You enqueue 5 elements, dequeue 5 elements, and then enqueue 1 more element. Which index of the internal array elements holds the value of that last element you enqueued
Answer:
The answer is "5".
Explanation:
In the queue based-array, it follows the FIFO method, and in the question, it is declared that a queue has a capacity of 10 elements, and insert the 5 elements in the queue and after inserting it enqueue 5 elements and at the last, it inserts an element 1 more element on the queue and indexing of array always start from 0, that's why its last element index value is 5.
Research an organization that is using supercomputing, grid computing or both. Describe these uses and the advantages they offer. Are they a source of competitive advantage? Why or why not? Please be sure to include your reference(s).
Answer:
Procter and Gamble is an organization that uses supercomputing.
Explanation:
Supercomputing refers to the use of high-performance computers in the development and production of items. Procter and Gamble is a company known for the production of many household items and personal care products. Uses and advantages of supercomputing to this company include;
1. Testing virtual prototypes of substances used in production: This is a faster way of developing products that are sustainable because many prototypes can be examined with the help of computers and the best chosen for production.
2. Developing unique designs of products: Supercomputers allow for the development of high-quality designs which include the internal and external designs of products.
3. Simulation of many molecules: Molecules such as those involved in the production of surfactants can be analyzed to understand how they work with the aid of supercomputers.
4. Computational fluid dynamics: This helps the scientists to understand how fluid works using numerical analysis and the structure of compounds.
The designs and products obtained through supercomputing are a source of competitive advantage because the company can make high-quality and unique products that appeal to customers and meet the latest trends. This would increase their marketability and give them an advantage over companies that do not have access to these computers.

Microcomputers/personal computerMini computersMainframe computerssuper computersWorks in the public domain have copyright that are expired or abandoned true or false
Answer:
False
Explanation:
Only one of the two are true. Works in the public domain have a copyright that has expired only. E.g. Works of classical music artist, are almost always expired, in accorance with American Copyright law. Abandoning a copyright doesn't do anything because so long the copyright has remained unexpired, the copyright remains. Thats why it can take decades for a new movie in a series to release, like "IT" by Stephen King. The copyright hasn't expired but rather was 'abandoned'. Before "IT" 2017 was relasesed, the copyright was abandoned.

Explanation:
This assignment requires you to write a program to analyze a web page HTML file. Your program will read one character at a time from the file specifying the web page, count various attributes in the code for the page, and print a report to the console window giving information about the coding of the page.
Note that a search engine like Google uses at least one technique along similar lines. To calculate how popular (frequently visited or cited) a web page is, one technique is to look at as many other worldwide web pages as possible which are relevant, and count how many links the world's web pages contain back to the target page.
Learning Objectives
To utilize looping structures for the first time in a C++ program
To develop more sophisticated control structures using a combination of selection and looping
To read data from an input file
To gain more experience using manipulators to format output in C++
To consider examples of very simple hypertext markup language (HTML)
Use UNIX commands to obtain the text data files and be able to read from them
Problem Statement
Your program will analyze a few things about the way in which a web page is encoded. The program will ask the user for the name of a file containing a web page description. This input file must be stored in the correct folder with your program files, as discussed in class, and it must be encoded using hypertext markup language, or HTML. The analysis requires that you find the values of the following items for the page:
number of lines (every line ends with the EOLN marker; there will be an EOLN in front of the EOF)
number of tags (includes links and comments)
number of links
number of comments in the file
number of characters in the file (note that blanks and EOLNs do count)
number of characters inside tags
percentage of characters which occur inside tags, out of the total
Here is an example of a very simple HTML file:
Course Web Page
This course is about programming in C++.
Click here
You may assume that the HTML files you must analyze use a very limited subset of basic HTML, which includes only the following "special" items:
tag always starts with '<' and ends with >
link always starts with "
comment always starts with ""
You may assume that a less-than symbol (<) ALWAYS indicates the start of a tag. A tag in HTML denotes an item that is not displayed on the web page, and often gives instructions to the web browser. For example, indicates that the next item is the overall title of the document, and indicates the end of that section. In tags, both upper and lowercase letters can be used.
Note on links and comments: to identify a link, you may just look for an 'a' or 'A' which occurs just after a '<'. To identify a comment, you may just look for a '!' which follows just after a '' (that is, you do not have to check for the two hyphens).
You may assume that these are the only HTML language elements you need to recognize, and that the HTML files you process contain absolutely no HTML syntax errors.
Note: it is both good style because readability is increased, and convenient, to declare named constants for characters that are meaningful, for example
const char TAG OPEN = '
Sample Input Files
Program input is to be read from a text file. Your program must ask the user for interactive input of the file name. You can declare a variable to store the file name and read the user's response
Miscellaneous Tips and Information
You should not read the file more than once to perform the analysis. Reading the file more than once is very inefficient.
The simplest, most reliable and consistent way to check for an end of file condition on a loop is by checking for the fail state, as shown in lectures. The eof function is not as reliable or consistent and is simply deemed "flaky" by many programmers as it can behave inconsistently for different input files and on different platforms.
You may use only while loops on this project if you wish; you are not required to choose amongst while, do while and/or for loops until project 4 and all projects thereafter. Do not create any functions other than main() for this program. Do not use data structures such as arrays. You may only have ONE return statement and NO exit statements in your code. You may only use break statements inside a switch statement in the manner demonstrated in class; do not use break or continue statements inside loops.

