Consider the following class definitions. public class Computer { private String memory; public Computer) { memory = "RAM"; } public Computer (String m) { memory = m; } public String getMemory () { return memory; ) } public class Smartphone extends Computer private double screenWidth, screenHeight; public Smart Phone (double w, double h) super("flash"); screenWidth = w; screenHeight = h; } public double get ScreenWidth() { return screenWidth; } public double getScreenHeight() { } return screenHeight; } The following code segment appears in a class other than Computer or Smartphone. + Computer myPhone = new Smart Phone (2.55, 4.53); System.out.println("Device has memory: " + myPhone.getMemory () ", screen area: " + myPhone.getScreenWidth()* myPhone.getScreenHeight() + " square inches."); The code segment is intended to produce the following output. Device has memory: flash, screen area: 11.5515 square inches. Which of the following best explains why the code segment does not work as intended?A. An error occurs during compilation because a Smartphone object cannot be assigned to the Computer reference variable myPhone. B. An error occurs during compilation because the Smartphone class has no getMemory method. C. An error occurs during compilation because the getScreenWidth and getScreenHeight methods are not defined for the Computer object myPhone. D. An error occurs at runtime because the Smartphone class has no getMemory method. E. An error occurs at runtime because the getScreenWidth and getScreenHeight methods are not defined for the Computer object myPhone.
Answer:
C.
Explanation:
The code provided in the question has many syntax errors. I have pasted a fixed version of the code below that fixes all the syntax errors but leaves the code as is. Using this code you can see that the error that is preventing the code from running properly is that
C. An error occurs during compilation because the getScreenWidth and getScreenHeight methods are not defined for the Computer object myPhone.
As you can see from the attached photo below, the code is failing to compile because the methods themselves are not able to be accessed by the myPhone object. This is happening during the compilation and thus causing the compilation to fail.
class Computer {
private String memory;
public Computer() {
memory = "RAM";
}
public Computer(String m) {
memory = m;
}
public String getMemory() {
return memory;
}
}
class Smartphone extends Computer {
private double screenWidth, screenHeight;
public Smartphone(double w, double h) {
super("flash");
screenWidth = w;
screenHeight = h;
}
public double getScreenWidth() {
return screenWidth;
}
public double getScreenHeight() {
return screenHeight;
}
}
public class Main{
//The following code segment appears in a class other than Computer or Smartphone
public static void main(String[] args) {
Computer myPhone = new Smartphone(2.55, 4.53);
System.out.println("Device has memory: " + myPhone.getMemory() + ", screen area: " + (myPhone.getScreenWidth()*myPhone.getScreenHeight()) +" square inches.");
}
}
The choice is "The getScreenWidth and getScreenHeight methods again for Computer object myPhone aren't declared, resulting in an error during compilation".
Class Description:In Options D and E errors would not occur since only compile-time errors, not run-time errors, would happen.Computer myPhone = new Smartphone(2.55,4.55);
A computer class was referenced by myPhone in this line. As a consequence, it's solely useful for computer students. Therefore, if you try to use the "getScreenwidth" and "getScreenHeight" functions of both the Smartphone class, which would be a sub-class of the Smartphone, you'll get an error. So, because the scope of the myPhone is limited to the parent class, the computer, it complies.Choices A and B will not produce an error since they are inside the scope of the myPhone.As a result, option C is the best argument for why the code section isn't working as it should.Find out more about the class here:

How do most benchmark tests measure the performance of a graphic card
Answer:
Using Frame Rate
Explanation:
Most benchmark tests measure the performance of a graphic card by using "Frame Rate"
This is because using Frame Rate assesses and then measures the number of images a GPU (graphic processing unit) can render and at the same time the number of images that are being shown on a monitor or screen per second.
Hence, in this case, the correct answer is "Frame Rate"

You have just started a new job as the administrator of the eastsim domain. The manager of the accounting department has overheard his employees joke about how many employees are using "password" as their password. He wants you to configure a more restrictive password policy for employees in the accounting department. Before creating the password policy, you open the Active Directory Users and Computers structure and see the following containers and OU: eastsim Builtin Users Computers Domain Controllers Which steps must you perform to implement the desired password policy? (Select three. Each correct answer is part of the complete solution.)
Explanation:
To implement the desired password policy, you have to carry out these steps
1. An organizational unit, OU has to be created for these employees in east-sim.com
2. Since there is an organizational unit created for the accounting employees, you have to put the employees user objects in this Organizational unit.
3. Then as the administrator the next step that i would take is the configuration of the password policy, then i would link this to the already created organizational unit for these employees

