Task Create Application Named Teacherhtml Allows Teacher Enter Name Test Scores Student Po Q43820376
Your task is to create an application named teacher.html thatallows a teacher to enter the name and the test scores for astudent at a point of a semester – the scores are as low as 0 andas high as 100. After each entry, the application should continueto prompt the user if they would like to enter another score – theuser must type Y or N. When the user indicates that they have nomore scores to enter for that particular student, the user shouldbe prompted if they would like to enter another student (Y or N)and continue on. Once the user is done entering students and theirscores, each student with their average score should be displayedin one alert box. Entering Student Names • Should not be empty • Ifit is empty, the user should continually be asked to enter untilcorrect • All of this logic should exist inside one functionEntering Student Scores • Should not be empty • Should be between 1– 100 inclusive • If invalid, the user should continually be askedto enter until correct • All of this logic should exist inside asecond function Entering Whether There is Another Score OR WhetherThere is Another Student • Should not be empty • Can only be Y or yor N or n • If invalid, the user should continually be asked toenter until correct. NOTE: The message should be specific as towhether or not the user should be entering another student oranother score. Watch the demo video for further clarification. •All of this logic should exist inside a third function CalculatingAverage • All of the logic that determines the average score shouldexist inside a fourth function. Storing Each student’s Name andAverage Score • Each student name must be stored inside an array •Each average score for each student must be stored inside adifferent array • For example, after all of the students and theirscores are entered, two arrays like the following should have beenbuilt dynamically (as in, you don’t manually type this in…thesearrays are built while the program runs): var students = [“Paul”,“Sarah”, “Chet”]; var scores = [99, 2, 88]; • In this example,Paul’s average score is 99, Sarah’s is 2, and Chet’s is 88. (Paulis element 0 in both arrays, Sarah is element 1, and Chet iselement 2). Displaying the Final Output • The output should looklike (names and scores may differ): Test Data – WATCH THIS DEMOVIDEO • The Test data that will be used to ensure the program worksis as follows Name Score Score Score Score Paul 100 98 95 100 Sarah4 8 Chet 88 34 100 o Paul’s average should be 98% o Sarah’s averageshould be 6% o Chet’s average should be 74% • I will also betesting that names and scores cannot be left blank • I will also betesting that scores are between 1 and 100 inclusive • I will alsobe testing that only Y or y or N or n are valid answers to whetheror not I would like to add another score or another student andthat the invalid message is specific to whether I was entering ascore or a student (Javascript)

Task Programming Assignment Write Python Program Implements Simple Vehicle Class Class Mod Q43831963
Your task in this programming assignment is to write a Pythonprogram that implements a simple
vehicle class. The class models a vehicle that has a year, amake, and a model (e.g., 2016 Dodge Ram,
2007 Honda Civic, etc). For a 2016 Dodge Ram, for example, theyear is 2016, the make is Dodge, and
the model is Ram. You will be provided a template that includescode (that you cannot change) in the
main part of the program to test the vehicle class:
# ***DO NOT MODIFY OR REMOVE ANYTHING BELOW THIS POINT!***
# the main part of the program
v1 = Vehicle(“Dodge”, “Ram”)
v2 = Vehicle(“Honda”, “Odyssey”)
print “v1={} {}”.format(v1.make, v1.model)
print “v2={} {}”.format(v2.make, v2.model)
v1.year = 2016
v2.year = 2016
print “v1={} {} {}”.format(v1.year, v1.make, v1.model)
print “v2={} {} {}”.format(v2.year, v2.make, v2.model)
v1.year = 1999
v2.model = “Civic”
v2.year = 2007
print “v1={} {} {}”.format(v1.year, v1.make, v1.model)
print “v2={} {} {}”.format(v2.year, v2.make, v2.model)
This sample code should provide some details of how to structureyour vehicle class. Here’s what the
output of this code with a correctly implemented vehicle classlooks like:
v1=Dodge Ram
v2=Honda Odyssey
v1=2016 Dodge Ram
v2=2016 Honda Odyssey
v1=2016 Dodge Ram
v2=2007 Honda Civic
To help clarify, here are some specifics and/or constraints:
(1) The constructor must take two parameters, make and model,and make proper use of mutators to
set these values;
(2) By default, a newly instantiated vehicle has a year of2000;
(3) Accessors and mutators (using the decorator method discussedin class) for each instance
variable (i.e., year, make, and model) must be included;
(4) A vehicle must have a year that is between 2000 and 2018inclusive (i.e., implement range
checking so that any other provided value is ignored);
(5) You must include a meaningful header, use good coding style,use meaningful variable names,
and comment your source code where appropriate;
(6) Your output should be exactly like the sample run shownabove; and
(7) You must submit your source code as a single .py file.

As example articles smartphones, notebooks and accessories shall be ordered (due to clarityin the UML class diagram below data types, parameters anddestructors are omitted.)
Subtask 9
To test write a main function placing somearticles as new objects on the heap into an electronic shoppingcart:
- define a shopping cart object of typeShoppingCart using the standard constructor.
- Send a message to this object that the articles get freeshipping starting from 500 EUR.
- Add to this shopping cart a new accessory article on heap withan amount of three powerbanks “YOOLOX 10k WirelessPowerbank Qi” with single net price 31.08 EUR being nooriginal accessory.
- Print the complete shopping cart (there are shippingcosts).
- Add to this shopping cart a new smart phone “SamsungGalaxy S10+ SM-G975F/DS Dual SIM” with net price 661.67EUR, 8GB main memory size and Android OS operating system
- Add to this shopping cart two new smart phones “AppleiPhone 11 Pro 256GB” with net price 1097.47 EUR, 4GB mainmemory size and iOS operating system.
- Add to this shopping cart a new notebook “ASUS ROGStrix Scar III G731” with net price 1586.55 EUR, 16GB mainmemory size, “512GB SSD + 1TB SSHD” asdrive and MS Windows operating system.
- Print again the complete shopping cart (now there are noshipping costs).
With the end offunction mainautomatically the complete shopping cart object gets deleted; yourprogram shall show the outputs of the destructor calls like in theexample given below.

Subtask 2 Subtask 1 Define an abstract base class for an offered article with name Article. This class shall have following members: Define a class with name Accessory derived from abstract class Article. This class shall have following members: . a private Boolean attribute with name original for an original accessory. a public constructor with three parameters for the article name, the net price and whether it is an original accessory with true as default parameter. The tax rate shall be automatically initialised by the default parameter of class constructor Article. a virtual public destructor producing an output “-Accessory0” at its call (see examples at the bottom). • a virtual public method with name print without parameters writing the article name and “(original accessory)”, if it is an original one (see examples at the bottom). a private string attribute with name model storing the article model name. two private real valued attributes with names netprice for the net price and taxRate storing the tax value in percent of the article. a public constructor with three parameters to initialise the attributes of an object; the tax rate shall be a default parameter with 19 %. a virtual public destructor producing an output “-Article()” at its call and the article model name (see examples below). a public method with name set.model assigning a string parameter to the model name attribute a public method with name set.netPrice assigning the double parameter to the net price attribute. a public method with name get model without parameters returning the model name as function value. a public method with name get.netPcise without parameters returning the net price as function value. a public method with name get.grossPrice without parameters returning the gross price (gross price = net price + tax) as function value. a pure virtual public method with name print without parameter or return value. .
