Compute change
A cashier distributes change using the maximum number of five dollar bills, followed by one dollar bills. For example, 19 yields 3 fives and 4 ones. Write a single statement that assigns the number of one dollar bills to variable numOnes, given amountToChange. Hint: Use the % operator.
import java.util.Scanner;
public class ComputingChange {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int amountToChange;
int numFives;
int numOnes;
amountToChange = scnr.nextInt();
numFives = amountToChange / 5;
/* Your solution goes here */
System.out.print("numFives: ");
System.out.println(numFives);
System.out.print("numOnes: ");
System.out.println(numOnes);
}
}
Answer:
Explanation:
The following code is written in Java and modified to do as requested. It asks the user to enter a number that is saved to the amountToChange and then uses the % operator to calculate the number of 5 dollar bills and the number of 1 dollar bills to give back. A test case has been provided and the output can be seen in the attached image below.
import java.util.Scanner;
class ComputingChange {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int amountToChange;
int numFives;
int numOnes;
amountToChange = scnr.nextInt();
numFives = amountToChange / 5;
/* Your solution goes here */
numOnes = amountToChange % 5;
System.out.print("numFives: ");
System.out.println(numFives);
System.out.print("numOnes: ");
System.out.println(numOnes);
}

Switched Ethernet, similar to shared Ethernet, must incorporate CSMA/CD to handle data collisions. True False
Answer:
False
Explanation:
The Carrier-sense multiple access with collision detection (CSMA/CD) technology was used in pioneer Ethernet to allow for local area networking. Carrier-sensing aids transmission while the collision detection feature recognizes interfering transmissions from other stations and signals a jam. This means that transmission of the frame must temporarily stop until the interfering signal is abated.
The advent of Ethernet Switches resulted in a displacement of the CSMA/CD functionality.

Create and configure databases in oracle database management system operation administration
Answer:
You typically create a database during Oracle Database software installation. However, you can also create a database after installation.
Reasons to create a database after installation are as follows:
You used Oracle Universal Installer (OUI) to install software only, and did not create a database. You want to create another database (and database instance) on the same host computer as an existing Oracle database. In this case, this chapter assumes that the new database uses the same Oracle home as the existing database. You can also create the database in a new Oracle home by running OUI again. You want to make a copy of (clone) a database.

In the early 1900s, military moved their resources to distant locations with the help of
Answer:
In the early 1900s, military moved their resources to distant locations with the help of trains, ships, and, to a lesser extent, horse-drawn wagons. This was so because at that time airplanes did not yet exist, capable of transporting inputs to any part of the world in a very short period of time. Therefore, inputs and resources were brought by sea and, if impossible, through land, using railways or highways.

Carl is planning for a large advertising campaign his company will unveil. He is concerned that his current e-commerce server farm hosted in a public cloud will be overwhelmed and suffer performance problems. He is researching options to dynamically add capacity to the web server farm to handle the anticipated additional workload. You are brought in to consult with him on his options. What can you recommend as possible solutions
Answer:
Cloud Bursting
Explanation:
One of the best possible solutions for this scenario would be Cloud Bursting. This is a solution of using Cloud Server services to handle the server farm workload. The difference is that Cloud Bursting allows the company to use the Cloud services only when their own personal web server farms hit peak demand and can no longer handle the incoming demand. The excess demand is outsourced to the Cloud Server and lets them handle it dynamically without the company having to add any additional hardware to their server farm.

Which attack form either exploits a software flaw or floods a system with traffic in order to prevent legitimate activities or transactions from occurring?
Answer:
Denial of service attack.
Explanation:
In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.
This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, sniffing, DOS attack, etc.
A denial of service (DOS) attack is a form of cyber attack that involves either the exploitation of a software flaw or overwhelmingly floods a computer system in a network with traffic in order to prevent authorized users from performing legitimate activities or transactions.
Some of the ways to prevent vulnerability or cyber attacks in a network are;
1. Ensure you use a very strong password with complexity through the use of alphanumerics.
2. You should use a two-way authentication service.
3. You should use encrypting software applications or services.

