Subject: Security Policy & Procedures

Describe what a Data Flow Diagram is and why it is useful for IT auditing. One paragraph should describe what a Data Flow Diagram is, and the second paragraph should describe why it is useful for IT auditing.

You will need to use only two arrays:  One array of type int to store all the ID's

 One two‐dimensional array of type double to store all the scores for all quizzes

Note: The two dimensional array can be represented also with the rows being the students and the columns being the quizzes.

How to proceed:

1. Declare the number of quizzes as a constant, outside the main method. (Recall that identifiers for constants are all in CAPITAL_LETTERS.)

2. Ask the user how many students are in the class, so you can set the length of all the arrays.

3. Allocate 2 arrays, one one‐dimensional and the other two‐dimensional, that will store the data.

4. Use two nested FOR loops to retrieve and store all the data.

5. Use another two nested FOR loops to  

a. Output the final score for each student.

b. Keep track of all scores to later compute the average for the class.

6. Calculate and Output the average for the class.

Format all floating‐point numbers to 2 decimal places.

Please leave comments on the program so i can give you a thumbs up :)!

also, this is for java language

Assembly Language Programming:

a)If eax = 0FFFFFFFFH, and edx = 0FFFFFFFFH, then the instruction

                             imul edx

will leave the value ______________________________ in the edx register.

b)If eax = 0D000000DH, and edx = 50000005H, then the instruction

                             idiv dl

will leave the value ______________________________ in the eax register.

c)If ax = 3BC4H, then the following instructions

                             cmp ah, al

jg   Label

will / will not cause a jump to Label.

d)If ax = 3BC4H, then the following instructions

                             cmp ah, al

ja   Label

will / will not cause a jump to Label.

f) The following instructions

                             mov eax, 0

mov ecx, 1100B

L1: inc eax

loop L1

will leave the value ______________________________ in the eax register.

Given a string str of even length, print out the first half.  

Methods to use: substring(), length()

Testing cases:

WooHoo => Woo

HelloThere   => Hello

abcdef => abc

ab   => a

0123456789   => 01234

kitten   => kit

(Note that the sample input test cases are shown before the “=>” and the expected output each test case is after the “=>”.

Your program should print out the expected output only, not the input.)

Please create a Python program that can convert a text string to an encrypted message and convert the encrypted message back to the original message.

1. Read a string message from your keyboard.
2. Print the input string.
3. Convert this message into an encrypted message by using a list element substitution.
4. Print your encrypted message.
5. Convert this encrypted message back to the original message by using a list element substitution.
6. Print your original message.

Important: please use a dictionary data type and append function.

Question 1:

Processing Compound Data: Binary Trees

A binary tree is a tuple with the following recursive structure  

("btree", [val, left_tree, right_tree])

where first part of the tuple is a string "btree" and second part of the tuple is a list in which val is the value at the root and left_tree and right_tree are the binary trees for the left and right children or

("btree",[]) for the empty tree.  

(A)

Implement a binary tree ADT.

Type Name Description

Create the following tree in python. Use this tree to test the above functions of the tree ADT.

(B)

Implement the functions preorder,inorder and postorder.

Function preorder takes a tree as an argument and returns a list with the root value being the first element in the list followed by the elements of the left tree and then right tree. Function inorder takes a tree as an argument and returns a list with the elements of the left tree, followed by the root value and then right tree.

Function postorder takes a tree as an argument and returns a list with the elements of the left tree, followed by the elements of the right tree and then root value.

For example

preorder(t1) => [7, 5, 11, 9]

inorder(t1) => [5, 7, 9, 11]

postorder(t1) =>[5, 9, 11, 7]

Exercise 1

(a) Use javascript modify the code below, so that in addition to outputting the selection to the web page, the selection is also placed in the browser’s local storage. Use ‘select’ as the local-storage key. The value will be the name of the category that was selected or the empty string is no selection was made.

(d) Add a button called ‘retrieve’. When it is clicked the local storage is read and the prior selection is shown on the web page.


Exercise 2

(a) Extend the code from Exercise 1. When the user clicks the retrieve button the radio buttons or tick boxes are also updated to show the prior selection. Confirm your code is working by making a selection, then exiting the browser, then restarting the browser at the same page and then clicking the retrieve button.

(b) Extend your web page so that the last 10 filter selections are stored. The user is able to see these prior filter selections (perhaps by clicking a button) and then choose one selecting it, making that the current selection.

Chapter 6: Use a list to store the players

In Python, Update the program so that it allows you to store the players for the starting lineup. This

should include the player’s name, position, at bats, and hits. In addition, the program

should calculate the player’s batting average from at bats and hits.

its java language.

1. Create a class called Car. A Car has instance variables, constructor parameters, setters, and getters for “year manufactured” and “make” and “model” (e.g. 2016 Honda Civic) 2. Create a class called CarLot which has an array of 5 Car references. There are two constructors: (a) One constructor takes no parameters and simply populates the array with these cars: cars[0] = new Car(2016, “honda”, “civic”); cars[2] = new Car(2017, “Lamborghini”, “aventador”); cars[3] = new Car(2000, null, “caravan”); cars[4] = new Car(2010, “dodge”, null); (b) The other constructor takes one parameter: a Car, and puts into the array as the first (and only) element. 3. Create a method public void addCar(Car car) which adds the new Car to the first empty element in the array; if there is no empty element just System.out.println(“no room”) instead. 4. Create a method public Car getCar(int index) which returns a reference to the car at the specified array index; if the index is not valid (i.e. not 0 to 4) return null instead. 5. Create a method public Car getOldestCar() which returns a reference to the oldest car in the array. Use your Car class from the previous question. 2. Create a class called UsedCarLot which has an ArrayList of Car references. 3. The constructor takes parameter: the name of the UsedCarLot (e.g. “Jason’s Used Cars”)…store this in the instance variable String CarLotName and has an accessor too: public String getName(). Also the constructor does this: It simply populates the ArrayList with these cars: cars.add(new Car(2016, “honda”, “civic”)); cars.add(new Car(2017, “Lamborghini”, “aventador”)); cars.add(new Car(2000, null, “caravan”)); cars.add(new Car(2010, “dodge”, null)); 4. Create a method public void addCar(Car car) which adds the Car parameter to the ArrayList. 5. Create a method public void removeCarsBetween(int firstYear, int lastYear) which removes all Cars from the list which were manufactured between firstYear and lastYear (inclusive). Use an iterator. 6. Create a method public Car[] getCarsMadeBy(String maker) which returns an array of Car references…all of the Cars which are made by the parameter maker.
