Ann. An employee in the payroll department, has contacted the help desk citing multiple issues with her device, including: Slow performance Word documents, PDFs, and images no longer opening A pop-up Ann states the issues began after she opened an invoice that a vendor emailed to her. Upon opening the invoice, she had to click several security warnings to view it in her word processor. With which of the following is the device MOST likely infected?
a. Spyware
b. Crypto-malware
c. Rootkit
d. Backdoor
Answer:
d. Backdoor
Explanation:
A backdoor is a type of malware that overrides security checks and authentications to access a computer or embedded device.
When this is done, remote access is granted and databases and servers can be accessed and modified. Attackers can also give remote commands to the system.
What happened to Ann in the payroll department is probably a backdoor attack that affected her device.
Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print:
90, 92, 94, 95
Note that the last element is not followed by a comma, space, or newline.
#include
using namespace std;
int main() {
const int NUM_VALS = 4;
int hourlyTemp[NUM_VALS];
int i = 0;
hourlyTemp[0] = 90;
hourlyTemp[1] = 92;
hourlyTemp[2] = 94;
hourlyTemp[3] = 95;
/* Your solution goes here */
cout << endl;
return 0;
}
Answer:
string sep = "";
for (i = 0; i < NUM_VALS; i++) {
cout << sep << hourlyTemp[i];
sep = ", ";
}
Explanation:
Insert the snippet at the commented location.
With the absence of a join() method as found in other languages, it is always a hassle to suppress that separator comma from appearing at the beginning or the end of your output. This solution is nice since it doesn't require any magic flags to keep track of wether the first element was printed.

g Write a method that accepts a String object as an argument and displays its contents backward. For instance, if the string argument is "gravity" the method should display -"ytivarg". Demonstrate the method in a program that asks the user to input a string and then passes it to the method.
Answer:
The program written in C++ is as follows; (See Explanation Section for explanation)
#include <iostream>
using namespace std;
void revstring(string word)
{
string stringreverse = "";
for(int i = word.length() - 1; i>=0; i--)
{
stringreverse+=word[i];
}
cout<<stringreverse;
}
int main()
{
string user_input;
cout << "Enter a string: ";
getline (std::cin, user_input);
getstring(user_input);
return 0;
}
Explanation:
The method starts here
void getstring(string word)
{
This line initializes a string variable to an empty string
string stringreverse = "";
This iteration iterates through the character of the user input from the last to the first
for(int i = word.length() - 1; i>=0; i--) {
stringreverse+=word[i];
}
This line prints the reversed string
cout<<stringreverse;
}
The main method starts here
int main()
{
This line declares a string variable for user input
string user_input;
This line prompts the user for input
cout << "Enter a string: ";
This line gets user input
getline (std::cin, user_input);
This line passes the input string to the method
revstring(user_input);
return 0;
}
Each time we add another bit, what happens to the amount of numbers we can make?
Answer:
When we add another bit, the amount of numbers we can make multiplies by 2. So a two-bit number can make 4 numbers, but a three-bit number can make 8.
The amount of numbers that can be made is multiplied by two for each bit to be added.
The bit is the most basic unit for storing information. Bits can either be represented as either 0 or 1. Data is represented by using this multiple bits.
The amount of numbers that can be gotten from n bits is given as 2ⁿ.
Therefore we can conclude that for each bit added the amount of numbers is multiplied by two (2).

If the data rate is 10 Mbps and the token is 64 bytes long (the 10-Mbps Ethernet minimum packet size), what is the average wait to receive the token on an idle network with 40 stations? (The average number of stations the token must pass through is 40/2 = 20.) Ignore the propagation delay and the gap Ethernet requires between packets.
Answer:
1.024x10^-5
Explanation:
To calculate the transmission delay bytes for the token,
we have the token to be = 64bytes and 10mbps rate.
The transmission delay = 64bytes/10mbps
= 51.2 microseconds
A microsecond is a millionth of a second.
= 5.12 x 10^-5
The question says the average number of stations that the token will pass through is 20. Remember this value is gotten from 40/2
20 x 5.12 x 10^-5
= 0.001024
= 1.024x10^-5
Therefore on an idle network with 40 stations, the average wait is
= 1.024x10^-5

