Answer:
The modified program in Python is as follows:
import math
paint_colors = {'red': 35,'blue': 25,'green': 23}
wall_height = int(input('Enter wall height (feet):\n'))
wall_width = int(input('Enter wall width (feet):\n'))
area = wall_height*wall_width
print('Wall area:',area,'square feet')
paint_needed = area/350.0
print('Paint needed: {:.2f} gallons'.format(paint_needed))
print('Cans needed:',round(paint_needed),'can(s)')
color = input("Choose a color to paint the wall: ")
print("Cost of purchasing", color, "paint: $",paint_colors[color])
Explanation:
The italicized are given from the question [unchanged]
import math
paint_colors = {'red': 35,'blue': 25,'green': 23}
wall_height = int(input('Enter wall height (feet):\n'))
This gets input for width
wall_width = int(input('Enter wall width (feet):\n'))
Calculate the wall area
area = wall_height*wall_width
Print the calculated wall area
print('Wall area:',area,'square feet')
Calculate the amount of paint needed
paint_needed = area/350.0
Print the amount of paint needed to 2 decimal places
print('Paint needed: {:.2f} gallons'.format(paint_needed))
Print the amount of can needed to nearest integer
print('Cans needed:',round(paint_needed),'can(s)')
Prompt user for color of paint [here, we assume the user input is correct]
color = input("Choose a color to paint the wall: ")
Prints the corresponding amount for the color
print("Cost of purchasing", color, "paint: $",paint_colors[color])

Given that n refers to a positive int use a while loop to compute the sum of the cubes of the first n counting numbers, and associate this value with total. Use no variables other than n, k, and total in python
Answer:
The program in Python is as follows:
n = int(input("n:"))
total = 0
for k in range(1,n+1):
total+=k**3
print(total)
Explanation:
This gets input for n
n = int(input("n:"))
This initializes total to 0
total = 0
This iterates from 1 to n
for k in range(1,n+1):
This adds up the cube of each digit
total+=k**3
This prints the calculated total
print(total)
Write a C class, Flower, that has three member variables of type string, int, and float, which respectively represent the name of the flower, its number of pedals, and price. Your class must include a constructor method that initializes each variable to an appropriate value, and your class should include functions for setting the value of each type, and getting the value of each type.
Answer and Explanation:
C is a low level language and does not have classes. The language isn't based on object oriented programming(OOP) but is actually a foundation for higher level languages that adopt OOP like c++. Using c++ programming language we can implement the class, flower, with its three variables/properties and functions/methods since it is an object oriented programming language.
Consider the following class definitions.
public class Apple
{
public void printColor()
{
System.out.print("Red");
}
}
public class GrannySmith extends Apple
{
public void printColor()
{
System.out.print("Green");
}
}
public class Jonagold extends Apple
{
// no methods defined
}
The following statement appears in a method in another class.
someApple.printColor();
Under which of the following conditions will the statement print "Red" ?
I. When someApple is an object of type Apple
II. When someApple is an object of type GrannySmith
III. When someApple is an object of type Jonagold
a. I only
b. II only
c. I and III only

def area (width, height)
area = width * height
return area
boxlarea = area (5,2)
box2area = area (6)
What needs to change in order for the height in the area function to be 12 if a height is not specified when calling the function?
0 0 0 0
Add a height variable setting height =12 inside the function
Change the box2area line to box 2area = area (6,12)
Add a height variable setting height =12 before the function is declared
Change the def to def area (width, height = 12)
Answer:
D. Change the def to def area (width, height = 12)
Explanation:
Required
Update the function to set height to 12 when height is not passed
To do this, we simply update the def function to:
def area (width, height = 12)
So:
In boxlarea = area (5,2), the area will be calculated as:
[tex]area = 5 * 2 = 10[/tex]
In box2area = area (6), where height is not passed, the area will be calculated as:
[tex]area = 6 * 12 = 72[/tex]
why stress testing is needed?
Answer:
To be able to test a product if it can withstand what it is supposed to before being released to the public for saftey reasons.
Answer:
Stress testing involves testing beyond normal operational capacity, often to a breaking point, to observe the results. Reasons can include:
Helps to determine breaking points or safe usage limits Helps to confirm mathematical model is accurate enough in predicting breaking points or safe usage limits Helps to confirm intended specifications are being met Helps to determine modes of failure (how exactly a system fails) Helps to test stable operation of a part or system outside standard usage Helps to determine the stability of the software.Stress testing, in general, should put computer hardware under exaggerated levels of stress to ensure stability when used in a normal environment.

