Answer:
I think that they should ban ads for all four products. These products, e-cigarettes, abortion clinics, ice cream, and sugared soft drinks, are all discreet adult products that should not be advertised because of their health hazards. Since the "large online company provides a widely used search engine, social network, and/or news service, which are mainly patronized by younger people, such ads that promote products injurious to individual health should be banned. Those who really need or want these products know where they could get them. Therefore, the products should not be made easily accessible to all people. Nor, should ads promote their patronage among the general population.
Explanation:
Advertisements create lasting and powerful images which glamourize some products, thereby causing the general population, especially children, to want to consume them without any discrimination of their health implications. If online banning is then contemplated, there should not be any distinguishing among the four products: e-cigarettes, abortion clinics, ice cream, and sugared soft drinks.
Write a program in C# : Pig Latin is a nonsense language. To create a word in pig Latin, you remove the first letter and then add the first letter and "ay" at the end of the word. For example, "dog" becomes "ogday" and "cat" becomes "atcay". Write a GUI program named PigLatinGUI that allows the user to enter a word and displays the pig Latin version.
Answer:
The csharp program is as follows.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
string word = textBox1.Text;
string ch = word.Substring(0, 1);
string str = word.Substring(1, word.Length-1);
string s = str.Insert(str.Length, ch);
textBox2.Text = s.Insert(s.Length, "ay");
}
private void button3_Click(object sender, EventArgs e)
{
Close();
}
private void button2_Click(object sender, EventArgs e)
{
textBox1.Text = "";
textBox2.Text = "";
}
}
}
Explanation:
1. A string variable to hold the user input is declared and initialized accordingly. The user inputted string is taken from textbox1.
string word = textBox1.Text;
2. A string variable to hold the first character of the user inputted string is declared and initialized.
string ch = word.Substring(0, 1);
3. A string variable to hold the user inputted string without the first character is declared and initialized accordingly.
string str = word.Substring(1, word.Length-1);
4. A string variable to hold the substring from step 3 along with the inserted characters at the end, is declared and initialized accordingly.
string s = str.Insert(str.Length, ch);
5. The final string is assigned to the textbox 2, which is the PigLatin conversion of the user inputted string.
textBox2.Text = s.Insert(s.Length, "ay");
6. All the above take place when the user clicks Convert to PigLatin button.
7. Two additional buttons, clear and exit are also included in the form.
8. When the user clicks clear button, both the textboxes are initialized to empty string thus clearing both the textboxes.
textBox1.Text = "";
textBox2.Text = "";
9. When the user clicks the exit button, the application closes using the Close() method.
10. The program is done in Visual Studio.
11. The output of the program is attached.
12. The program can be tested for any type of string and any length of the string.

Answer:
Raid
Explanation:
Part 1: For this assignment, call it assign0 Implement the following library and driver program under assign0: Your library will be consisting of myio.h and myio.c. The function prototypes as well as more explanations are listed in myio.h. Please download it and accordingly implement the exported functions in myio.c. Basically, you are asked to develop a simple I/O library which exports a few functions to simplify the reading of an integer, a double, and more importantly a string (whole line). In contrast to standard I/O functions that can read strings (e.g., scanf with "%s", fgets) into a given static size buffer, your function should read the given input line of characters terminated by a newline character into a dynamically allocated and resized buffer based on the length of the given input line. Also your functions should check for possible errors (e.g., not an integer, not a double, illigal input, no memory etc.) and appropriately handle them. Then write a driver program driver.c that can simply use the functions from myio library. Specifically, your driver program should get four command-line arguments: x y z output_filename. It then prompts/reads x many integers, y many doubles, and z many lines, and prints them into a file called output_filename.txt. Possible errors should be printed on stderr.

return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
/* Your solution goes here */
System.out.println("Testing completed");
return;
}
}

public class UnitTesting {
// Function returns origNum cubed
public static int cubeNum(int origNum) {
return origNum * origNum * origNum;
}
public static void main (String [] args) {
System.out.println("Testing started");
System.out.println("2, expecting 8, got: " + cubeNum(2));
System.out.println("3, expecting 27, got: " + cubeNum(3));
System.out.println("-1, expecting -1, got: " + cubeNum(-1));
System.out.println("Testing completed");
return;
}
}
Explanation:
Added statements are highlighted.
Since the cubeNum function calculates the cube of the given number and we are asked to write two statements to test inputs 3 and -1, pass the parameters 3 and -1 to the function called cubeNum and print the results using print statements
The degree of a point in a triangulation is the number of edges incident to it. Give an example of a set of n points in the plane such that, no matter how the set is triangulated, there is always a point whose degree is n−1.
Answer:
squarepentagonExplanation:
The vertices of a square is one such set of points. Either diagonal will bring the degree of the points involved to 3 = 4-1.
The vertices of a regular pentagon is another such set of points. After joining the points in a convex hull, any interior connection will create a triangle and a quadrilateral. The diagonal of the quadrilateral will bring the degree of at least one of the points to 4 = 5-1.