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6's Programming Challenge 4. The CashRegister class should simulate the sale of a retail item. It should have a constructor that accepts a RetailItem object as an argument. The constructor should also accept an integer that represents the quantity of items being purchased. In addition, the class should have the following methods:
• The getSubtotal method should return the subtotal of the sale, which is the quantity multiplied by the price. This method must get the price from the RetailItem object that was passed as an argument to the constructor.
• The getTax method should return the amount of sales tax on the purchase. The sales tax rate is 6 percent of a retail sale.
• The getTotal method should return the total of the sale, which is the subtotal plus the sales tax.
Demonstrate the class in a program that asks the user for the quantity of items being purchased and then displays the sale’s subtotal, amount of sales tax and total.
Answer:
Following are the code to this question:
import java.util.*; //import package for user input
class RetailItem//defining class RetailItem
{
private String desc;//defining String variable
private int unit;//defining integer variable
private double prices;//defining double variable
RetailItem()//defining default Constructor
{
//Constructor body
}
Output:
The Sub Total value: 199.75
The Sales Tax value: 11.985
The Total value: $211.735
Explanation:
In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.
In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.
In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".

The intention of this problem is to analyze a user input word, and display the letter that it starts with (book → B).
a. Create a function prototype for a function that accepts a word less than 25 characters long, and return a character.
b. Write the function definition for this function that evaluates the input word and returns the letter that the word starts with in capital letter (if it’s in small letters).
c. Create a function call in the main function, and use the function output to print the following message based on the input from the user. (Remember to have a command prompt in the main function requesting the user to enter any word.)
Computer starts with the letter C.
Summer starts with the letter S.
d. Make sure to consider the case where a naughty user enters characters other than the alphabet to form a word and display a relevant message.
%sb$ is not a word.
$500 is not a word.
e. Have the program process words until it encounters a word beginning with the character
Answer:
Here is the C++ program:
#include<iostream> // to use input output functions
using namespace std; //to identify objects like cin cout
void StartChar(string str) { // function that takes a word string as parameter and returns the first letter of that word in capital
int i;
char c;
do //start of do while loop
{
for (int i = 0; i < str.length(); i++) { //iterates through each character of the word str
if(str.length()>25){ //checks if the length of input word is greater than 25
cout<<"limit exceeded"; } //displays this message if a word is more than 25 characters long
c = str.at(i); // returns the character at position i
if (! ( ( c >= 'a' && c <= 'z' ) || ( c >= 'A' && c <= 'Z' ) ) ) { //checks if the input word is contains characters other than the alphabet
cout<<str<<" is not a word!"<<endl; break;} //displays this message if user enters characters other than the alphabet
if (i == 0) { //check the first character of the input word
str[i]=toupper(str[i]); //converts the first character of the input word to uppercase
cout<<str<<" starts with letter "<<str[i]<<endl; } // prints the letter that the word starts with in capital letter
} cout<<"Enter a word: "; //prompts user to enter a word
cin>>str; //reads input word from user
}while(str!="#"); } //keeps prompting user to enter a word until the user enters #
int main() //start of the main() function body
{ string str; //declares a variable to hold a word
cout<<"Enter a word: "; //prompts user to enter a word
cin>>str; //reads input word from user
StartChar(str); } //calls function passing the word to it
Explanation:
The program prompts the user to enter a word and then calls StartChar(str) method by passing the word to the function.
The function StartChar() takes that word string as argument.
do while loop starts. The for loop inside do while loop iterates through each character of the word string.
First if condition checks if the length of the input word is greater than 25 using length() method which returns the length of the str. For example user inputs "aaaaaaaaaaaaaaaaaaaaaaaaaaa". Then the message limit exceeded is printed on the screen if this if condition evaluates to true.
second if condition checks if the user enters anything except the alphabet character to form a word. For example user $500. If this condition evaluates to true then the message $500 is not a word! is printed on the screen.
Third if condition checks if the first character of input word, convert that character to capital using toupper() method and prints the first letter of the str word in capital. For example if input word is "Computer" then this prints the message: Computer starts with the letter C in the output screen.
The program keeps prompting the user to enter the word until the user enters a hash # to end the program.
The output of the program is attached.
Raj was concentrating so much while working on his project plan that he was late for a meeting. When he went back to his office, he noticed his system was restarted and his project file was not updated. What advice would you provide Raj in this situation?
Answer:
Explanation:
Depending on the software that Raj was using to create his project he should first see if the software itself saved the project. Usually many software such as those included in the Microsoft Office Suite save the file automatically every 5 minutes or so in case of a power outage or abrupt closure of the file. If this is not the case he should try and do a system restore with the unlikely hope that it restores an older version of his project.
In a situation like this, it would be advisable for Raj to contact IT personnels and seek if the files could be retrieved.
Raj being late for a meeting due to what he was doing meant that the project he was working on is very important. Therefore, to avoid losing thses files, he could contact the IT personnels and request if there is a way to retrieve the project file.These way, the files could be retrieved and avoid losing his work.