Answer:
The addition to the program is as follows: digit = 0
while digit <= 9:
print('%s%d.com' % (letter1, digit))
digit+=1
Explanation:
This initializes digit to 0
digit = 0
This loop is repeated from 0 to 9 (inclusive)
while digit <= 9:
This prints the domain (letter and digit)
print('%s%d.com' % (letter1, digit))
This increases the digit by 1 for another domain
digit+=1

The elements in a long array of integers are roughly sorted in decreasing order. No more than 5 percent of the elements are out of order. Which of the following is the best method to use to sort the array in descending order?
I. Insertion sort.
Il. Merge Sort.
III. Heap Sort.
a. Ill only.
b. I only.
c. II and III only.
d. I and II only.
e. Il only I and.
f. Ill only.
Question Completion with Options:
a. Ill only.
b. I only.
c. II and III only.
d. I and II only.
e. Il only
f. I and Ill only.
Answer:
The best method to use to sort the array in descending order is:
e. Il only
Explanation:
The Merge Sort is similar to the Insertion Sort but, it is better with its sorting versatility. It repeatedly breaks down a list into several sub-lists until each sub-list consists of a single element and then, merging the sub-lists in a manner that results in a sorted list. The Merge Sort has been described as a "divide and conquer" technique because of how it splits a list into equal halves before combining them into a sorted whole.

1. What is your biggest concern about cybercrime and why?
(please answer in at least 3 complete sentences)
Answer:
While it may seem like we are already overwhelmed by the amount of cyberattacks occurring daily, this will not slow down in 2018. In fact, with a recent increase in cybercriminal tools and a lower threshold of knowledge required to carry out attacks, the pool of cybercriminals will only increase. This growth is a likely response to news media and pop culture publicizing the profitability and success that cybercrime has become. Ransomware alone was a $1 billion industry last year. Joining the world of cybercrime is no longer taboo, as the stigma of these activities diminishes in parts of the world. To many, it’s simply a “good” business decision. At the same time, those already established as “top-players” in cybercrime will increase their aggressive defense of their criminal territories, areas of operations and revenue streams. We may actually begin to see multinational cybercrime businesses undertake merger and acquisition strategies and real-world violence to further secure and grow their revenue pipeline.

4. Interaction between seller and buyer is called___.
A. Demanding
B. Marketing
C. Transactions
D. Oppurtunity
Answer:
C. Transactions.
Explanation:
A transaction can be defined as a business process which typically involves the interchange of goods, financial assets, services and money between a seller and a buyer.
This ultimately implies that, any interaction between a seller and a buyer is called transactions.
For example, when a buyer (consumer) pays $5000 to purchase a brand new automobile from XYZ automobile and retail stores, this is referred to as a transaction.
Hence, a transaction is considered to have happened when it's measurable in terms of an amount of money (price) set by the seller.
Price can be defined as the amount of money that is required to be paid by a buyer (customer) to a seller (producer) in order to acquire goods and services. Thus, it refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. Also, the price of goods and services are primarily being set by the seller or service provider.

You are designing an application at work that transmits data records to another building in the same city. The data records are 500 bytes in length, and your application will send one record every 0.5 seconds
Is it more efficient to use a synchronous connection or an asynchronous connection? What speed transmission line is necessary to support either type of connection? Show all your work.
Solution :
It is given that an application is used to transmit a data record form one building to another building in the same city, The length of the data records is 500 bytes. and the speed is 0.5 second for each record.
a). So for this application, it is recommended to use a synchronous connection between the two building for data transfer as the rate data transfer is high and it will require a master configuration between the two.
b). In a synchronous connection, 500 bytes of data can be sent in a time of 0.5 sec for each data transfer. So for this the line of transmission can be either wired or wireless.
Given the following: int funcOne(int n) { n *= 2; return n; } int funcTwo(int &n) { n *= 10; return n; } What will the following code output? int n = 30; n = funcOne(funcTwo(n)); cout << "num1 = " << n << endl; Group of answer choices Error num1 = 60 num 1 = 30 num1 = 600 num1 = 300
Answer:
num1 = 600
Explanation:
Given
The attached code snippet
Required
The output of n = funcOne(funcTwo(n)); when n = 30
The inner function is first executed, i.e.
funcTwo(n)
When n = 30, we have:
funcTwo(30)
This returns the product of n and 10 i.e. 30 * 10 = 300
So:
funcTwo(30) = 300
n = funcOne(funcTwo(n)); becomes: n = funcOne(300);
This passes 300 to funcOne; So, we have:
n = funcOne(300);
This returns the product of n and 2 i.e. 300 * 2 = 600
Hence, the output is 600

