Write a paragraph to reflect on what you have learned in this assignment in terms of the difference between relational databases versus spreadsheets. Discuss ways in which a relational database could be useful for your work (if you have a job) or for your personal or professional projects (if you are a full-time student)

void main()
{
    Grade g1; //object for grade
    char h;

    cout << "enter character" ;
    cin>>h; //getting value
    g1.grade(h);
    g1.print();

   getch();
}

create an output file (named “output.txt”), and save the character to this output file. Last, close this output file

(C++) I'm getting a few errors that prevents the program from running what is causing this?

For this exercise, you will implement two programs that allow the user to enter grades in a gradebook. The first program will use one‐dimensional arrays, and the second program will use two‐dimensional arrays. The two programs function the same

Write an application that prints out the final grade of the students in a class and the average for the whole class. There are a total of 3 quizzes. You will need 4 arrays:

1. An array of type int to store all the ID's

2. An array of type double to store all scores for quiz 1

3. An array of type double to store all scores for quiz 2

4. An array of type double to store all scores for quiz 3

How to proceed:

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

2. Allocate 4 arrays that will store the data.

3. Use a FOR loop to retrieve and store all the data.

4. Use another FOR loop to  

a. Output the final score for each student.

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

5. Calculate and Output the average for the class.

Format all floating‐point numbers to 2 decimal places

Your program MUST receive user input as shown in the sample output.

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

Also, this is for java language.

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.

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.)

3. What are some issues that can arise when importing data from an outside

source into a DBMS? What are some tools or ways to resolve these issues?

4. Why do tables have to be related in Access for queries to work correctly?

5. What are the benefits and drawbacks for using a DBMS vs. a spreadsheet

to store data?

Describe and explain the advantages and disadvantages of network-based and host-based intrusion detection categories.

3. (5pts.) When should a Count controlled loop be used? C++

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]
