Answer:
Following are the responses to this question:
Explanation:
The computer system's memory hierarchy arranges space through tiny, fast, costly stocks only at top of the pyramid and complements them through big, lighter, cheap storage facilities at every representation made. It is needed to limit the time for data access for application executes. A very design of the main memory allows a system to have easy access to the information and instructions necessary to execution time. A traditional technique of system memory works like:
[tex]Level\ 0 (Top Level) \to CPU \ Registers\\\\Level \ 1 \to Cache\ Memory \ (SRAMs)\\\\Level\ 2 \to Main \ Memory \ (DRAMs)\\\\Level \ 3 \to Magnetic \ Disk\ (Disk \ Storage)\\\\Level \ 4 \to Optical \ Disk\\\\Level \ 5 \to Magnetic\ Tape\\\\[/tex]
Because as memory cost rises below level 5 to level 0. CPU registers become costly as the cache memory, which then, in turn, is much more costly than for the memory.
Whenever the access time of CPU registries becomes reduced from level 5 to level 0, its time complexity between reading/write transactions is much more swift than Cache Memory Access period which in turn is quicker than that of the main memory Communication cost and so forth.
So, we need a memory hierarchy to analyze the information (read/write requests) efficiently, in turn for all the top-level to read the information more quickly and thoroughly. Therefore, the architecture of the computer program's Main memory enables a system to provide secure access to information and guidance for running programs.

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:

Subtraction + Decision and Loop
This is a twist on the previous exercise that will help you review loops and decision structures. You will again ask the user to enter two numbers. However, you will ALWAYS subtract the smaller number from the larger number to ensure that you never get a negative number for an answer. You do this by checking the numbers and switching them if they are not in the right order (larger then smaller). All of this checking, switching, subtracting, and output of the answer should occur in a function.
((( THIS WAS THE PREVIOUS EXERCISE
Function Basics - Arguments and Parameters
This is another easy exercise to test your knowledge of the fundamentals. In main(), ask the user to enter two integers. Pass those two integers to a function that will subtract one number from another. This function must also output the answer to the user.
Output:
Enter two integers (separated by a space) and this program will subtract them: [user enters: 5 7]
5 - 7 = -2
Notes and Hints:
1) From now on, you must use a function prototype for all programs that use functions. Don't expect me to ask for it in each exercise. )))
Finally, ask the user if they would like to run the program again. By now, you should know exactly what type of loop to use.
Output:
Enter two integers (separated by a space) and this program will subtract the smaller from the larger: [user enters: 7 5]
7 - 5 = 2
Do you want to run this program again? [user enters: y]
Enter two integers (separated by a space) and this program will subtract the smaller from the larger: [user enters: 5 7]
7 - 5 = 2
Do you want to run this program again? [user enters: n]
Notes and Hints:
1) As always, make sure you accept an upper or lower case 'Y'
Answer:
In Python:
def subsmall(num1,num2):
if num1 > num2:
return num1 - num2
else:
return num2 - num1
repeat = True
while(repeat):
num = input("Enter two integers: ")
nums = num.split(" ")
print(subsmall(int(nums[0]),int(nums[1])))
runagain = input("Run program again? ").lower()
if runagain == "y":
repeat=True
else:
repeat = False
Explanation:
The function begins here
def subsmall(num1,num2):
This subtracts num2 from num1 if num2 is smaller
if num1 > num2:
return num1 - num2
If otherwise, subtract num1 from num2
else:
return num2 - num1
The main begins here
This initialiazes a boolean variable to true
repeat = True
This loop is repeated until the boolean variable is false
while(repeat):
Prompt to enter two integers
num = input("Enter two integers: ")
Split the string by space
nums = num.split(" ")
This passes the two integers to the function and also prints the differences
print(subsmall(int(nums[0]),int(nums[1])))
Prompt to run the program again
runagain = input("Run program again? ").lower()
If input is Y or y, the loop repeats
if runagain == "y":
repeat=True
The program ends if otherwise
else:
repeat = False

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; }}

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!"); }

Initially: [tex]a = 0[/tex] and [tex]b = 1[/tex]
The iteration is repeated 5 times and the calculation is as follows:
First iteration:
[tex]c = a + b =0 + 1 = 1[/tex]:=> [tex]c = 1[/tex]
[tex]a = b[/tex]:=> [tex]a= 1[/tex]
[tex]b = c[/tex]:=>[tex]b = 1[/tex]
Second iteration:
[tex]c = a + b =1 + 1 = 2[/tex]:=> [tex]c = 2[/tex]
[tex]a = b[/tex]:=> [tex]a= 1[/tex]
[tex]b = c[/tex]:=>[tex]b = 2[/tex]
Third iteration:
[tex]c = a + b =1 + 2= 3[/tex]:=> [tex]c = 3[/tex]
[tex]a = b[/tex]:=> [tex]a= 2[/tex]
[tex]b = c[/tex]:=>[tex]b = 3[/tex]
Fourth iteration:
[tex]c = a + b =2 + 3= 5[/tex]:=> [tex]c = 5[/tex]
[tex]a = b[/tex]:=> [tex]a= 3[/tex]
[tex]b = c[/tex]:=>[tex]b = 5[/tex]
Fifth iteration:
[tex]c = a + b =3 + 5= 8[/tex]:=> [tex]c = 8[/tex]
[tex]a = b[/tex]:=> [tex]a= 5[/tex]
[tex]b = c[/tex]:=>[tex]b = 8[/tex]
End of iteration
document. write(c) prints the value of c which is 8

This program reads a file called 'test.txt'. You are required to write two functions that build a wordlist out of all of the words found in the file and print all of the unique words found in the file. Remove punctuations using 'string.punctuation' and 'strip()' before adding words to the wordlist.
Write a function build_wordlist() that takes a 'file pointer' as an argument and reads the contents, builds the wordlist after removing punctuations, and then returns the wordlist. Another function find_unique() will take this wordlist as a parameter and return another wordlist comprising of all unique words found in the wordlist.
Example:
Contents of 'test.txt':
test file
another line in the test file
Output:
['another', 'file', 'in', 'line', 'test', 'the']

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.

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.
