In Python Initially, you will prompt the user for the names of two files: one will contain Customer information, and the other will contain Product information, as described below. Sample files are attached (below) to this project so you can download and review them. Some test cases may use other files, which you will not be able to see, so it is important that your program ask the user for the file names, and be able to open and read any file. The Customer Information file will be a csv file, with no header row, in which each line has the following fields, which are separated by commas. Customer_Number Customer_Name Customer_Balance Customer_Password For example, the sample file named customers.csv has several lines, and the first two are: 24155,"Carey, Drew Allison",838.41,Bo7&J 24426,"Butler, Geoffrey Barbara",722.93,Ep5& The Product Information file will be a csv file, with no header row, in which each line has the following fields, which are separated by commas:…
Run the program below, which creates “Dates” in the HW library. You will need to change the input statement to account for the format of the raw data. Add the following to this data step: Using the yrdif function to add a variable called “Agetoday”, which is the age today. Use proc print to list all the variables to the output window. Remember to format all dates for output purposes. data HW.dates; input Subj $ DOB ; datalines; 001 11Nov06 002 25May07 003 25Dec06 ; run; proc; run;
I have a python programming question Create a package called geometry. Inside that package create two modules: rectangle.py and triangle.py. Also create an empty file with name __init__.py in the geometry package.Inside rectangle.py define three functions:1. rectArea(): this function takes two parameters length and width of a rectangle, calculates and returns the area.2. rectCircumference(): this function takes two parameters length and width of a rectangle, calculates and returns the circumference.3. isSquare(): this function takes two parameters length and width of a rectangle and returns true if they are equal otherwise returns false.Inside triangle.py define two functions:1. triArea(): this function takes two parameters base and height of a triangle, calculates and returns the area.2. triCircumference(): this function takes three parameters, three sides of a triangle and returns the circumference.Create main.py in the same directory as the geometry package. Import your modules.…
please created a c++ code regarding this screenshot i add and also please add professional comments in it using the // command
I need this done in C++ please! This program implements the top-level menu option 'R' of the Airport Application and constitutes Part 2 of the Airport Application Project requirement. When the user selects 'R' in the airport application, she will be taken to the "page" that is displayed by this program. This program is meant to replace the flight status report program (Programming Assignment 3) that did not use arrays to store the flight status information. It also reads the information from the file token wise.
Please answer this question in Javascript using const readline = require('readline'); 1. Creating a file called conversionutils.js. In this file, code the following functions: a. centi_to_milli: Takes a value for centimeters and returns the value in millimeters. b. meter_to_centi: Takes a value for meters and returns the value in centimeters. c. kilo_to_meter: Takes a value for kilometers and returns the value in meters. d. inch_to_centi: Takes a value for inches and returns the value in centimeters. e. feet_to_centi: Takes a value for feet and returns the value in centimeters. f. yard_to_meter: Takes a value for yards and returns the value in meters. g. mile_to_meter: Takes a value for miles and returns the value in meters. h. mile_to_kilo: Takes a value for miles and returns the value in kilometers. Make sure to export your functions to make this a module. 2. Create a file called conversion.js. Start by importing your conversionutils module. When…

M Gmail O YouTube A Maps S Translate Create a function named "area" that allows the user to calculate the area of a Rectangle, a Disk or a Triangle, as shown in the following Python Shell screenshot. Write a main code that keeps calling the function upon user's approval. You need to upload your Python file. Write your own code, cheating will result in a zero grade. Choose 1: Rectangle, 2: Disk, 3: Triangle: 1 enter height: 4 enter width: 3 Area = 12 do you want to try again?

Assignment #6 Download the partially completed program Project06.py. Prompt the user to enter appropriate data in order to calculate the area of the shape. Display the area of the shape with output labelled. For example: A square with sides 5.0 has an area of 25.0. A triangle with base 8.0 and height 15.0 has an area of 60.0. The formulae for the area of the shapes are: circle-radius', square - side, rectangle -length*width, triangle-0.5 base* height The program should check for negative value inputs. If a negative value is inputted, a message like "Invalid input value. Program is terminated." import math print("Let's calculate the area of a shape! \n") shape input ("Make your choice (circle/square/rectangle/triangle): ").lower()