A loop that prints the words in uppercase letters is written below with the help of Python.
What is a function?Simply said, a function is a "chunk" of code that you may reuse repeatedly so instead of having to write it out several times. Software developers can divide an issue into smaller, more manageable parts, which can each carry out a specific task, using functions.
A function, according to a technical definition, is a relationship between an amount of parameters and a set of potential outputs, where every other input is connected to precisely one output.
All the functions are to be written in uppercase:
w = ["Algorithm", "Logic", "Filter", "Software", "Network", "Parameters", "Analyze", "Algorithm", "Functionality", "Viruses"]

Write a C++ program to find if a given array of integers is sorted in a descending order. The program should print "SORTED" if the array is sorted in a descending order and "UNSORTED" otherwise. Keep in mind that the program should print "SORTED" or "UNSORTED" only once.
Answer:
The cpp program for the given scenario is as follows.
#include <iostream>
#include <iterator>
using namespace std;
int main()
{
//boolean variable declared and initialized
bool sorted=true;
//integer array declared and initialized
int arr[] = {1, 2, 3, 4, 5};
//integer variables declared and initialized to length of the array, arr
int len = std::end(arr) - std::begin(arr);
//array tested for being sorted
for(int idx=0; idx<len-1; idx++)
{
if(arr[idx] < arr[idx+1])
{
sorted=false;
break;
}
}
//message displayed
if(sorted == false)
cout<< "UNSORTED" <<endl;
else
cout<< "UNSORTED" <<endl;
return 0;
}
OUTPUT
UNSORTED
Explanation:
1. An integer array, arr, is declared and initialized as shown.
int arr[] = {1, 2, 3, 4, 5};
2. An integer variable, len, is declared and initialized to the size of the array created above.
int len = std::end(arr) - std::begin(arr);
3. A Boolean variable, sorted, is declared and initialized to true.
bool sorted=true;
4. All the variables and array are declared inside main().
5. Inside for loop, the array, arr, is tested for being sorted or unsorted. The for loop executes over an integer variable, idx, which ranges from 0 till the length of the array, arr.
6. The array is assumed to be sorted if all the elements of the array are in descending order.
7. If the elements of the array are in ascending order, the Boolean variable, sorted, is assigned the value false and for loop is exited using break keyword. The testing is done using if statement.
8. Based on the value of the Boolean variable, sorted, a message is displayed to the user.
9. The program can be tested for any size of the array and for any order of the elements, ascending or descending. The program can also be tested for array of other numeric data type including float and double.
10. All the code is written inside the main().
11. The length of the array is found using begin() and end() methods as shown previously. For this, the iterator header file is included in the program.

