What is the difference between a worm and a typical virus?
A) Worms are a type of spyware; viruses are a type of malware.
B) Worms are impossible to remove; viruses can be tracked and removed.
C) Worms are stronger than viruses; viruses are stronger than spam.
D) Worms travel independently of human action; viruses require human actions.
Answer:
Option C
Explanation:
Option A is incorrect as Worm is a form of malware
Option B is incorrect because antivirus can remove all forms of malware
Option C is correct because a worm is more problematic as compared to the virus. Also, viruses are weaker than worm because they need a host file to run but a worm can work independently.
Option D is also incorrect because both are able to self replicate.
Requirements description:
Assume you work part-time at a Cafe. As the only employee who knows java programming, you help to write an ordering application for the store.
The following is a brief requirement description with some sample output.
1. Selecting Breakfast or Lunch(5 points)
When the program starts, it first shows option Breakfast or Lunch. A sample output is as follows.
=== Select Breakfast or Lunch: ===
1. Breakfast
2. Lunch
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 2, the user will see an error message.
A sample output for invalid number is as follows.
Select Breakfast or Lunch [1, 2]: 0
Error! Number must be greater than 0.
Select Breakfast or Lunch [1, 2]:
2. Selecting Coffee (20 points)
When the program continues, it shows a list/menu of coffee and their prices, then asks a user to select a coffee by entering an integer number. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select a coffee [1, 5]:
You are supposed to validate the input.
If the user enters a letter or a number not between 1 and 5, the user will see an error message.
A sample output for invalid number is as follows.
Select a coffee [1, 5]: 0
Error! Number must be greater than 0.
Select a coffee [1, 5]:
In your program, you can hard-code the information for coffee (i.e., coffee names and prices) shown above, such as "1 Espresso $3.50" and use the hard-code price, such as 3.50, for calculation of a total price of the order.
After the user makes a choice for coffe, such as 2 for Latte. The program continues asking for selecting a coffee so that the user can have multiple coffee orders. The user can enter "5" to quit coffee selection. A sample output is as follows.
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 2
=== Select Coffee: ===
1 Espresso $3.50
2 Latte $3.50
3 Cappuccino $5.00
4 Cold Brew $3.00
5 Quit Coffee selection
Select Coffee: [1, 5]: 5
3. Selecting Food (10 points)
After Coffee selection, the program shows food selection. A sample output is as follows.
=== Select Food: ===
1 Tuna Sandwich $10.00
2 Chicken Sandwich $10.00
3 Burrito $12.00
4 Yogurt Bowl $8.00
5 Avocado Toast $8.00
6 Quit Food selection
Select Food: [1, 6]: 1
Input validation is needed and works as before. Like Coffee selection which allows selecting multiple Coffee orders, food selection also repeats after the user enters a valid number between 1 and 5.
You hard-code the information for food shown above, such as "1 Tuna Sandwich $10.00" and use the hard-code price, such as 10.00, for calculation of the total price of the order.
Answer:
The code has been written in Java.
The source code of the file has been attached to this response. The source code contains comments explaining important lines of the program.
A sample output got from a run of the application has also been attached.
To interact with the program, kindly copy the code into your Java IDE and save as Cafe.java and then run the program.

Explanation:
The project downloaded contains a package (folder) named Q1 within the src folder. Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val
You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop
0.3, 0.7,0.2, 0.6,0.9
then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration).
If
0.6, 0.8, 0.75
was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration).
These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows.
a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1
b. Add a loop around the code created in Part a that continues until counter equals 3.
c. Use the variable numlterations to count how many times your loop iterates.