This means that the surface area is composed of the base area (i.e., the area of bottom square) plus the side area (i.e., the sum of the areas of all four triangles). You are given the following incomplete code to calculate and print out the total surface area of a square pyramid: linclude > h: base azea- calcBasekrea (a) : cout << "Base auxface area of the squaze pyzamid is" << base area << "square feet."< endi: // add your funetion call to calculate the side ares and assign // the zesult to side area, and then print the result //hdd your function call to print the total surface area return 0F float calcBaseArea (float a) return pou (a, 2) /I add your function definicion for calcSideärea here // add your function definition tor prntSurfârea here This code prompts for, and reads in the side length of the base (a) and height of a square pyramid (h) in feet, and then calculates the surface area. The function prototype (i.e. function declaration), function definition, and function call to calculate and print the base area has already been completed for you. In the above program, a and h are declared in the main function and are local to main. Since a is a local variable, notice how the length a must be passed to calcBaseArea to make this calculation. One of your tasks is to add a new function called calesidearea that computes and returns the side area of the square pyramid. Given that the formula uses both the length a and height h of the square pyramid, you must pass these two local variables to this function. You will assign the returned value of this function to side area and then print the value to the terminal. Refer to what was done for calcBaseArea when adding your code. Your other task is to add a new function called prntsprfArea that accepts the base area and side area values (i.e, these are the parameters) and prints out the total surface area of the square pyramid inside this function. Since this function does not return a value to the calling function, the return type of this function should be void Now, modify the above program, referring to the comments included in the code.

Answer:
Chernoff faces.
Explanation:
Chernoff faces is a data visualization technique that was developed by a statistician named Herman Chernoff. He introduced this data visualization technique to the world in 1973 to represent multivariate or multidimensional data containing at least eighteen (18) variables.
In Chernoff faces, each attribute is associated with a specific feature of a face (nose, eyes, ears, hair, mouth, and eyebrows), and the attribute value with respect to size, shape, orientation, colour and placement is used to determine the way a facial feature is expressed.
The Chernoff face is a technique designed and developed to help detect similarities between different items and discern subtle changes in facial expressions from the perspective of an observer.

Assign courseStudent's name with Smith, age with 20, and ID with 9999. Use the print member function and a separate cout statement to output courseStudents's data. End with a newline. Sample output from the given program:
#include
#include
using namespace std;
class PersonData {
public:
void SetName(string userName) {
lastName = userName;
};
void SetAge(int numYears) {
ageYears = numYears;
};
// Other parts omitted
void PrintAll() {
cout << "Name: " << lastName;
cout << ", Age: " << ageYears;
};
private:
int ageYears;
string lastName;
};
class StudentData: public PersonData {
public:
void SetID(int studentId) {
idNum = studentId;
};
int GetID() {
return idNum;
};
private:
int idNum;
};
int main() {
StudentData courseStudent;
/* Your solution goes here */
return 0;
}
Answer:
Replace /* Your solution goes here */
with the following:
courseStudent.SetName("Smith");
courseStudent.SetAge(20);
courseStudent.SetID(9999);
courseStudent.PrintAll();
cout <<courseStudent.GetID();
Explanation:
From the given code segment, we have the following methods defined under the StudentData class;
SetName -> It receives name from the main
SetAge -> It receives age from the main
SetID --> It receives ID from the main and passes it to GetID method
printID --> Prints all the required output.
So, we have:
Pass name to setName
courseStudent.SetName("Smith");
Pass age to setAge
courseStudent.SetAge(20);
Pass ID to setID
courseStudent.SetID(9999);
Print all necessary outputs
courseStudent.PrintAll();
Manually print the student ID
cout <<courseStudent.GetID();

#include <numeric>//defining header file
using namespace std;
int main()//main method
{
vector<int> countDown(0);//defing an integer array variable countDown
int newSize = 0;//defing an integer variable newSize that holds a value 0
int i = 0;//defing an integer variable i that initialize with 0
newSize = 3;// //use newSize to hold a value
countDown.resize(newSize,0);// calling the resize method that accepts two parameters
for (i = 0; i < newSize; ++i)//defining a loop that reverse the integer value
{
countDown[i] = newSize -i;//reverse the value and store it into countDown array
cout << countDown.at(i) << " ";//print reverse array value
}
cout << "Go!" << endl;//print message
return 0;
}
Output:
3 2 1 Go!
Explanation:
In the given code inside the main method an integer array "countDown" and two integer variables "newSize and i" is declared that initializes a value that is 0.
In the next step, an array is used that calls the resize method that accepts two parameters, and define a for a loop.
In this loop, the array is used to reverse the value and print its value with the message.
