Assignment #2 Instructions: Through this programming assignment, the students will learn to do the following: Learn to work with command line options and arguments Gain more experience with Makefiles Gain more experience with Unix Learn to use some of the available math funtions available with C Usage: mortgagepmt [-s] -r rate [-d downpayment] price In this assignment, you are asked to perform the mortgage payment calculation. All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate…
Assignment Name JavaScript Concepts III Assignment Filename lastname-circleArea.html (replace lastname with your last name). area.js Assignment Description This assignment demonstrates the following concepts: JavaScript Functions Assignment Instructions Write a JavaScript program that calculates the area of a circle: Write a function that calculates the area of a circle given the radius. Formula: Math.PI * (radius * radius) Your program code should contain appropriately named variables. Use documentation to identify various components of your program. Call the function once and pass a radius value of 10.75 to it. Use the starter files and complete the logic to satisfy the instructions. To access the files, download and save the circleArea.zip folder attached to this assignment. Then unzip the compressed folder to reveal the included files: circleArea.html and area.js. Be sure that the two files are in the same folder. Then write your code in the area.js…
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…

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…

Make Album in c++ You are going to develop a new class named Album. This class will has (at a minimum) teh following attributes and features: Attributes: Album Title Artist Name Array of song names (Track Listing) Array of track lengths (decide on a unit) At most there can be 20 songs on an album. Behaviors: Default and at least one argumented constructor Appropriate getters for attributes bool addTrack(string name, type duration) - adds track to album. You decide type on duration. Make sure you document what dis is. getAlbumLength() - method dat returns total length of album matching watever units / type you decide. getAlbumLength_string() - method dat returns total length of album in mm:ss format string. I would suggest using you're other getLength function here. string shuffleAlbum(int n) - method dat returns a formatted string made up of n random tracks from teh album. The string will be in the format [1] track_name (mm:ss), [2] track_name (mm:ss)... Well formatted print()…
