Answer:
The answer is "Option b".
Explanation:
Function chaining is shown by this code, as the functions are called one after the other with one statement. Whenever you want to call a series of methods through an object, that technique is beneficial. Just because of that, you may give the same effect with less code and have a single given value only at top of the leash of operations.

Suppose you have a stack ADT (i.e., an Abstract Data Type that includes operations to maintain a stack. Design a flowchart or suitable logical diagram to show you could implement a queue’s enqueue and dequeue operations using two stacks, stack 1 and stack 2.
Answer:
One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.
Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).
Dequeueing would be:
- For all items in stack1: pop them from stack1 and push them in stack 2.
- Pop one item from stack2, which will be your dequeue result
- For all items in stack2: pop them from stack2 and push them in stack 1.
Hope it makes sense. I'm sure you can draw a diagram.

What is the easiest way to deploy a C++ program to a user’s computer? a. Copy the source code to the user’s computer and then compile it b. Create a batch file that copies the program to the user’s computer and then run it c. Copy the executable file to the user’s computer d. Create an installer program and then run it on the user’s computer
Answer:
c. Copy the executable file to the user’s computer
Explanation:
When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.
To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.
The program will work fine without errors.
However, do not mistake the executable file for the source file. The source file ends in .cpp.

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.
In this scenario, a security administrator is reviewing the following information from a file that was found on a compromised host: "cat suspiciousfile.txt."
Some of the ways to prevent vulnerability 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.
Write a program that creates an an array large enough to hold 200 test scores between 55 and 99. Use a Random Number to populate the array.Then do the following:1) Sort scores in ascending order.2) List your scores in rows of ten(10) values.3) Calculate the Mean for the distribution.4) Calculate the Variance for the distribution.5) Calculate the Median for the distribution.
Answer:
Explanation:
The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.
from random import randint
import numpy as np
test_scores = []
for x in range(200):
test_scores.append(randint(55, 99))
sorted_test_scores = sorted(test_scores)
count = 0
print("Scores in Rows of 10: ", end="\n")
for score in sorted_test_scores:
if count < 10:
print(str(score), end= " ")
count += 1
else:
print('\n' + str(score), end= " ")
count = 1
mean = np.mean(sorted_test_scores)
variance = np.var(sorted_test_scores, dtype = np.float64)
median = np.median(sorted_test_scores)
print("\n")
print("Mean: " + str(mean), end="\n")
print("Variance: " + str(variance), end="\n")

sum_b = 0
sum_c = 0
for i = 0 to 20
sum_a = sum_a + x^i
sum_b = sum_b + (-x)^i
sum_c = sum_c + x^i/(i+1)
print sum_a, sum_b, sum_c
Explanation:
Required
An algorithm to solve (a), (b) and (c)
For Series (a):
This series is a geometric progression and the common ratio is x
i.e.
[tex]r = x/1 = x^2/x = ...... = x^{n+1}/x^n =x[/tex]
So, the sum of the series is:
Sum = Previous Sums + x^i --- where i is between 0 and 20 (inclusive)
For Series (b):
This series is a geometric progression and the common ratio is -x
i.e.
[tex]r = -x/1 = -x^2/x = ...... = -(x^{n+1}/x^n) = -x[/tex]
So, the sum of the series is:
Sum = Previous Sums + (-x^i) --- where i is between 0 and 20 (inclusive)
For Series (c):
This series is a neither arithmetic nor geometric progression.
It obeys the following rule:
[tex]\frac{x^i}{1+i}[/tex] --- where i is between 0 and 20 (inclusive)
So, the sum of the series is:
Sum = Previous Sums + [tex]\frac{x^i}{1+i}[/tex]
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))
Answer:
The program in Python is as follows:
current_price = int(input("Current Price: "))
last_price = int(input("Last Month Price: "))
change = current_price - last_price
mortgage = (current_price * 0.051) / 12
print('Change: {:.2f} '.format(change))
print('Mortgage: {:.2f}'.format(mortgage))
Explanation:
This gets input for current price
current_price = int(input("Current Price: "))
This gets input for last month price
last_price = int(input("Last Month Price: "))
This calculates the price change
change = current_price - last_price
This calculates the mortgage
mortgage = (current_price * 0.051) / 12
This prints the calculated change
print('Change: {:.2f} '.format(change))
This prints the calculated monthly mortgage
print('Mortgage: {:.2f}'.format(mortgage))
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='0.\n')
Part 1 - Write the ingredients list to a file (10 points) Modify the program you developed for Lab 5 to make it output the data in the same format to a text file cake_ingredients_list.txt Note: Writing to a file is easier to code, so let's do that first. Hints: After the file has been opened, call the .write() function to write one line at a time to the file, in almost the exact fashion as calling print
Answer:
Explanation:
I do not have access to the ingredients list so instead I created the list and added the ingredients needed to make a cake. Then I used a for loop to loop throught the ingredients in the list and the .write() method to write the data to a text file with the same name as in the question. The code was tested and the output to the file can be seen in the attached image below.
ingredients = ['sugar', 'butter', 'eggs', 'vanilla', 'flour', 'baking powder', 'milk']
file = open('cake_ingredients_list.txt', 'w')
for ingredient in ingredients:

