Explanation:
The class DrawingPanel is a Java class that gets the user input for the coordinate of a path with predetermined heigth and width (defined in the class). The methods of the class are; getGraphics(), getBounds(), getBackground(), setColor() and fillRect(). The result is a rectangular path GUI on the screen.
C++ please
Write a program that does the following.
Create a dynamic two dimensional squarearray of unsigned integers (array_one). Prompt the user to enter the number of rows and columns they want (maximum of 30) (rows and columns must be the same for a square array)
Pass the array to a function that will initialize the two dimensional array to random numbers between 0 and 4000 using the rand() library function. Here is the kicker: The array cannot have any repeated values!
Create another dynamic two dimensional array of the same size (array_transpose)
Pass both arrays to a function that will generate the transpose of array_one returning the values in array_transpose. (If you don’t already know the transpose swaps the rows and columns of an array.) Example: Suppose you have a 4 x 4 array of numbers (array_one). The transpose is shown below (array_transpose)
Array One Array Transpose
1 2 3 4 1 5 9 13
5 6 7 8 2 6 10 14
9 10 11 12 3 7 11 15
13 14 15 16 4 8 12 16
Pass each array to a print_array function that will print (to the screen or a file) the results of a test case with a 20 by 20 array.
Answer:
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main(){
int n;
cout<< "Enter the row and column length: ";
cin>> n;
int array_one[n][n];
int array_transpose[n][n];
for (int i = 0; i < n; i++){
for (int j= 0; j < n; j++){
srand((unsigned) time(0));
array_one[i][j] = (rand() % 4000)
array_transpose[j][i] = array_one[i][j];
}
}
}
Explanation:
The C source code has three variables, 'array_one', array_transpose' (both of which are square 2-dimensional arrays), and 'n' which is the row and column length.
The program loops n time for each nth number of the n size to assign value to the two-dimensional array_one. the assign values to the array_transpose, reverse the 'i' and 'j' values to the two for statements for array_one to 'j' and 'i'.

If an object someThing has a method someMethod( ), then you can call the method using the statement ____________ .
a. someMethod(someThing);
b. someThing.someMethod( );
c. someMethod.someThing() ;
d. someThing = someMethod( );
Answer:
C) someThing.someMethod( )
Explanation:
The methods in a class can be accessed outside the class (assuming they are public methods and not private to the class) by using the dot(.) symbol and calling the method on the instance or object of the class.
In this case, the object of the class someThing, calls the method, someMethod( ) by using a dot and the name of the method with a parentheses at the end. This enables the code in the method act on the class instance or object.

Write a program that asks the user for a word. Next, open up the movie reviews.txt file and examine every review one at a time. If a review contains the desired word you should make a note of the review score in an accumulator variable. Finally, produce some output that tells your user how that word was used across all reviews as well as the classification for this word (any score of 2.0 or higher can be considered
Answer:
import numpy as np
word = input("Enter a word: ")
acc = []
with open("Downloads/record-collection.txt", "r") as file:
lines = file.readlines()
for line in lines:
if word in line:
line = line.strip()
acc.append(int(line[0]))
if np.mean(acc) >= 2:
print(f"The word {word} is a positive word")
print(f"{word} appeared {len(acc)} times")
print(f"the review of the word {word} is {round(np.mean(acc), 2)}")
else:
print(f"the word {word} is a negative word with review\
{round(np.mean(acc), 2)}")
Explanation:
The python program gets the text from the review file, using the user input word to get the definition of reviews based on the word, whether positive or negative.
The program uses the 'with' keyword to open the file and created the acc variable to hold the reviews gotten. The mean of the acc is calculated with the numpy mean method and if the mean is equal to or greater than 2 it is a positive word, else negative.

