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'.

Write the code for the method getNewBox. The method getNewBox will return a GiftBox that has dimensions that are m times the dimensions of its GiftBox parameter, where m is a double parameter of the method.
For example, given the following code segment:
GiftBox gift = new Gift Box (3.0, 4.0, 5.0):
The call
getNewBox , 0, 5).
would return a GiftBox whose dimensions are: length = 1.5, width = 2.0, and height = 2.5 .
Answer:
public class GiftBox{
private int length;
private int width;
private int height;
public GiftBox(double length, double width, double height) {
this.length = length;
this.width = width;
this.height = height;

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
A hacker using information gathered from sniffing network traffic uses your banking credentials from a recent transaction to create nearly duplicate bank transfers but alters the target account to steal the funds. The attacker is reproducing traffic to re- create an event from previous transactions. This is an example of what type of attack?
A. Xmas attack
B. Smurf attack
C. DDoS attack
D. Replay attack
Answer: a replay attack, a replay attack is used so that the attacker can go sniff out the hash, and get whatever they are trying to get, then once it goes to the attacker it will go back to the original connection after replaying the hash
Hackers use packet sniffing attacks to intercept or steal potentially unprotected data from networks. A network-generated threat is a sniffing attack, also known as a packet sniffing assault. Thus, option D is correct.
What are the hacker using sniffing network?Snooping gives ethical hackers a lot of information about how a network functions and how its users behave, which can be used to improve a company's cybersecurity.
Sniffing can, however, be utilized by unscrupulous hackers to conduct catastrophic attacks against gullible targets.
A network sniffer can detect someone using excessive bandwidth at a college or commercial organization and hunt them down.
Therefore, replay attacks are employed so that the attacker can find the hash and obtain the desired object. Once the attacker has received the object, the replay attack causes the object to return to the original connection.

Suppose an application generates chunks 60 bytes of data every 200msec. Assume that each chunk gets put into a TCP packet (using a standard header with no options) and that the TCP packet gets put into an IP packets. What is the % of overhead that is added in because of TCP and IP combines?
1) 40%
2) 10%
3) 20%
4) 70%
Answer:
1) 40%
Explanation:
Given the data size = 60 byte
data traversed through TSP then IP
Header size of TCP = 20 bytes to 60 bytes
Header size of IP = 20 bytes to 60 bytes
Calculating overhead:
By default minimum header size is taken into consideration hence TCP header size = 20 bytes and IP header size = 20 bytes
Hence, the correct answer is option 1 = 40%

Answer:
char* studentPointer = &userStudent;
Explanation:
Pointers in C are variables used to point to the location of another variable. To declare pointer, the data type must be specified (same as the variable it is pointing to), followed by an asterisk and then the name of the pointer. The reference of the target variable is also assigned to the pointer to allow direct changes from the pointer variable.
Which of the following is a characteristic of vector graphics?
Answer:
A
Explanation:
Vector graphics consist of mathematical descriptions of shapes as a combination of these numerical vectors. Because the vector graphics define the path that the lines should take, rather than a set of points along the way, they can be used to calculate any number of points, and so can be used at any image resolution.
The characteristics of vector graphics are they are based on mathematical/geometric expression. The correct option is A.
What are vector graphics?Vector graphics are mathematical descriptions of shapes created by combining these numerical vectors. Because vector graphics indicate the course that the lines should travel rather than a set of locations along the way, they may be used to calculate any number of points and thus work at any image resolution.
Raster images generate commonly used image files such as gif, jpeg, jpg, and so on. These can be made with picture editing software such as "Photoshop." Because these work on pixels, when we zoom the image, we can see tiny squares that are nothing more than pixels.
Therefore, the correct option is A, they are based on mathematical/geometric expression.

a. method call
b. an object method
c. private method
d. static method
Answer:
D) Static method
Explanation:
A static method is a method that is created only for the class and not it's instance variables or objects. Such methods can only be accessed by calling them through the class's name because they are not available to any class instance. A static method is created by prefixing the method's name with the keyword static.

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.
Write a Python program to keep track of data for the following information in a medical clinic: doctors, patients, and patient_visits
Patients and Doctors have an ID, first name, and last name as common attributes. Doctors have these additional attributes: specialty (e.g. heart surgeon, ear-nose-throat specialist, or dermatologist), total hours worked, and hourly pay. Further, doctors keep track of the patient_visits. A patient_visit has the following attributes, number_of_visits to the clinic, the patient who is visiting, the doctor requested to be visited, and the number of hours needed for consultation. Based on the number of consultation hours, the doctor will get paid.
The following functions are required:
1. addVisit: this function adds a patient_visit to the doctor. A new visit will NOT be added if the doctor has already completed 40 hours or more of consultation. If this happens, an error is thrown mentioning that the doctor cannot have more visits this week.
2. calculatePay: this function calculates the payment for the doctor using the following logic: Each hour is worth AED 150 for the first two visits of the patient and all further visits are billed at AED 50.
3. calculateBill: this function calculates the bill for the patient, which displays the doctor's details, patient details, and payment details. An additional 5% of the total is added as VAT.
The student is required to identify classes, related attributes, and behaviors. Students are free to add as many attributes as required. The appropriate access modifiers (private, public, or protected) must be used while implementing class relationships. Proper documentation of code is mandatory. The student must also test the code, by creating at-least three objects. All classes must have a display function, and the program must have the functionality to print the current state of the objects.

Chegg Suppose the heap is a full tree, size 2^n-1. what is the minimum number of steps to change a min heap to a max heap. Show your logic.
Answer:
Explanation:
We start from the bottom-most and rightmost internal node of min Heap and then heapify all internal modes in the bottom-up way to build the Max heap.
To build a heap, the following algorithm is implemented for any input array.
BUILD-HEAP(A)
heapsize := size(A)
for i := floor(heapsize/2) downto 1
do HEAPIFY(A, i)
end for
Convert the given array of elements into an almost complete binary tree.
Ensure that the tree is a max heap.
Check that every non-leaf node contains a greater or equal value element than its child nodes.
If there exists any node that does not satisfy the ordering property of max heap, swap the elements.
Start checking from a non-leaf node with the highest index (bottom to top and right to left).

It should be noted that the purpose of black-box testing is to isolate the behavior of a given component of software.
The Bellman-Ford algorithm for the shortest path problem with negative edge weights will report that there exists a negative cycle if at least one edge can still be relaxed after performing nm times of relaxations. The algorithm, however, does not specify which cycle is a negative cycle. Design an algorithm to report one such cycle if it exists. You should make your algorithm runs as fast as possible.
Answer:
- Iterate over the Bellman-Ford algorithm n-1 time while tracking the parent vertex and store in an array.
- Do another iteration and if no relaxation of the edges occurs in the nth iteration then print of return "There are no negative cycle".
- Else, store the vertex of the relaxed edge at the nth iteration with a variable name.
- Then iterate over the vertexes starting from the store vertex until a cycle is found then print it out as the cycle of negative weight.
Explanation:
The Bellman-Ford algorithm can be used to detect a negative cycle in a graph. The program should iterate over the algorithm, in search of a relaxed edge. If any, the vertex of the specified edge is used as a starting point to get the target negative cycle.
