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
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.

Explanation:
Create an interface called Runner. The interface has an abstract method called run() that displays a message describing the meaning of run to the class. Create classes called Machine, Athlete, and PoliticalCandidate that all implement Runner.
The run() should print the following in each class:
Machine - When a machine is running, it is operating.
Athlete - An athlete might run in a race, or in a game like soccer.
PoliticalCandidate - A political candidate runs for office.
----------------------------------------------------------------------------------------------------
public class Athlete implements Runner
{
public void run()
{
// write your code here
}
}
--------------------------------------------------------------------------------------
public class DemoRunners
{
public static void main(String[] args)
{
Machine runner1 = new Machine();
Athlete runner2 = new Athlete();
PoliticalCandidate runner3 = new PoliticalCandidate();
runner1.run();
runner2.run();
runner3.run();
}
}
------------------------------------------------------------------------------------------
public class Machine implements Runner

public void run()
{
// write your code here
}
}
----------------------------------------------------------------------------------------------------
public class PoliticalCandidate implements Runner
{
public void run()
{
// write your code here
}
}
----------------------------------------------------------------------------------------------------
public interface Runner
{
// write your code here
}
----------------------------------------------------------------------------------------------------
Answer:
Here is the interface Runner:
public interface Runner { //interface Runner
public abstract void run(); } //abstract method run that displays a message describing the meaning of run to the class
/*Here Runner is the interface which is an abstract class. It is used to group related methods such as here is run method with empty body. An abstract method run() does not have a body. The body is provided by the sub classes Machine, Athlete, and PoliticalCandidate that all implement Runner. */
Explanation:
Here is the Athlete class:
public class Athlete implements Runner { //class that implements Runner interface
public void run() { //interface method accessed by Athlete to provide its body according to describe the meaning of run to the class
System.out.println("An athlete might run in a race, or in a game like soccer."); } } //prints this message
Here is the Machine class:
public class Machine implements Runner {
public void run() {
System.out.println("When a machine is running, it is operating."); }}
Here is the PoliticalCandidate class:
public class PoliticalCandidate implements Runner {
public void run() {
System.out.println("A political candidate runs for office."); } }
/*To access the interface Runner method run(), the Runner must be "implemented" by Machine, Athlete, and PoliticalCandidate classes with the implements keyword. The body of the interface method run() is provided by the "implement" class */
Here is the DemoRunners class:
public class DemoRunners { //class name
public static void main(String[] args) { //start of main method
Machine runner1 = new Machine(); //creates object of Machine class
Athlete runner2 = new Athlete(); //creates object of Athlete class
PoliticalCandidate runner3 = new PoliticalCandidate(); //creates object of PoliticalCandidate class
runner1.run(); //uses object of Machine class to call run method
runner2.run(); //uses object of Athlete class to call run method
runner3.run(); } } //uses object of PoliticalCandidate class to call run method
When runner1.run() is called it invokes the run() method of class Machine which displays the message:
When a machine is running, it is operating.
When runner2.run() is called it invokes the run() method of class Athlete which displays the message:
An athlete might run in a race, or in a game like soccer.
When runner3.run() is called it invokes the run() method of class PoliticalCandidate which displays the message:
A political candidate runs for office.

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.
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
The screenshot of the program along with its output is attached.

The government of a country wants to know how much inbound tourism (number of tourists visiting from other countries) is contributing to the country’s economic prosperity. The research firm hired to conduct this study surveys 10,000 residents on their favorite spots to visit in the country and how much money they spend on leisurely activities
a. How could the use of a sample like this threaten the value of the study’s outcomes?
b. How might the flawed sample affect the usefulness of the results?
Answer and Explanation:
A. The study by the research team may not reflect the purpose of the research which is to know how much inbound tourism is contributing to the economy. They are sampling the population on their favorite spots to visit( which may be too narrow here) and what their leisure activities are (which are not the only things tourists spend on). Also 10000 residents may be too small as a sample to reflect more accurate study outcome representative of the population.
2. A flawed sample which is a sampling error would not represent the population as the results from sample would contradict population results

The two statements belowchar dance1[ ] = {'F','o','x','t','r','o','t'};String dance2 = new String(dance1);will generate an error message:
a. because char variables and String variable do not mix.
b. will generate an error message because char variables and String variable do not mix.
c. show that a String variable, like dance2, is an array.
d. demonstrate that a character array can be used to construct a String object.
e. prove that character variables and String variables are identical.
Answer:
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

A country, called Simpleland, has a language with a small vocabulary of just “the”, “on”, “and”, “go”, “round”, “bus”, and “wheels”. As per the given scenario, the vector of counts will be 2111211. The correct option is C.
What are the ways to count items in a vector?C++ has a built-in function that counts the length of the vector. Size is the function's name ().
It returns the size or total number of elements of the vector that was utilized to create it. There is no need for debate.
The number of observations (rows) includes deleted observations as well. In an SAS data collection, there can be a maximum of 2 63-1 observations, or roughly 9.2 quintillion observations. For the majority of users, going above that limit is quite rare.
The vector of counts in the above scenario will be 2111211.

So, the code to print these elements is as follows:
Console.log(userArray[1]);
Console.log(userArray[4]);