Rideshare companies like Uber or Lyft track the x,y coordinates of drivers and customers on a map. If a customer requests a ride, the company's app estimates the minutes until the nearest driver can arrive. Write a method that, given the x and y coordinates of a customer and the three nearest drivers, returns the estimated pickup time. Assume drivers can only drive in the x or y directions (not diagonal), and each mile takes 3.5 minutes to drive. All values are doubles; the coordinates of the user and of the drivers are stored as arrays of length 2. 289222.1780078.qx3zqy7
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main (String[]args){
Scanner input = new Scanner(System.in);
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
System.out.print("Enter user coordinates: ");
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
System.out.print("Enter driver 1 coordinates: ");
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
System.out.print("Enter driver 2 coordinates: ");
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
System.out.print("Enter driver 3 coordinates: ");
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");
}
}
Explanation:
The following array declarations are for the customer and the three drivers
double user[] = new double[2]; double dr1[] = new double[2];
double dr2[] = new double[2]; double dr3[] = new double[2];
This prompts the user for the customer's coordinates
System.out.print("Enter user coordinates: ");
This gets the customer's coordinate
for(int i =0;i<2;i++){ user[i] = input.nextDouble(); }
This prompts the user for the driver 1 coordinates
System.out.print("Enter driver 1 coordinates: ");
This gets the driver 1's coordinate
for(int i =0;i<2;i++){ dr1[i] = input.nextDouble(); }
This prompts the user for the driver 2 coordinates
System.out.print("Enter driver 2 coordinates: ");
This gets the driver 2's coordinate
for(int i =0;i<2;i++){ dr2[i] = input.nextDouble(); }
This prompts the user for the driver 3 coordinates
System.out.print("Enter driver 3 coordinates: ");
This gets the driver 3's coordinate
for(int i =0;i<2;i++){ dr3[i] = input.nextDouble(); }
This calculates the distance between driver 1 and the customer
double dr1dist = Math.abs(user[0] - dr1[0]) + Math.abs(user[1] - dr1[1]);
This calculates the distance between driver 2 and the customer
double dr2dist = Math.abs(user[0] - dr2[0]) + Math.abs(user[1] - dr2[1]);
This calculates the distance between driver 3 and the customer
double dr3dist = Math.abs(user[0] - dr3[0]) + Math.abs(user[1] - dr3[1]);
The following print statements print the estimated pickup time of each driver
System.out.println("Estimated pickup time of driver 1 "+(3.5 * dr1dist)+" minutes");
System.out.println("Estimated pickup time of driver 2 "+(3.5 * dr2dist)+" minutes");
System.out.println("Estimated pickup time of driver 3 "+(3.5 * dr3dist)+" minutes");

Complete the Rectangle class. It has a rectangle's length and width as class variables and contains methods to compute its area and perimeter. If either parameter is negative, the method should calculate based on its absolute value. Then, you'll take user inputs to create an instance of Rectangle. For example, if you provide the input -13 7 You should receive the output Perimeter = 40.0 Area = 91.0 Note: It is NOT necessary to use the math module to calculate absolute value, though you may if you want. 298800.1775650.qx3zqy7 LAB ACTIVITY 28.4.1: Final Exam 2021 - Problem 4 of 6 0/10 main.py Load default template... 1 class Rectangle: _init__(self, length, width): # your code here 4 5 def area (self): 6 # your code here 7 8 def perimeter (self): 9 # your code here 10 11 if _name__ == '__main__': 12 1 = float(input) 13 w = float(input) 14 r = Rectangle(1, w) 15 print("Perimeter =', r.perimeter()) 16 print('Area =', r.area(), end='')|
Answer:
The complete program is as follows:
class Rectangle:
def __init__(self, length, width):
self.width = abs(width)
self.length = abs(length)
def area(self):
area = self.length * self.width
return area
def perimeter (self):

if __name__ == '__main__':
l = float(input(": "))
w = float(input(": "))
r = Rectangle(l, w)
print('Perimeter =', r.perimeter())
print('Area =', r.area(), end='')
Explanation:
This defines the class:
class Rectangle:
This gets the parameters from maiin
def __init__(self, length, width):
This sets the width
self.width = abs(width)
This sets the length
self.length = abs(length)
The area function begins here
def area(self):
Calculate the area
area = self.length * self.width
Return the calculated area back to main
return area
The perimeter function begins here
def perimeter (self):
Calculate the perimeter
perimeter = 2 * (self.length + self.width)
Return the calculated perimeter back to main
return perimeter
The main begins here
if __name__ == '__main__':
This gets input for length
l = float(input(": "))
This gets input for width
w = float(input(": "))
This passes the inputs to the class
r = Rectangle(l, w)
This prints the returned value for perimeter
print('Perimeter =', r.perimeter())
This prints the returned value for area
print('Area =', r.area(), end='')

Suppose that a minus sign in the input indicates pop the stack and write the return value to standard output, and any other string indicates push the string onto the stack. Further suppose that following input is processed:
this parrot - wouldn't voom - if i put -- four thousand --- volts - through it -
What are the contents (top to bottom) left on the stack?
a. through wouldn't this.
b. this wouldn't through.
c. it through wouldn't.
d. it through volta.
e. volts through it.
Answer:
e. volts through it
Explanation:
volts through it
The contents (top to bottom) left on the stack is volts through it. Thus, option E is correct.
What is standard output?When a computer program begins execution, standard streams are interconnected input and output channels of communication between the program and its surroundings. The three I/O connections are known as standard input (stdin), standard output (stdout), and standard error (stderr).
A negative sign in the input indicates that the stack should be popped, and the return value should be sent to standard output, whereas any other string means that the string should be pushed into the stack. Assume that the following input is processed: this parrot would not voom if I pushed — four thousand —- volts - through it.
The contents of the stack (from top to bottom) are volts via it. As a result, option E is correct.
