInventoryManagement.* (-5 points) • All project deliverables are to be submitted in eLearning until further notice o Zip the contents of the src directory into a single zipped file o Make sure the zipped file has a .zip extension (not .tar, .rar, .7z, etc.) (-5 points) o Add your project’s presentation link in the comments section in eLearning • Programs must compile and run with Java SE 13. • Each student is responsible for developing unit test cases to ensure their program works as expected. • Type your name and netID in the comments at the top of all files submitted. (-5 points) Objectives: • Create a modular code solution with multi-packages • Use the Singleton pattern to create and manage the Scanner object • Create and manipulate a multi-directional LinkedList in Java • Use Java Generics to create generic classes and methods • Implement and use the Comparable interface Problem: A small electronics company has hired you to write an application to manage their inventory. The company requested a role-based access control (RBAC) to increase the security around using the new application. The company also requested that the application menu must be flexible enough to allow adding new menu items to the menu with minimal changes. This includes re-ordering the menu items and making changes to the description of a menu item without having to change the code. Security: The company has suggested to start the application by asking the user for a username and password to ensure that the user is authorized to access the application. There are two types of users at this company, managers and employees. If managers log on to the application, they will see all options on the menu list. If employees log on to the application, they will see a limited set of options on the menu list. User information is stored in Users.dat file, which may or may not exist at the start of the program. A super user “admin” with password “admin” has already been hardcoded in the program to allow for the initial setup and the creation of other users. The Users.dat file contains the FirstName, LastName, Username (case insensitive), HashedPassword and a flag to indicate whether a user is a manager or not. The file is comma separated and it is formatted as follows: Joe, Last, jlast, 58c536ed8facc2c2a293a18a48e3e120, true Sam,, sone, 2c2a293a18a48e3e12058c536ed8facc, false Jane, Best, jbest, 293a18a48e3e12052058c536ed8facc2c, false Application Menu: The menu of the application is dynamically loaded and displayed to the user only after the user successfully logs on. The menu items will be loaded from file “MenuList.dat”, which may o.

Toward an intuitive behaviour for GUI lists

JulienDelp

The document proposes a model for handling intuitive behavior in GUI lists when multiple user actions are combined. It defines a set of deltas (Add, Remove, Change, Filter, Sort, Select) that can be applied to lists and examines scenarios where multiple deltas are combined, such as sorting then selecting items or filtering and then removing an item. The objective is to make lists behave intuitively no matter the order of actions. Future work includes generalizing the model to handle tree structures and considering the visible portion of long lists.

This application is used to keep track of inventory information. A c.pdf

ambikacomputer4301

This application is used to keep track of inventory information. A company wants to allow users to input information about inventory items and then print a list of items in inventory that need to be re-ordered. There are three classes in this assignment (specific details further down) in addition to the application main class: The Inventory Class o This is the class that you wrote in Assignment 1. o You must make any necessary corrections to this class before you write this assignment. See your Assignment 1 evaluation. The InventoryList class o Models an Array or List of Inventory objects that are input by the user. The Assign2Controller class o Has an object of the InventoryList class to store and manage the information of items in the inventory. o This class must contain all event handling code needed to run the application (more details below). All classes must be part of the same package. 1. Inventory Class You wrote this class in Assignment 1. You must make any corrections to this class before you finish Assignment 2. 2. InventoryList Class The InventoryList class models a list of the inventory items entered by the user. For this assignment it will be used to contain Inventory objects as they are input by the user. The specs for the InventoryList class are shown in the diagram below: Class: InventoryList Data Members: - invList : ArrayList Method Members: + InventoryList() + add(inventory : Inventory) : void + get(index : int) : Inventory + length() : int The invList member is an Array or ArrayList of Inventory objects. You can instantiate the empty ArrayList in the same statement in which you declare it. The add() method accepts an Inventory object to add to the invList. There is nothing special going on here: simply add the object to invList. The get() method accepts an integer index and returns the Inventory object at that index, but only if the index is a valid index. If the index is invalid, the method should simply return a null object. The length() method returns the size of the invList (the # of elements that contain Inventory objects). You don't need a toString() at this time, but you could add one if you wanted to. The UI Controls, Layout, and Styling The Main UI Your program has the following UI elements (specific details about functionality are outlined later): A label heading with the text "Inventory Tracker". The label is bound to the top of the screen and remains centred, regardless of screen width. Label/TextField pairs to be used for data entry by the user. There is one pair of controls for each field input. The labels contain the String captions. The ADD button. This button has the hot-key "A" and is used to clear the input fields so that the user can easily type inputs for a new Inventory object. The SAVE button. This button has the hot-key "S" and is used to save the current input values as an Inventory object to the InventoryList. The inputs entered by the user are validated before the Inventory object is added to th.