Wesley purchased a word-processing software program. He used it for a year, during which he got regular updates every two months. After a year, he was not allowed to update the software. However, he could continue using it. Why did the updates stop?
Group of answer choices.
A. The software was corrupt and resulted in a bug.
B. He purchased a license with maintenance for a year.
C. The organization discontinued the software.
D. He purchased an open-source license.
E. He purchase a perpetual non-maintenance license.
Answer:
B. He purchased a license with maintenance for a year.
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.
Basically, softwares are categorized into two (2) main categories and these are;
I. Open-source software.
II. Proprietary software.
A proprietary software is also known as a closed-source software and it can be defined as any software application or program that has its source code copyrighted and as such cannot be used, modified or distributed without authorization from the software developer. Thus, it is typically published as a commercial software that may be sold, licensed or leased by the software developer (vendor) to the end users with terms and conditions.
In this scenario, Wesley purchased a word-processing software program. He used it for a year, during which he got regular updates every two months. However, after a year, he was not allowed to update the software but he could continue using it.
This ultimately implies that, Wesley purchased a licensed software with maintenance for a year and as such he would stop receiving an update from the software developer after his subscription expired.
Monster Collector
Write this program using an IDE. Comment and style the code according to the CS 200 Style Guide. Submit the source code files (.java) below. Make sure your source files are encoded in UTF-8. Some strange compiler errors are due to the text encoding not being correct.
Monster collector is a game of chance, where the user tries to collect monsters by guessing the correct numbers between 1 and 5. If the user doesn't guess the incorrect number, you catch the monster, otherwise, it gets away!
Example output:
Welcome to Monster Collector, collect 2 monsters to win!
A wild pikamoo appears! Guess a number between 1 and 5
5
You almost had it, but the monster escaped.
A wild bulbaroar appears! Guess a number between 1 and 5
1
Congratulations, you caught bulbaroar!
There are no more monsters to encounter!
You caught i monsters of 2
Keep training to be the very best!

public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int monsternum, usernum;
int count = 0;
Random rand = new Random();
String [] monsters = {"wild pikamoo","wild bulbaroar"};
for(int i =0;i<2;i++){
monsternum = rand.nextInt(5);
System.out.print("A "+monsters[i]+" appears! Guess a number between 1 and 5: ");
usernum = input.nextInt();
if(monsternum == usernum){ count++; System.out.println("Congratulations, you caught a "+monsters[i]+"!"); }
else{ System.out.println("You almost had it, but the monster escaped."); }
}
System.out.println("There are no more monsters to encounter!");
System.out.println("You caught "+count+" monsters of 2");
if(count!=2){ System.out.print("Keep training to be the very best!"); }
else{ System.out.print("You're the monster collector master!"); }
}
}
Explanation:
This declares monster and user number as integers
int monsternum, usernum;
Initialize count to 0
int count = 0;
Call the random object
Random rand = new Random();
Create a string array to save the monster names
String [] monsters = {"wild pikamoo","wild bulbaroar"};
Iterate for the 2 monsters
for(int i =0;i<2;i++){
Generate a monster number
monsternum = rand.nextInt(5);
Prompt the user to take a guess
System.out.print("A "+monsters[i]+" appears! Guess a number between 1 and 5: ");
Get user guess
usernum = input.nextInt();
If monster number and user guess are equal, congratulate the user and increase count by 1
if(monsternum == usernum){ count++; System.out.println("Congratulations, you caught a "+monsters[i]+"!"); }
If otherwise, prompt the user to keep trying
else{ System.out.println("You almost had it, but the monster escaped."); }
}
Print no monsters again
System.out.println("There are no more monsters to encounter!");
Print number of monsters caught
System.out.println("You caught "+count+" monsters of 2");
Print user score
if(count!=2){ System.out.print("Keep training to be the very best!"); }
else{ System.out.print("You're the monster collector master!"); }