5.19 LAB: Output values in a list below a user defined amount
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value.
Ex: If the input is:
5
50
60
140
200
75
100
the output is:
50,60,75,
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.
For coding simplicity, follow every output value by a comma, including the last one.
Such functionality is common on sites like Amazon, where a user can filter results.
Answer:
The program in Python is as follows:
n = int(input())
myList = []
for i in range(n):
num = int(input())
myList.append(num)
threshold = int(input())
for i in myList:
if i<= threshold:
print(i,end=", ")
Explanation:
This gets the number of inputs
n = int(input())
This creates an empty list
myList = []
This iterates through the number of inputs
for i in range(n):
For each iteration, this gets the input
num = int(input())
And appends the input to the list
myList.append(num)
This gets the threshold after the loop ends
threshold = int(input())
This iterates through the list
for i in myList:
Compare every element of the list to the threshold
if i<= threshold:
Print smaller or equal elements
print(i,end=", ")
The Python program below gets a list of integers, then filters that list based on a threshold value:
########################################################
# initialize the integer and output lists
integer_list = [ ]
output_list = [ ]
# first enter the number of integers that will follow
# and append it to integer list
qty = int(input("Enter the number of integers to follow: "))
integer_list.append(qty)
# next enter the number of integers and append them to integer list
for i in range(0, qty):
num = int(input("Enter an integer: "))
integer_list.append(num)
# finally enter the threshold value to be used to filter the integers
threshold = int(input("Enter the threshold value: "))
integer_list.append(threshold)
# filter the integers
for num in integer_list:
if num <= integer_list[-1]:
output_list.append(num)
# display the result
print("The values from { } that are less than or equal to { } are
{ }".format(integer_list[1:-1], integer_list[-1], output_list))
########################################################
The program first asks the user to enter the following:
The number of integers to be checkedThe integers themselvesThe threshold value to be used for filteringThe program next iterates over the integer list and filters the integers from index 1 to index -1(exclusive, since this is the threshold value) based on the element at index -1(the last element, the threshold value).
Each element that satisfies the filtering criterion (e <= threshold) is added to the output list and printed out later.

Overview In this assignment, you will gain more practice with designing a program. Specifically, you will create pseudocode for a higher/lower game. This will give you practice designing a more complex program and allow you to see more of the benefits that designing before coding can offer. The higher/lower game will combine different programming constructs that you have been learning about, such as input and output, decision branching, and a loop. IT 140 Higher/Lower Game Sample Output Overview Maria has asked you to create a program that prompts the user to enter the lower bound and the upper hound. You have decided to write pseudocode to design the program before actually developing the code. When run, the program should ask the user to guess a number. If the number guessed is lower than the random number, the program should print out a message like "Nope, too low." if the number guessed is higher than the random number, print out a message like "Nope, too high." If the number guessed is the same as the random number, print out a message like "You got it!" Higher/Lower Game Description Your friend Maria has come to you and said that she has been playing the higher/lower game with her three-year-old daughter Bella. Maria tells Bella that she is thinking of a number between 1 and 10, and then Bella tries to guess the number. When Bella guesses a number, Maria tells her whether the number she is thinking of is higher or lower or if Bella guessed it. The game continues until Bella guesses the right number. As much as Maria likes playing the game with Bella, Bella is very excited to play the game all the time, Maria thought it would be great if you could create a program that allows Bella to play the game as much as she wants. Note: The output messages you include in your pseudocode may differ slightly from these samples. Sample Output Below is one sample output of the program, with the user input demonstrated by bold font. Prompt For this assignment, you will be designing pseudocode for a higher/lower game program. The higher/lower game program uses similar constructs to the game you will design and develop in Projects One and TWO. Welcome to the higher/lower game, Bella! Enter the lower bound: 10 Enter the upper bound: 30 Great, now guess a number between 10 and 30: 20 Nope, too low Guess another number: 25 Nope, too high Guess another number: 23 You got it! Below is another sample output of your program, with the user input demonstrated by bold font 1. Review the Higher/Lower Game Sample Output for more detailed examples of this game. As you read, consider the following questions: What are the different steps needed in this program? How can you break them down in a way that a computer can understand? What information would you need from the user at each point (inputs)? What information would you output to the user at each point? When might it be a good idea to use 'F' and "IF ELSE' statements? When might it be a good idea to use loop? 2. Create pseudocode that logically outlines each step of the game program so that it meets the following functionality: Prompts the user to input the lower bound and upper bound. Include input validation to ensure that the lower bound is less than the upper bound. - Generates a random number between the lower and upper bounds Prompts the user to input a guess between the lower and upper bounds. Include input validation to ensure that the user only enters values between the lower and upper bound. Prints an output statement based on the puessed number. Be sure to account for each of the following situations through the use of decision branching . What should the computer output if the user guesses a number that is too low? . What should the computer output if the user guesses a number that is too high? - What should the computer output if the user guesses the right number? Loops so that the game continues prompting the user for a new number until the user guesses the correct number. Welcome to the higher/lower game, Bella! Enter the lower bound: 10 Enter the upper bound: 5 The lower bound must be less than the upper bound. Enter the lower bound: 10 Enter the upper bound: 20 Great, now guess a number between 10 and 20: 25 Nope, too high Guess another number: 15 Nope, too low. Guess another number: 17 You got it!
