Explanation:

The program is well explained in the comments mentioned with each line of the program. The program uses while loop that keeps asking user to select an operator and two operands to perform arithmetic calculations. The if conditions are used to check what arithmetic calculation is to be performed based on user choice of operand and calls the relevant function to perform calculation. There are five functions that perform addition, modulo, subtraction, division and multiplication and display the result of computation. The screenshot of output is attached.

what are the example of malware spreads

c.removable media
d. all of the above​

Answers

The answer has to be
D. All of the above

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.

Adjust list by normalizing When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain fewer than 20 integers. Ex: If the input is: 5 30 50 10 70 65 the output is: 20 40 0 60 55 The 5 indicates that there are five values in the list, namely 30, 50, 10, 70, and 65. 10 is the smallest value in the list, so is subtracted from each value in the list. For coding simplicity, follow every output value by a space, including the last one.

Remove gray from RGB Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part.

Answers

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

In __________ write, the data are stored in the cache, and control returns to the caller. Select one: a. a synchronous b. a buffered c. an asynchronous d. a non-buffered

Answers

Answer:

The correct answer to the question is option C (an asynchronous)

Explanation:

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.

Because the decision support systems process the data, evaluate and predict the decision, and helps the decision-makers,  and offer real-time information immediately in making the decision in an organization. So the correct answer to this question is the decision supports system.

Why other options are not correct

Because the transaction processing system can only process the transaction and have not the capability to make the decision for the future. Office support processing system support office work, while the batch processing system process the task into the batch without user involvement.   however, online executive processing does not make decisions and offer timely information to decision-makers in an organization.

A have a string, called "joshs_diary", that is huge (there was a lot of drama in middle school). But I don't want every one to know that this string is my diary. However, I also don't want to make copies of it (because my computer doesn't have enough memory). Which of the following lines will let me access this string via a new name, but without making any copies?

a. std::string book = joshs_diary;
b. std::string & book = joshs_diary; const
c. std::string * book = &joshs_diary;
d. std::string book(joshs_diary);
e. const std::string & book = joshs_diary;
f. const std::string * const book = &joshs_diary;
g. std::string * book = &joshs_diary;

Answer:

C and G

Explanation:

In C language, the asterisks, ' * ', and the ampersand, ' & ', are used to create pointers and references to pointers respectively. The asterisks are used with unique identifiers to declare a pointer to a variable location in memory, while the ampersand is always placed before a variable name as an r_value to the pointer declared.

In Java, the import statement is used to include classes or packages from outside sources in your code. This lets you access and use the features of those classes or packages.

What is the JOptionPane

To do the above, You need to import JOptionPane in Java because it belongs to a different package from the Math class.

The Math class is a part of the java. lang package, which is automatically included in Java. This package has important classes and interfaces that are used in Java programs. Because the Math class is already included in this package, you don't have to import it separately.
