Privacy is considered keeping information about a network or system user from being disclosed to unauthorized people.A. TrueB. False

Answer:

Explanation:

As a computer science student, you should assess your vulnerability to information theft by analyzing the types of information you have and where you store it, as well as the security measures you have in place to protect that information. This includes things like passwords, two-factor authentication, and encryption.

A famous celebrity, on the other hand, may have a higher level of vulnerability to information theft due to their high-profile status and the fact that they may have more sensitive information such as financial information, personal contacts, and private photos and videos. They may also be targeted more frequently by hackers and scammers who are looking to exploit their fame and popularity.

It is important to note that everyone's vulnerability to information theft is different and it is important to take the necessary steps to protect your personal information, regardless of whether you are a computer science student or a famous celebrity. This includes keeping your software and operating system updated, being cautious when clicking on links or opening email attachments from unknown sources, and not sharing personal information online.

Here is the C# program.

using System;  //namespace for organizing classes

   public class Square  //Square class

//private fields/variables side and area of Square class

   {   private double side;  

       private double area;

//Side has read only property to get Square side

       public double Side {

           get { return this.side; }

       }  

//Area has read only property to get Square area

       public double Area {  

           get { return this.area; }         }  

/*constructor Square(double length) that requires a parameter for the length of one side of a Square. The constructor assigns its parameter to the length of the Square’s side field and calls a private method SquareArea() that computes the area field */

       public Square(double length)         {

           this.side = length;

           this.area = SquareArea();         }  

//method to calcuate area of a square

       private double SquareArea()         {

//Pow method is used to compute square the side i.e. side^2

           return Math.Pow(this.side, 2);         }     }          

   public class DemoSquares  {  

       public static void Main()  {   //start of main() function body  

//displays the side and area on output screen

           Console.WriteLine("{0}\t{1}\t{2}", "No.", "Side Length ", "Area");      

           //instantiates an array to input values 1 through 10 into Side            

           Square[] squares = new Square[10];   //squares is the instance

           for (int i = 1; i < squares.Length; i++) {  

//traverses through the squares array until the i exceeds the length of the //array

               squares[i] = new Square(i);  

//parameter is passed in the constructor

//new object is created as arrray is populated with null members

               Square sq = squares[i];

/*display the no, side of square in area after setting the alignment to display the output in aligned way and with tab spaces between no side and area */

               Console.WriteLine("{0}\t{1,11}\t{2,4}",  i, sq.Side, sq.Area); }  

//ReadKey method is used to make the program wait for a key press from //the keyboard

           Console.ReadKey();         }     }

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The program simply has Square class which contains area and length of side as fields and a constructor Square which has length of one side of Square as parameter and assigns its parameter to length of Square side. The a private method SquareArea() is called that computes the area field. get methods are used to include read-only properties to get a Square’s side and area. The program along with its output is attached in the screenshot.

The expression "2 << 6" is equivalent to multiplying 2 by 2^6, which is 64. So, "2 << 6" results in 64. The bitwise NOT operator () flips all the bits of the expression that follows it, and the bitwise AND operator (&) performs a logical AND between the original value of A and the result of the NOT operation.

The compiler replaces a division operation with a multiplication and a bit shift operation, which are faster operations on most computer architectures. This technique can significantly speed up integer division by constants.

   if s == "ZZZ":

       break

   if len(s) <= 10:

       short_strings.append(s)

   elif len(s) >= 11:

   else:

       print(long_strings)

Explanation:

*The code is in Python.

Initialize the count, i, short_strings, and long_strings

Create a while loop that iterates 20 times.

Inside the loop:

Ask the user to enter a string. If the string is "ZZZ", stop the loop. If the length of the string is smaller than or equal to 10, add it to the short_strings. If the length of the string is greater than or equal to 11, add it to the long_strings. Increment the value of i by 1.

When the loop is done:

Ask the user to enter the list type to display.

If the user enters "short", print the short list. Otherwise, print the long_strings. Also, if the length of the  chosen string is equal to 0, print that the list is empty.

Answer:

The database on a mobile device containing bands, sub-bands, and service provider IDs that allow the device to establish a connection with the right cell phone tower is called a "Preferred Roaming List" (PRL).

Explanation:

The PRL is a database maintained by the mobile network operator (MNO) and stored on the mobile device. It contains information about the bands and sub-bands supported by the MNO's network and the service provider IDs of roaming partners. When a mobile device is searching for a signal, it consults the PRL to determine which network frequencies and towers are available and compatible with the device.

The PRL is periodically updated by the MNO to reflect changes in network coverage and roaming agreements. Updates to the PRL can be pushed to the device over-the-air (OTA) or manually installed through a software update or by calling the carrier's customer service.

In this case, a bar chart would be the most suitable type of chart to illustrate and compare the popularity of all the ice cream flavors.

A bar chart is effective in displaying categorical data and comparing the values of different categories. Each flavor can be represented by a separate bar, and the height or length of the bar corresponds to the popularity or frequency of that particular flavor. This allows for easy visual comparison between the flavors and provides a clear indication of which flavors are more popular based on the relative heights of the bars.

Given that there are 25 different ice cream flavors, a bar chart would provide a clear and concise representation of the popularity of each flavor. The horizontal axis can be labeled with the flavor names, while the vertical axis represents the frequency or number of respondents who selected each flavor as their favorite. This visual representation allows for quick insights into the most popular flavors, any potential trends, and a clear understanding of the distribution of preferences among the survey participants.