individuals should
as possible.
A. position their seats as far forward
B. position their seats as far back
c. recline their seats as far back
D. none of the above
Answer:
B. position their seats as far back
Explanation:
An airbag can be defined as a vehicle safety device (bag) that is designed to be inflated and eventually deflated in an extremely rapid or quick manner during an accident or collision.
Basically, an airbag refers to an occupant-restraint safety device installed on vehicles to protect both the driver and front-seat passenger in the event of an accident or collision. An airbag typically comprises of an impact sensor, flexible fabric bag, airbag cushion and an inflation module.
In order to prevent any unnecessary injuries to small adults and the elderly from a deploying airbag, these individuals should position their seats as far back as possible. This ultimately implies that, both the driver and the front-seat passenger are advised not to position too close to the dashboard; the seats should be as far back as possible.
Explain why it is not necessary for a program to be completely free of defects before it is delivered to its customers?
Answer:
Testing is done to show that a program is capable of performing all of its functions and also it is done to detect defects.
It is not always possible to deliver a 100 percent defect free program
A program should not be completely free of all defects before they are delivered if:
1. The remaining defects are not really something that can be taken as serious that may cause the system to be corrupt
2. The remaining defects are recoverable and there is an available recovery function that would bring about minimum disruption when in use.
3. The benefits to the customer are more than the issues that may come up as a result of the remaining defects in the system.

Write an if statement that assigns 20 to the variable y, and assigns 40 to the variable z if the variable x is greater than 100. python
Answer:
if x > 100:
y = 20
z = 40
Explanation:
This line checks if variable x is greater than 100
if x > 100:
This line assigns 20 to y
y = 20
This line assigns 40 to z
z = 40
The if statement that assigns 20 to the variable y, and assigns 40 to the variable z if the variable x is greater than 100 is as follows:
x = int(input("input an integer number: "))
if x > 100:
y = 20
z = 40
print(y)
print(z)
The first code we ask the user to input an integer number and stored it in the
variable x.
If the user input is greater than x, then y is assigned to 20 and z is assigned to 40.
We print the assigned value of y and z if the user entered an input greater
than 100.

Answer:
Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted by a communications satellite orbiting the Earth and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.Explanation:

Introduction
For this assignment you will write an encoder and a decoder for a modified "book cipher." A book cipher uses a document or book as the cipher key, and the cipher itself uses numbers that reference the words within the text. For example, one of the Beale ciphers used an edition of The Declaration of Independence as the cipher key. The cipher you will write will use a pair of numbers corresponding to each letter in the text. The first number denotes the position of a word in the key text (starting at 0), and the second number denotes the position of the letter in the word (also starting at 0). For instance, given the following key text (the numbers correspond to the index of the first word in the line):
[0] 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe;
[13] All mimsy were the borogoves, And the mome raths outgrabe.
[23] "Beware the Jabberwock, my son! The jaws that bite, the claws that catch!
[36] Beware the Jubjub bird, and shun The frumious Bandersnatch!"
[45] He took his vorpal sword in hand: Long time the manxome foe he sought—
The word "computer" can be encoded with the following pairs of numbers:

else: #if word does not appear in any song
return f'No songs were found to contain the words:{word}' #returns this message if no songs were found with given word
print(NumberOfSongs('like')) #calls method with the word like given as parameter to it
Explanation:
You can add the csv file this way:
import pandas as pd
lyrics = pd.read_csv("lyrics.csv", encoding="cp1252")
Now you can use the NumberOfSongs method which iterates through the Lyrics of lyrics.csv and find if any of the songs in the file contains the specified word.
The screenshot of program along with its output is attached. Since the file was not provided i have created a csv file. You can add your own file instead of lyrics.csv
