Answer:
The method definition to this question can be defined as follows:
int getPop(char myCode[3])//defining a method getPop that takes char array in its parameter
{
FILE* f = NULL;//defining a pointer variable
int pop;//defining integer variable
char s_code[2];//defining char array state_code
char s_name[100];//defining char array stateName
f = fopen("state", "r");//using pointer variable that use fopen method for open file
if(f == NULL)//defining if block that check file is empty
{
return -1;//return value -1
}
while(!feof(f))//defining while loop for input value in file
{
fscanf(f, "%s %s %d",s_code, s_name, &pop);//input value
if(strncmp(myCode, s_code, 2) == 0)//use if block to compare string value
{
printf("Population for %s: %d", s_name, pop);//print value
return 0;//return 0
}
}
fclose(f);//close file
return 0;
}
Explanation:
In the above code, a method "getPop" is defined that accepts a character array "myCode" in its parameter, and inside the method, one pointer variable "f", one integer variable "pop", and two char array "s_code and s_name" is declared.
In the method firstly fopen method is used that holds a file and use if block to check it is not empty, if the condition is true it will give a value that is "-1".
In the next step, a while loop is declared, that input value and use if block to compare string value, and return 0, and at the last, it closed the file.

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 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;
}
public static GiftBox getNewBox(GiftBox giftBox, double m) {
return new GiftBox(m * giftBox.length, m * giftBox.width, m * giftBox.height);
}
private boolean fitsInside(GiftBox giftBox) {
if(giftBox.length < this.length && giftBox.width <this.width
&& giftBox.height < this.height) {
return true;
}
return false;
}
public static void main(String []args){
GiftBox giftBox = new GiftBox(3.0 , 4.0, 5.0);
GiftBox newGiftBox = getNewBox(giftBox, 0.5);
System.out.println("New Box length: " + newGiftBox.length);
System.out.println("New Box width: " + newGiftBox.width);
System.out.println("New Box height: " + newGiftBox.height);
GiftBox gift = new GiftBox(3.0 , 4.0, 5.0);
GiftBox other = new GiftBox(2.1 , 3.2, 4.3);
GiftBox yetAnother = new GiftBox(2.0 , 5.0, 4.0);
System.out.println(gift.fitsInside(other));
System.out.println(gift.fitsInside(yetAnother));
}

What line of code makes the character pointer studentPointer point to the character variable userStudent?char userStudent = 'S';char* studentPointer;
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 physical host machine has four quad-core CPUs, 16GB of RAM, 1TB of hard drive space, and two 1Gbps NICs. If we need to create four Windows 2008 servers, what will be the first bottleneck we should upgrade?a. CPUb. RAMc. Hard drived. NIC
Answer:
B. Ram
Explanation:
A random access memory (RAM) can be defined as the internal hardware memory which allows data to be read and written (changed) in a computer. Basically, a random access memory (RAM) is used for temporarily storing data such as software programs, operating system (OS), machine code and working data (data in current use) so that they are easily and rapidly accessible to the central processing unit (CPU).
Additionally, RAM is a volatile memory because any data stored in it would be lost or erased once the computer is turned off. Thus, it can only retain data while the computer is turned on and as such is considered to be a short-term memory.
There are two (2) main types of random access memory (RAM) and these are;
1. Static Random Access Memory (SRAM).
2. Dynamic Random Access Memory (DRAM).
Given a physical host machine that has four quad-core central processing units (CPUs), 16GB of random access memory (RAM), 1TB of hard drive space, and two 1Gbps network interface cards (NICs). Therefore, if we need to create four Windows 2008 servers, the first bottleneck we should upgrade is the random access memory (RAM) because it is typically the working memory that would be used by the server to store data, so they can be accessed easily and rapidly by the central processing unit (CPU).
Hence, the random access memory (RAM) may be increased from 16GB to 64GB or more depending on the client's requirements.
A method which applies to the class in which it is declared as a whole and not in response to method calls on a specific object is called a:_______
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.
A static method cannot be overridden or changed. You create a static method for a block of code that is not dependent on instance creation and that can easily be shared by all instances or objects.
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.

Explanation:
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.

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).

The relational algebra expressions can be rearranged and achieve the same result but with a better processing time. A selection on an attribute can be moved from the outside of a query to a selection on just one of the relations being joined (if it isn't an attribute on both relations). Why would this be an improvement?
a. The selection on the joined results would cause a cartesian product operation
b. Moving the selection to the innermost relation keeps the depth of operations that have to be processed more shallow
c. This would reduce the number of tuples to involve in the join resulting in a more efficient query.
d. The outer selection would prevent the optimizer from picking the correct index
Answer:
c. This would reduce the number of tuples to involve in the join resulting in a more efficient query.
Explanation:
SQL or structured query language is a database querying language used to communicate or interact with databases. A database query could be as simple as returning all the columns from a database table to complex like joining several query results which in turn forms an algebra expression.
Every query statement or expression is executed with time, execution time needs to be minimized for efficiency, so, a well-arranged and reduced joining in the query improves the efficiency of the query.

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.