Which important aspect of the Roman Empire did the barbarians destroy?
Answer:
centers of learning
Explanation:
Under the leadership of Emperor Valens, Rome was already having financial hardships. This meant that it didn't have enough money left to repair its empire nor to strengthen it against invaders. Soon, the barbarians such as the Franks, Huns, Saxons, etc. started attacking Rome. They spent a lot of time destroying the outer regions of the empire because they were also at war with each other. They penetrated Rome and it soon fell. The barbarians didn't only destroy the cities but they also destroyed the "centers of learning." Roman people were known to value education. With the fall of the Roman Empire, so did education and sophisticated architectures follow.

A strictly dominates choice B in a multi-attribute utility. It is in your best interest to choose A no matter which attribute youare optimizing.
a. True
b. False
Answer:
A strictly dominates choice B in a multi-attribute utility. It is in your best interest to choose A no matter which attribute youare optimizing.
a. True
Explanation:
Yes. It is in the best interest to choose option A which dominates choice B. A Multiple Attribute Utility involves evaluating the values of alternatives in order to make preference decisions over the available alternatives. Multiple Attribute Utility decisions are basically characterized by multiple and conflicting attributes. To solve the decision problem, weights are assigned to each attribute. These weights are then used to determine the option that should be prioritized.
Why are people's visions of utopias and dystopias subjective?
A. Because the vision one person has of paradise will likely match
the vision most people have of a utopia
B. Because only certain technologies make things better and
different ones make things worse in a dystopia
C. Because all technology is dangerous and can lead to the downfall
of all societies, resulting in dystopia
D. Because the technology needed for one person's utopia may be
what creates disaster for another person's dystopia
Answer:
D. Because the technology needed for one person's utopia may be what creates disaster for another person's dystopia.
Explanation:
Because the technology needed for one person's utopia may be what creates disaster for another person's dystopia are people's visions of utopias and dystopias subjective. Thus option D is correct.
What are utopias and dystopias?Speculative fiction categories that study social as well as political structures include utopian and dystopian literature. In order to pique readers' interest, utopian fiction often depicts a world that adheres to the author's ethics and has many elements of a different reality.
Ultimately, it all varies depending on who you ask. A person's dystopia may be another person's utopia. We don't all have the same notions regarding what a utopia would look like, which is, in my opinion, one of the grounds why people don't live in one. Therefore, option D is the correct option.

Problem 4 (25 points)Consider a byte addressing architecture with 64-bit memory addresses.(a)Which bits of the address would be used in the tag, index and offset in a direct-mapped cache with 512 1-word blocks. 3(b)Which bits of the address would be used in the tag, index and offset in a direct-mapped cache with 64 8-word blocks.(c)What is the ratio of bits used for storing data to total bits stored in the cache in each of the above cases
Answer:
Following are the solution to the given points:
Explanation:
The Memory address value = 64 bit
The Size of the word [tex]= \frac{64}{8} =8 \ Byte[/tex]
In point a:
The offset size [tex]= 3\ bits[/tex] ( in 1-word block size)
The Index size [tex]= 9 \ bits[/tex] (as block number =512)
Tag size [tex]= 64 - 12 = 52\ bits[/tex]
In point b:
The offset size [tex]= 8 \times 8 \ bytes = 2^6 = 6 \ bits.[/tex]
The Index size [tex]= 64 \ bits = 2^6 \ =6 \ bits[/tex]
Tag size [tex]= 64 - 12 = 52\ bits[/tex]
In point c:
The Ratio at point a
[tex]\to 3:64[/tex]
The Ratio at point b
[tex]\to 6:64[/tex]

Suppose that a t-shirt comes in five sizes: S, M, L, XL, XXL. Each size comes in four colors. How many possible t-shirts are there?
Answer:
120
Explanation:
This question is basically asking how many ways can we arrange 5 sizes of shirts if they come in 4 colors.
5 permutation of 4
To find permutation, we use the formula
P(n, r) = n! / (n - r)!
Where
n is the size of the shirts available, 5
r is the color of each shirt available, 4
P(5, 4) = 5! / (5 - 4)!
P(5, 4) = (5 * 4 * 3 * 2 * 1) / 1!
P(5, 4) = 120 / 1
P(5, 4) = 120
Therefore, the total number of shirts available is 120
