Complete those portions indicated inthe template.The program has defined a structure named Sale.The structure has the following fields:string itemNameint quantitydouble unitPriceThe main function call loadUserlnput which returns a pointer to the first Sale element in the dynamicallyallocated array of Sale elements and an integer for the number of Sale elements in the array.The main function then calls printData to show the sale items including the total of cach sale item andthe total of the entire list.Function printDataThis is the function you need to complete as well as two other helper functions.In the function body, print the report heading.Then iterate through the array received through the parameters and print the data according to therequired format. For the total of each item, call getltemTotal.At the end of the report, print the total of the entire sale items by calling getTotal.Test The ProgramUse the following input data:Milk5.85Whole Wheet Bread3.75Kapkin2.35Paper Towel32.95Soop11.95The output should look exactly as follows:SalesItenQtyUnitAntwilk5.855.85Whole Whect BreadNapkinPaper TowelSoop3.752.352,957.503.7.058.851.951.95Total31.20

Java Programming Assignment 6 – The Web Browser Web browsers are deceptively complex programs. The simple task of opening a web page carries a lot of steps: networking calls, protocol exchanges, rendering graphics, download and storage, JavaScript functionality, etc. It’s a lot to handle. The myriad number of tasks at hand provides a great example of different situations for collecting and managing information. Perfect for trying out the Java Collections Classes. Program requirements: • Create a new class, called “WebBrowser.” Inside it, place your main program. When run, your program will ask the user for commands. The following commands should be provided: o GOTO o DOWNLOAD o BACK o FORWARD o SHOW_DOWNLOADS o CLEAR_DOWNLOADS o SHOW_HISTORY o CLEAR_HISTORY o END • For the command above, should be any user-input String in the format of a typical web address. • Inside your WebBrowser main program, create the following: o A Stack of Strings called “backwards” o A Stack…

Scheduling a Class (Intermediate above) You are an administrator for the Kulliyyah and is assigned the task to schedule a set of classes for a given day. Unfortunately, there is only one lecture hall and therefore, two classes cannot run at the same time. This is usually an easy task, however, there are some criteria that you would have to consider. The criteria are as follows: · Each class has a duration class time. · Higher level courses has higher priority than other low level courses. · Some lecturers prefer to have morning classes instead of the afternoon classes because they come to the office much earlier than other lecturers so they should be scheduled earlier. Your job is to propose the best scheduling based on this criteria. To do this, you will write a C++ program that will first sort the classes by lecturer arrive time and then by course levels. Lecturers arriving early, can start first, but if they arrive at the same time, the higher level course will go…

Problem Statement: Develop an Inventory Management System (IMS) for a small retail business that allows the user to manage their product inventory. The system should enable the user to add, edit, update, and delete product information stored in a .csv file. The IMS should be console-based with a menu-driven interface. Requirements: 1. Classes and Objects: - Create a `Product` class with attributes such as `productID`, `productName`, `price`, `quantity`. - Implement a `InventoryManager` class that will handle operations like adding, editing, updating, and deleting products. - Use a `Main` class with the `main` method to run the program and display the menu. 2. File Operations: - Store product information in a .csv file named `inventory.csv`. - Implement methods in `InventoryManager` for reading and writing to the .csv file. 3. Menu-Driven Interface: - Implement a menu in the `Main` class that allows the user to select operations like Add, Edit, Update, Delete, and View Inventory. - Use…
