D. Demonstrate that a character array can be used to construct a String object.

Explanation:

Option D answers the question.

This is so because:

The first line of the code segment creates a char array element i.e. dance1

The second line of the code segment creates a String variable, dance2.

dance2 is then initialised by concatenating the elements in dance1.

i.e. The value of dance2 is

dance2 = "Foxtrot"

Hence, option D answers the question

The answer to this question is data bar. Through the use of a day bar we are able to see trends in our data. They are very useful when it comes to visualization of values that are In a range of cells. Now if the bar is longer then the value we are visualizing is definitely higher. And if it is shorterr the value is lower. Several applications like excel has programmes that makes use of data bars especially for statistical purposes.

Answer:

Console.log(userArray[1]);

Console.log(userArray[4]);

Explanation:

The programming language was not stated; however, the variable declaration implies JavaScript.

JavaScript prints using the following syntax:

Console.log(print-name);

Since, the code is to print some elements of array userArray.

First, we need to determine the index of the elements.

The indices are given as 1 and 4.

So, the code to print these elements is as follows:

Console.log(userArray[1]);

Console.log(userArray[4]);

Answer:

earned = 0

total = 0

exercises = int(input("Enter the number of exercises: "))

for i in range(exercises):

   score = int(input("Enter score" + str(i+1) + ": "))

   total_score = int(input("Enter total score for exercise " + str(i+1) + ": "))

   earned += score

   total += total_score

print("The total is %" + str(earned/total * 100))

Explanation:

*The code is in Python.

Set the earned and total as 0

Ask the user to enter the number of exercises

Create a for loop that iterates number of exercises times. For each exercise;

Ask the user to enter the score earned and total score of that exercise

Add the score to the earned (cumulative sum)

Add the total_score to the total (cumulative sum)

When the loop is done, calculate the percentage, divide earned by the total and multiply the result by 100, and print it

I've implemented this program using python

mylist.append(userinput)

for i in range(1,userinput+1):

   userinp = int(input("Input: "))

   mylist.append(userinp)

smallval = mylist[1]

for i in range(1,len(mylist)):

   if smallval > mylist[i]:

       smallval = mylist[i]

for i in range(1,len(mylist)):

   mylist[i] = mylist[i] - smallval

for i in range(1,len(mylist)):

   print(mylist[i],end=' ')

Explanation:

I've added the full source program as an attachment where I used comments to explain difficult lines

The program written in python 3 deducts the least from a list of user given integers and prints the output. The program goes thus :

len_input = int(input())

#the number of inputs the user wishes to supply

vals = []

#initialize an empty list to accept the inputs

for i in range(1, len_input +1):

#use a loop to accept the user inputs

num = int(input())

#allow users to take in the inputs

vals.append(num)

#append each value to the list

least =min(vals)

#using the min function, obtain the lowest value from the list

output_vals = []

#initialize an empty list to hold the normalized values

for i in range(len_input):

#loop using a for loop

diff = vals[i] - least

#deduct the minimum value from each element in the list

output_vals.append(diff)

#append the values to the new list.

print(output_vals)

#display the output

A sample run of the program and the script is attached.

Examples of malware spreads include all of the options mentioned: social networks, pirated software, and removable media.

The correct option is d.

a. Social networks: Malware can spread through social networks via malicious links or infected attachments shared within messages, posts, or comments. Users may unknowingly click on these links or download infected files, which can then propagate the malware to their devices or their contacts.

b. Pirated software: Malicious actors often distribute malware-infected versions of popular software through illegitimate channels. Users who download and install pirated software are at risk of unknowingly introducing malware onto their systems, as these versions may be modified to include malicious code.

c. Removable media: Malware can also spread through removable media such as USB drives, external hard drives, or even CDs/DVDs. If an infected device or media is connected to a computer, the malware can transfer onto the system, potentially infecting files and spreading further.

Therefore, all of the options (a, b, and c) are examples of how malware can spread, highlighting the importance of practicing safe online habits, avoiding pirated software, being cautious with links and attachments, and regularly scanning removable media to mitigate the risk of malware infections.

Answer:  

Here is the C++ program:  

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

using namespace std;   //to identify objects cin cout    

int main() {   //start of main method    

int red,green,blue,smallest;   //declare variables to store integer values of red,green, blue and to store the smallest value    

cout<<"Enter value for red: ";  //prompts user to enter value for red    

cin>>red;  //reads value for red from user    

cout<<"Enter value for green: ";  //prompts user to enter value for green  

cin>>green; //reads value for green from user    

cout<<"Enter value for blue: "; //prompts user to enter value for blue    

cin>>blue;   //reads value for blue from user    

//computes the smallest value  

if(red<green && red<blue) //if red value is less than green and blue values    

smallest=red;   //red is the smallest so assign value of red to smallest    

else if(green<blue)   //if green value is less than blue value    

smallest=green; //green is the smallest so assign value of green to smallest  

else //this means blue is the smallest    

smallest=blue;  //assign value of blue to smallest    

//removes gray part by subtracting smallest from rgb  

red=red-smallest; //subtract smallest from red    

green=green-smallest; //subtract smallest from green    

blue=blue-smallest; //subtract smallest from blue    

cout<<"red after removing gray part: "<<red<<endl;  //displays amount of red after removing gray    

cout<<"green after removing gray part: "<<green<<endl; //displays amount of green after removing gray  

cout<<"blue after removing gray part: "<<blue<<endl;  } //displays amount of blue after removing gray  

Explanation:  

I will explain the program using an example.    

Lets say user enter 130 as value for red, 50 for green and 130 for blue. So  

red = 130    

green = 50

blue = 130  

First if condition if(red<green && red<blue)   checks if value of red is less than green and blue. Since red=130 so this condition evaluate to false and the program moves to the else if part else if(green<blue) which checks if green is less than blue. This condition evaluates to true as green=50 and blue = 130 so green is less than blue. Hence the body of this else if executes which has the statement: smallest=green;  so the smallest it set to green value.    

smallest = 50    

Now the statement: red=red-smallest; becomes:    

red = 130 - 50    

red = 80    

the statement: green=green-smallest;  becomes:    

green = 50 - 50    

green = 0    

the statement: blue=blue-smallest; becomes:    

blue = 130 - 50    

blue = 80    

So the output of the entire program is:    

red after removing gray part: 80                                                                                                 green after removing gray part: 0                                                                                                blue after removing gray part: 80

Computer store files in its temporary data storage space so as to facilitate easy retrievals when needed. Cache memory is in the temporary data storage space of the computer, faster than any other system memory so that when the processor requests information from the computer memory after a user place a command, the cache memory makes the information available in a short time when the data are required eliminating delay when ram will have to take time to fetch the data to provide to the processor.

In an asynchronous write, the data are stored in the cache to enable easy retrieval by the computer processor just as the cache is explained above, it allows writing data to the cluster. Asynchronous write also allows control returns to the caller.