An aside element is defined as a section of a page that has content that is tangentially related to the content around the element. In other words, the aside element represents content that is indirectly related to the main content of the page. Therefore, we can say that the correct answer to this question is B. Aside element.
A(n) ________ is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
Answer:
Network Operating System (NOS)
Explanation:
A network operating system (NOS) is an operating system that makes different computer devices connect to a common network in order to communicate and share resources with each other using a server. A network operating system can be used by printers, computers, file sever among others, and they are connected together using a local area network. This local area network which they are connected to works as the server.
The NOS also acts as a network security because it could be used as an access control or even user authentication.
There are two types of NOS
1) Peer to peer network operating system.
2) Client/server network operating system
A network operating system (NOS) is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
In this assignment, you will develop a C++ program and a flowchart that calculates a cost to replace all tablets and desktop computers in a business. Customers paying cash get a ten percent discount applied to the total cost of the computers (desktop and tablets). Customers financing the purchase incur a fifteen percent finance charge based on the total cost of the computers (desktop and tablets). Tablets costs $320.00 each and desktops costs $800.00 each. The tax is 75% (.075).
Requirements:
⦁ Use the following variables of the appropriate type: name of company selling the computers, the cost per each type of computer, number of computers to be purchased, discount if paying cash, sales tax rate. Tablets =$320 each and desktop computers = $800.00 each. Sales Tax Rate = .075, Discount Percent = .10, and Finance Charge = .15.
⦁ Variable names must be descriptive.
⦁ Use additional variables to hold subtotals and totals.
⦁ For customers paying cash, the discount should be subtracted from the total computer cost.
⦁ For customers financing the purchase, the finance charge should be added to the total computer cost.
⦁ The body of your program must use variables only; there should not be any "hard coded" values in the output statements. An example of hardcoding is
***Cost of tablets = 4 * 320****.
⦁ Use cout to output the values of the variables to the console. Your cout statement MUST use the variables to display the values
⦁ Display the cost of the computers, tax and average cost per computer. The average cost will be the total cost divided by the number of computers purchased. Display the discount if the customer decides to pay cash or the finance charge if the customer finances the purchase.
⦁ Output must be labelled and easy to read as shown in the sample output below.
⦁ Program must be documented with the following:
⦁ // Name
⦁ // Date
⦁ // Program Name
⦁ // Description
⦁ Develop a flowchart
Hints:
Total cost of computers = cost per tablet * number of tablets purchased + cost per desktop * number of desktops purchased
Calculate the cost if paying cash or financing
Calculate the tax
Average cost per computer = Total computer cost divided by the number of computers purchased

Explanation:
Program Description:
In the above-given program, inside the main method, a variable is declared that are investment_amount, interest_rate, future_investment_value, and years, in which only year variable is an integer type and other variables are double types.In the next step, a scanner class object that is "obx" is created, which is used to input value from the user end, in the next line we apply the formula to calculate the future_investment_value.At the last step, we all the input and a calculated valueA small publishing company that you work for would like to develop a database that keeps track of the contracts that authors and publishers sign before starting a book. What fields do you anticipate needing for this database
Answer:
The database can include the fields related to the Author such as name and address, related to Publisher such as publisher's name and address, related to book such as title and ISBN of the book and related to contract such as payment schedule, contract start and end.
Explanation:
The following fields can be needed for this database:
Author First_NameAuthor's Last_NameAuthors_addressPublisher_namePublisher_addressBook_titleBook ISBNcontract date : this can be start_date (for starting of contract) and end_date ( when the contract ends) payment_made: for payment schedule.For this project, you have to write 3 functions. C++
1. remove_adjacent_digits. This takes in 2 arguments, a std::vector, and a std::vector of the same size. You need to return a std::vector, where each of the strings no longer has any digits that are equal to, one more, or one less, than the corresponding integer in the 2nd vector.
2. sort_by_internal_numbers. This takes in a single argument, a std::vector, and you need to return a std::vector, which is sorted as if only the digits of each string is used to make a number.
3. sort_by_length_2nd_last_digit. This takes in a std::vector>. It returns a vector of the same type as the input, which is sorted, first by the length of the string in the pair, and if they are the same length, then the second last digit of the int.
See the test cases for examples of each of the above functions.
You need to submit a single file called main.cpp that contains all these functions. You can (and should) write additional functions as well. There is no need for a main function.
No loops (for, while, etc) are allowed. You must use only STL algorithms for this project.

Transaction is an action or series of actions the execution of which should lead to a consistent database state from another consistent database state. Discuss which properties that transactions should have for their correct executions. Provide two examples to support your answer.
Explanation:
A transaction is a very small system unit that can contain many low-level tasks. A transaction in a database system should maintain, Atomicity, Consistency, Isolation, and Durability − these are commonly known as ACID properties − in order to ensure accuracy, completeness, and integrity of the data.
An example of a simple transaction is as below, Suppose a bank employee transfers Rs 500 from A's account to B's account.
A’s Account
Open_Account(A)
Old_Balance = A.balance
New_Balance = Old_Balance - 500
A.balance = New_Balance
Close_Account(A)
B’s Account
Open_Account(B)
Old_Balance = B.balance
New_Balance = Old_Balance + 500
B.balance = New_Balance
Close_Account(B)