Explanation:
An entrepreneur wants to make an app to show what breeds of dogs are similar to each other. She wants to look at factors such as weight and energy level in her comparison. In the end, she wants each breed of dog to belong to a certain category based on these characteristics. What would be a sensible approach to solving this problem using clustering?
Answer
Dog breeds = observations, Average weight and energy level for each breed = variables. Each cluster is a category.
Explanation:
Using a method of clustering, she would be putting the dog breeds that are more similar together and in order to do this she has to look at various factors such as observation which are the dog breeds, and the average weight and energy level of the breeds, which represents variables. Every one of these clusters would be a category.
Create a program which takes two integers as input from the command line. In your code, allocate space for a 2D array dependent on user input. For example, if they enter 30 40 then your program should allocate space using double **. Once the memory is allocated, initialize the data by setting the value at index (i, j) equal to its position a
Answer:
In C:
#include <stdio.h>
#include <stdlib.h>
int main() {
int r,c;
printf("Row: "); scanf("%d", &r);
printf("Cols: "); scanf("%d", &c);
double *myarr = (int *)malloc(r * c * sizeof(int));
double inputs = 0.0;
for (int rww = 0; rww < r; rww++){
for (int ccl = 0; ccl < c; ccl++){
inputs= inputs+1.0;
*(myarr + rww*ccl + ccl) = inputs; }}
return 0;}
Explanation:
This declares the rows and columns as integers
int r,c;
This gets the number of rows
printf("Row: "); scanf("%d", &r);
This gets the number of columns
printf("Cols: "); scanf("%d", &c);
This dynamically allocate space for array myart
double *myarr = (int *)malloc(r * c * sizeof(int));
This initializes the inputs to the array to 0.0
double inputs = 0.0;
This iterates through the array and initializes each element of the array by its index
for (int rww = 0; rww < r; rww++){
for (int ccl = 0; ccl < c; ccl++){
inputs= inputs+1.0;
*(myarr + rww*ccl + ccl) = inputs; }}

Find the number of ways in which a committee of 4 can be chosen from six boys and
six girls if it must contain at least one boy and one girl.
Answer:
465 ways
Explanation:
Atleast 1 girl and 1 boy
Possible combinations :
1 girl ; 3 boys = 6C1 ; 6C3
2 girls ; 2 boys = 6C2 ; 6C2
3 girls ; 1 boy = 6C3 ; 6C1
(6C1 * 6C3) + (6C2 * 6C2) + (6C3 * 6C1)
Combination formula:
nCr = n! ÷ (n-r)!r!
We can also use a calculator :
6C1 = 6
6C3 = 20
6C2 = 15
Hence,
(6C1 * 6C3) + (6C2 * 6C2) + (6C3 * 6C1)
(6 * 20) + (15 * 15) + (20 * 6)
120 + 225 + 120
= 465 ways

Consider the following code segment.
int a = 0;
int b = 3;
while ((b != 0) && ((a / b) >= 0)
{
a = a + 2;
b = b - 1;
}
What are the values of a and b after the while loop completes its execution?
a = 4, b = 1
a = 0, b = 3
a = 6, b = 0
a = 8, b = -1
Answer:
a=4 , b=1
Explanation:
I'm not a computer science major at all but I think I can help you with this code.
Our program wants us to add 2 to a get new a value while also subtracting 1 from b value to obtain new b value. We we want to for for as long b is not 0 and a/b is nonnegative.
One round we get:
New a=0+2=2
New b=3-1=2
Let's see if we can go another round:
New a=2+2=4
New b=2-1=1
We can't go another round because b would be negative while a is positive which would make a/b negative. So our loop stops at this 2nd round.
a=4 , b=1
Other notes:
2nd choice makes no sense because a is always going to increase because of the addition on a and b was going to decrease because of the subtraction on it.
Third choice makes no sense because a/b doesn't even exist.
Fourth choice a/b is negative not nonnegative.
What is meant by the term text?
A. Printed information only
B. Printed, visual, and audio media
C. Any words conveyed by media
D. Content found only in books and mag
The term text means content found only in books and mag. Thus, option D is correct.
What is a text?
It is a set of statements that allows a coherent and orderly message to be given, either in writing or through the word of a written or printed work. In this sense, it is a structure made up of signs and a certain writing that gives space to a unit with meaning.
A video is a recording of a motion, or television program for playing through a television. A camcorder is a device or gadget that is used to record a video. audio is the sounds that we hear and mix media is a tool used to edit the video.
Digital camcorders are known to have a better resolution. The recorded video in this type of camcorder can be reproduced, unlike using an analog which losing image or audio quality can happen when making a copy. Despite the differences between digital and analog camcorders, both are portable, and are used for capturing and recording videos.
Therefore, The term text means content found only in books and mag. Thus, option D is correct.