Write a program that inputs a line of text tokenizing the line with function strtok and outputs the tokens in reverse order i.e. last token in the sentence is printed first and first token is printed last. The user must be able to specify at most 80 characters in the sentence.
Answer and Explanation:
var gettext= prompt("please enter text");
function strtok(gettext){
var splitString = gettext.split("");
if(splitString.length<=80){
var reverseArray = splitString.reverse();
var joinArray = reverseArray.join("");
return joinArray;}
else{
Alert("too many characters");
}
}
/* we first ask for user input using the prompt function. We save this in a variable gettext which we pass to the strtok function. This function first splits the text and makes it an array so we are able to count how many characters the user enters and set an if..else condition to handle characters that may be more than 80. The reverse and join functions are then used respectively to reverse and return the string.*/

In the context of the components of a typical expert system, _____ is similar to a database, but in addition to storing facts and figures it keeps track of rules and explanations associated with facts.
Answer:
Knowledge base.
Explanation:
Artificial intelligence (AI) also known as machine learning can be defined as a branch of computer science which typically involves the process of using algorithms to build a smart computer-controlled robot or machine that is capable of performing tasks that are exclusively designed to be performed by humans or with human intelligence.
Artificial intelligence (AI) provides smarter results and performs related tasks excellently when compared with applications that are built using conventional programming.
Generally, there are two (2) main characteristics of artificial intelligence (AI) systems and these include;
I. Non-algorithmic processing.
II. Symbolic processing.
In artificial intelligence (AI), the field of expert systems is the most important applied area because it models human knowledge.
Hence, expert systems represents knowledge as a set of rules by mimicking the expertise of humans in a particular field to uniquely proffer solutions to a problem.
Although, all expert systems are generally lacking in human capabilities and can only use inference procedures to proffer solutions to specific problems that would normally require human expertise or competence.
Some of the areas where expert systems can be applied are; monitoring, diagnosis, scheduling, classification, design, process control, planning, etc.
Basically, expert systems comprises five (5) main components and these are;
1. Explanation module.
2. Inference Engine.
3. Knowledge acquisition and learning module.
4. User Interface.
5. Knowledge Base.
In the context of the components that makes up an expert system, knowledge base is similar to a database because it is used for storing facts and figures, while keeping track of rules and explanations associated with facts. Thus, giving rise to the knowledge base management system (KBMS).
In the context of the components of a typical expert system, Knowledge base is similar to a database, but in addition to storing facts and figures, it keeps track of rules and explanations associated with facts.
An expert system is a form of artificial intelligence where computer imitate the decision making style of humans.
There are basically two types of the expert system and they are the inference engine and the knowledge base.
The knowledge base consists of the facts and rules and ways of interpreting them to arise to new insights. The inference engine applies logical rules to the knowledge base.