Explanation:
Computers in a LAN are configured to use a symmetric key cipher within the LAN to avoid hardware address spoofing. This means that each computer share a different key with every other computer in the LAN. If there are 100 computers in this LAN, each computer must have at least:
a. 100 cipher keys
b. 99 cipher keys
c. 4950 cipher keys
d. 100000 cipher keys
Answer:
The correct answer is option (c) 4950 cipher keys
Explanation:
Solution
Given that:
From the given question we have that if there are 100 computers in a LAN, then each computer should have how many keys.
Now,
The number of computers available = 100
The number of keys used in symmetric key cipher for N parties is given as follows:
= N(N-1)/2
= 100 * (100 -1)/2
= 50 * 99
= 4950 cipher keys

Assume that you have a list of n home maintenance/repair tasks (numbered from 1 to n ) that must be done in numeric order on your house. You can either do each task i yourself at a positive cost (that includes your time and effort) of c[i] . Alternatively, you could hire a handyman who will do the next 4 tasks for the fixed cost h (regardless of how much time and effort those 4 tasks would cost you). The handyman always does 4 tasks and cannot be used if fewer than four tasks remain. Create a dynamic programming algorithm that finds a minimum cost way of completing the tasks. The inputs to the problem are h and the array of costs c[1],...,c[n] .
a) Find and justify a recurrence (without boundary conditions) giving the optimal cost for completing the tasks. Use M(j) for the minimum cost required to do the first j tasks.
b) Give an O(n) -time recursive algorithm with memoization for calculating the M(j) values.
c) Give an O(n) -time bottom-up algorithm for filling in the array.
d) Describe how to determine which tasks to do yourself, and which tasks to hire the handyman for in an optimal solution.
Answer:
Explanation:
(a) The recurrence relation for the given problem is :
T(n) = T(n-1) + T(n-4) + 1
(b) The O(n) time recursive algorithm with memoization for the above recurrence is given below :
Create a 1-d array 'memo' of size, n (1-based indexing) and initialize its elements with -1.
func : a recursive function that accepts the cost array and startingJobNo and returns the minimum cost for doing the jobs from startingJobNo to n.
Algorithm :
func(costArr[], startingJobNo){
if(startingJobNo>n)
then return 0
END if
if(memo[startingJobNo] != -1)
then return memo[startingJobNo];
END if
int ans1 = func(costArr, startingJobNo+1) + costArr[startingJobNo]
int ans2 = func(costArr, startingJobNo+4) + h
memo[startingJobNo] = min(ans1,ans2);
return memo[startingJobNo];
}
(c)
First, Create a 1-d array 'dp' of size, N+1.
dp[0] = 0
bottomUp(int c[]){
for i=1 till i = n
DO
dp[i] = min(dp[i-1] + c[i], dp[max(0,i-4)] + h);
END FOR
return dp[n];
}
(d)
Modifying the algorithm given in part (b) as follows to know which job to do yourself and in which jobs we need to hire a handyman.
First, Create a 1-d array 'memo' of size, n (1-based indexing) and initialize its elements with -1.
Next, Create another 1-d array 'worker' of size,n (1-based indexing) and initialize its elements with character 'y' representing yourself.
Algorithm :
func(costArr[], startingJobNo){
if(startingJobNo>n)
then return 0
END if
if(memo[startingJobNo] != -1)
then return memo[startingJobNo];
END if
int ans1 = func(costArr, startingJobNo+1) + costArr[startingJobNo]
int ans2 = func(costArr, startingJobNo+4) + h
if(ans2 < ans1)
THEN
for (i = startingJobNo; i<startingJobNo+4 and i<=n; i++)
DO
// mark worker[i] with 'h' representing that we need to hire a mechanic for that job
worker[i] = 'h';
END for
END if
memo[startingJobNo] = min(ans1,ans2);
return memo[startingJobNo];
}
//the worker array will contain 'y' or 'h' representing whether the ith job is to be done 'yourself' or by 'hired man' respectively.
Write a function to_pig_latin that converts a word into pig latin, by: Removing the first character from the start of the string, Adding the first character to the end of the string, Adding "ay" to the end of the string. So, for example, this function converts "hello"to "ellohay". Call the function twice to demonstrate the behavior. There is a worked example for this kind of problem.
Answer:
def to_pig_latin(word):
new_word = word[1:] + word[0] + "ay"
return new_word
print(to_pig_latin("hello"))
print(to_pig_latin("latin"))
Explanation:
Create a function called to_pig_latin that takes one parameter, word
Inside the function, create a new_word variable and set it to the characters that are between the second character and the last character (both included) of the word (use slicing) + first character of the word + "ay". Then, return the new_word.
Call the to_pig_latin function twice, first pass the "hello" as parameter, and then pass the "latin" as parameter