Write a Bash script that searches all .c files in the current directory (and its subdirectories, recursively) for occurrences of the word "foobar". Your search should be case-sensitive (that applies both to filenames and the word "foobar"). Note that an occurrence of "foobar" only counts as a word if it is either at the beginning of the line or preceded by a non-word-constituent character, or, similarly, if it is either at the end of the line or followed by a non-word- constituent character. Word-constituent characters are letters, digits and underscores.
Answer:
grep -R '^foobar'.c > variable && grep -R 'foobar$'.c >> variable
echo $variable | ls -n .
Explanation:
Bash scripting is a language used in unix and linux operating systems to interact and automate processes and manage files and packages in the system. It is an open source scripting language that has locations for several commands like echo, ls, man etc, and globbing characters.
The above statement stores and appends data of a search pattern to an already existing local variable and list them numerically as standard out 'STDOUT'.

Write a program that asks the user to enter a series of numbers separated by commas. Here is an example of valid input: 7,9,10,2,18,6 The program should calculate and display the sum of all the numbers.
Answer:
Here is the JAVA program. Let me know if you need the program in some other programming language.
import java.util.Scanner; // used for taking input from user
public class Main{ //Main class
public static void main(String[] args) {//start of main() function body
Scanner scan = new Scanner(System.in); // creates a Scanner type object
String input; // stores input series
int sum = 0; //stores the sum of the series
System.out.println("Enter a series of numbers separated by commas: "); //prompts user to enter a series of numbers separated by comma
input = scan.nextLine(); //reads entire input series
String[] numbers = input.split("[, ]"); //breaks the input series based on delimiter i.e. comma and stores the split sub strings (numbers) into the numbers array
for (int i = 0; i < numbers.length; i++) { //loops through each element of numbers array until the length of the numbers reaches
sum += Integer.parseInt(numbers[i]); } // parses the each String element of numbers array as a signed decimal integer object and takes the sum of all the integer objects
System.out.println("Sum of all the numbers: " + sum); } } //displays the sum of all the numbers
Explanation:
The program prompts the user to enter a series separated by commas.
Then split() method is used to split or break the series of numbers which are in String form, into sub strings based on comma (,) . This means the series is split into separate numbers. These are stored in numbers[] array.
Next the for loop iterate through each sub string i.e. each number of the series, converts each String type decimal number to integer using Integer.parseInt and computes the sum of all these integers. The last print statement displays the sum of all numbers in series.
If the input is 7,9,10,2,18,6
Then the output is: 7+9+10+2+18+6
sum = 52
The program and its output is attached.
Define a function readList with one parameter, the (string) name of a file to be read from. The file consists of integers, one per line. The function should return a list of the integers in the file.
Answer:
Here is the Python function readList:
def readList(filename): #function definition of readList that takes a filename as a parameter and returns a list of integers in the file
list = [] # declares an empty list
with open(filename, 'r') as infile: # opens the file in read mode by an object infile
lines = infile.readlines() # returns a list with each line in file as a list item
for line in lines: #loops through the list of each line
i = line[:-1] # removes new line break which is the last character of the list of line
list.append(i) # add each list item i.e. integers in the list
return list #returns the list of integers
#in order to check the working of the above function use the following function call and print statement to print the result on output screen
print(readList("file.txt")) #calls readList function by passing a file name to it
Explanation:
The program is well explained in the comments mentioned with each line of the code.
The program declares an empty list.
Then it opens the input file in read mode using the object infile.
Next it uses readLines method which returns a list with each line of the file as a list item.
Next the for loop iterates through each item of the file which is basically integer one per line
It adds each item of list i.e. each integers in a line to a list using append() method.
Then the function returns the list which is the list of integers in the file.
The program along with it output is attached. The file "file.txt" contains integers 1 to 8 one per line.