Objectives: Use inheritance to create base and child classes Utilize multiple classes in the same program Perform standard input validation Implement a solution that uses polymorphism Problem: A small electronics company has hired you to write an application to manage their inventory. The company requested a role-based access control (RBAC) to increase the security around using the new application. The company also requested that the application menu must be flexible enough to allow adding new menu items to the menu with minimal changes. This includes re-ordering the menu items and making changes to the description of a menu item without having to change the code. Security: The company has suggested to start the application by prompting the user for a username and password to authenticate the user. There are two types of users at this company, managers and employees. If managers log on to the application, they will see all options on the menu list. If employees log on to the application, they will see a limited set of options on the menu list. User information is stored in Users.dat file, which may or may not exist at the start of the program. A super user “admin” with password “admin” has already been hardcoded in the program to allow for the initial setup and the creation of other users. The Users.dat file contains the FirstName, LastName, Username (case insensitive), HashedPassword and a flag to indicate whether a user is a manager or not. The file is comma separated and it is formatted as follows: Joe, Last, jlast, 58c536ed8facc2c2a293a18a48e3e120, true Sam, sone, samsone, 2c2a293a18a48e3e12058c536ed8facc, false Jane, Best, jbest, 293a18a48e3e12052058c536ed8facc2c, false Note: Ensure that the 'AddUser' function does not add duplicate values, and the 'ChangePassword' function does not change password if username/password is entered incorrectly. If adding a new user or changing the password is successful, return true, or else return false. Application Menu: The menu of the application is dynamically loaded and displayed to the user only after the user successfully logs on. The menu items will be loaded from file “MenuList.dat”, which may or may not exist at the start of the application. If the file doesn’t exist, the application should show at least an Exit menu item as default. The file will contain all menu items details, including the name of the command that will be executed when the menu item is selected. If a menu item is marked as restricted (Boolean flag), only managers can see that item. The file contains the following comma separated fields, Description, a Boolean flag to indicate if the option is restricted to managers only, and the name of the menu command that will be executed when the option is chosen. The order and option number of a menu item may change depending on how they are listed in the file. The Exit option will always be listed last and it will not be in the file. Below is a sample of how the MenuL.

It discusses the main components of a Visual Basic application, including forms, controls, properties, methods, and event procedures. It then describes various controls that can be used to build the user interface like text boxes, check boxes, option buttons, list boxes, combo boxes, and image boxes. For each control, it lists common properties, events, and methods.

Write a program (PYTHON) that allows the user to add, delete and org.pdf

prajeetjain

Write a program (PYTHON) that allows the user to add, delete and organize the items in a list. Your program will provide the following options: Append: adds an items, input by the user, at the end of the list. Delete: removes an item indicated by the user from the list. Move up: moves an item indicated by the user, to the previous position in the list. Move Down: moves an item indicated by the user to the next position in the list. Move Top: moves an item indicated by the user to the the first spot in the list. Move Bottom: moves an item indicated by the user to the last position in the list. Swap: swaps two items indicated by the user in the list. List all: display the items in the list; one item per line. Quit: allows the user to end the program. Your program shall show appropriate error messages when trying to move, swap, or delete items not found in the list. You program shall also properly handle invalid actions, like trying to move up the first item in the list, or trying to move down the last item in the list. In order to get you started, download the file list_maintainer_base.py which you can find at the bottom of this page. Here is a sample run. Let\'s assume we already added the following items (in this order): cake, cookies, ice cream. Adding \"donuts\" Listing all items here is the code for the list: def add_item(alist): print(\"[Add Item]\") # Read a string from the user # Add that string to the end of the list def show_menu(): print(\'\'\' List Maintainer 3000 Menu: [A]dd item to the list, [R]emove item from list, [U] move an item up, [D] move an item down, [T] move item to the top, [B] move item to the bottom. [L]ist all items, [Q]uit program, [S]wap two items \'\'\') def read_option(): option = input(\"Enter an option: \").upper() while option not in \"ARUDTBLSQ\": print(\"Error: Invalid option. \") option = input(\"Enter an option: \").upper() return option def main(): the_list = [] ##<--list to store user items show_menu() option = read_option() while option != \'Q\': if option == \'A\': add_item(the_list) elif option == \'R\': print(\"...remove item from list\") elif option == \'U\': print(\"...move item up\") elif option == \'D\': print(\"...move item down\") elif option == \'T\': print(\"...move item to the top\") elif option == \'B\': print(\"...move item to the bottom\") elif option == \'L\': print(\"...list all items\") elif option == \'S\': print(\"...swap two items\") else: print(\"Bye!\") show_menu() option = read_option() main() Solution Please find the solution program below: if any there is any, just need little tweaks only. Good luck def add_item(alist): print(\"[Add Item]\") item = input(\"Enter Item:\") for i in alist: alist.insert(i,item) #Adding Item to the List.syntax i = i + 1 # This keeps incrmenting the index value return alist def del_item(alist): element = input(\"Enter the item you want to delete:) try: if element in alist: number = alist.index(element) del alist[number] except: print(\"That Item is n.

In the pedigree below, persons with a hatched marking are afflicted by the same rare, autosomal recessive disease. The couple III-2 og III-3 are expecting a child and wishes to know the risk for their child to develop the dissease. a) What is the probability that IV-1 is affected by the disease based on the pedigree? A polymorph marker locus with two co dominant alleles A1 and A2 is found so close to the disease locus that no crossing over can be assumed to occur. The marker does not cause the disease but can be used as a tracker to follow the disease allele in different families. Genotypes for the marker locus are given for a number of persons in the pedigree including the IV-1 fetus. b) What are the genotypes of individuals I-1 and I-2 for the two loci? In your answer, include how the alleles of the disease locus (e.g. B and b) and the marker locus (A1 and A2) are positioned on the chromosomes e.g. -> (e.g. A1b/A2B, A1B/A2b, A2b/A2b, etc.). c) What is the probability that IV-1 will get the disease when the A-locus is taken into account? d) What is the probability that IV-1 will be a heterozygote (carrier) given the information above? e) Would the probability/answer to question c) change if the A-locus was linked less tightly to the disease locus, so that there was a few centiMorgan between them? How would it change and why? IVI II III ? IV A2A2.