On the other hand, a scatter plot would not be suitable for this scenario as it is typically used to show the relationship between two continuous variables. Pie charts are more appropriate for illustrating the composition of a whole, such as the distribution of flavors within a single respondent's choices. Line charts are better for displaying trends over time or continuous data.

Therefore, a bar chart would be the most effective and appropriate choice to illustrate and compare the popularity of all the ice cream flavors in the given survey.

Add this code the the /* Your solution goes here */  part of program:

for (int i=0; i<3; i++) { //iterates through the 3-character passCode

  if (isdigit(passCode[i])) //uses isdigit() method to check if character is a digit

           hasDigit = true;    } //sets the value of hasDigit to true when the above if condition evaluates to true

Explanation:

Here is the complete program:

#include <iostream> //to use input output functions

using namespace std; // to identify objects like cin cout

int main() { // start of main function

bool hasDigit; // declares a bool type variable  

string passCode; //declares a string type variable to store 3-character passcode

hasDigit = false; // sets the value of hasDigit as false initially

cin >> passCode; // reads the pass code from user

for (int i=0; i<3; i++) { //iterate through the 3 character pass code

   if (isdigit(passCode[i])) // checks if any character of the 3-character passcode contains a digit

     hasDigit = true;    }      //sets the value of hasDigit to true if the passcode contains a digit    

if (hasDigit) { // if pass code has a digit

cout << "Has a digit." << endl;} //displays this message when passcode has a digit

else { //if pass code does not have a digit

cout << "Has no digit." << endl;} //displays this message when passcode does not have a digit

return 0;}

I will explain the program with an example. Lets say the user enters ab1 as passcode. Then the for loop works as follows:

At first iteration:

i = 0

i<3 is true because i=0

if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to false because passCode[0] points to the first character of pass code i.e. a which is not a digit. So the value of i is incremented to 1

At second iteration:

i = 1

i<3 is true because i=1

if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to false because passCode[1] points to the second character of pass code i.e. b which is not a digit. So the value of i is incremented to 1

At third iteration:

i = 2

i<3 is true because i=2

if (isdigit(passCode[i]) this if statement has a method isdigit which is passed the i-th character of passCode to check if that character is a digit. This condition evaluates to true because passCode[3] points to the third character of pass code i.e. 1 which is a digit. So the hasDigit = true;  statement executes which set hasDigit to true.

Next, the loop breaks at i=3 because value of i is incremented to 1 and the condition i<3 becomes false.

Now the statement if (hasDigit) executes which checks if hasDigit holds. So the value of hasDigit is true hence the output of the program is:

Has a digit.

Complete question:

Scrabble is a word game in which words are constructed from letter tiles, each letter tile containing a point value. The value of a word is the sum of each tile's points added to any points provided by the word's placement on the game board. Write a program using the given dictionary of letters and point values that takes a word as input and outputs the base total value of the word (before being put onto a board). Ex:  If the input is:  PYTHON

the output is: 14

part of the code:

tile_dict = { 'A': 1, 'B': 3, 'C': 3, 'D': 2, 'E': 1, 'F': 4, 'G': 2, 'H': 4, 'I': 1, 'J': 8,  'K': 5, 'L': 1, 'M': 3, 'N': 1, 'O': 1, 'P': 3, 'Q': 10, 'R': 1, 'S': 1, 'T': 1,  'U': 1, 'V': 4, 'W': 4, 'X': 8, 'Y': 4, 'Z': 10 }

Answer:

Complete the program as thus:

word = input("Word: ").upper()

points = 0

for i in range(len(word)):

   for key, value in tile_dict.items():

       if key == word[i]:

           points+=value

           break

print("Points: "+str(points))

Explanation:

This gets input from the user in capital letters

word = input("Word: ").upper()

This initializes the number of points to 0

points = 0

This iterates through the letters of the input word

for i in range(len(word)):

For every letter, this iterates through the dictionary

   for key, value in tile_dict.items():

This locates each letters

       if key == word[i]:

This adds the point

           points+=value

The inner loop is exited

           break

This prints the total points

print("Points: "+str(points))

Answer:

Here is the exact code, especially if you want it as Zybooks requires

Explanation:

word = input("").upper()

Explanation:

Literally, the rank function is used to rank values (i.e. cells) in a particular order (either ascending or descending).

Take the following instances:

A column used for total sales can use rank function to rank its cells from top sales to least.

A cell used for time can also use the rank function to rank its cells from the fastest time to slowest.

The syntax of the rank function is:

=RANK (number, ref, [order])

Which means:

\(number \to\) The rank number

\(ref \to\) The range of cells to rank

\(order \to\) The order of ranking i.e. ascending or descending. This is optional.

All array indexes begin with the largest item in the array. The correct option is C.

A grouping of comparable types of data is called an array. For instance, we can create an array of the string type that can hold 100 names if we need to record the names of 100 different persons.

Since modern programming languages' array indices typically begin at 0, computer programmers may use zeroth in places where others may use first, and so on. As a result, the array's index starts at 0, since I initially denote the array's first element.

Therefore, the correct option is C. With the largest item in the array.

So, we analyze each of the options using Python syntax

(a) listB.clear(3)

In python, clear() is used to delete all elements of a list, and it does not take any argument i.e. nothing will be written in the bracket.

Hence, (a) is incorrect

(b) listB(3)

The above instruction has no meaning in Python

(c) listB delete(3)

The above instruction as written is an invalid syntax because of the space between listB and delete.
