Based on the data definition classes identified below, assume you wish to create a Dictionary class that inherits from the Book class. In addition to title and cost, the Dictionary class must also store the number of words present in the dictionary. Write the code that will create a constructor in the dictionary class that passes in and sets the dictionary's title, cost, and number of words.

public class Book {
private String title;
private double cost;

public Book(String title) {
this(title, 0.00);
}

public Book(String title, double cost) {
this.title = title;
this.cost = cost;
}

public String getTitle() { return this.title; }
public double getCost() { return this.cost; }
}

public class Dictionary extends Book {
private double numWords;

// Create Contructor

Answer:

Explanation:

The following code is written in Java. It assumes that the numbers.txt file is in the same folder as the Java file and the numbers are separated one on each line. It reads the file, adds all the numbers to an array, then adds the numbers into a single variable and finally divides by the total amount of numbers in order to get the average.

public static void main(String[] args) {

       ArrayList<Integer> numbers = new ArrayList();

       try {

           File myObj = new File("numbers.txt");

           Scanner myReader = new Scanner(myObj);

           while (myReader.hasNextLine()) {

               String data = myReader.nextLine();

               numbers.add(Integer.parseInt(data));

           }

           myReader.close();

       } catch (FileNotFoundException e) {

           System.out.println("An error occurred.");

           e.printStackTrace();

       }

       int average = 0;

       for (int x:numbers) {

           average += x;

       }

       average = average / numbers.size();

       System.out.println(average);

   }

Answer:

There should be a double space between each citation

The citation entries should be in alphabetical order.

The second and third lines of the last entry should be indented

Explanation:

The bibliography page contains some formatting errors which should be corrected before it is standard and acceptable.

First of all, in MLA (and most other styles), it is important to double space each citation to make them easily readable and eliminate errors.

Next, the citation entries needs to be in alphabetical order and not random which makes it easy to find a source.

Also, there needs to be indentation in the second and third lines of the last entry.

Answer and Explanation:

Subprograms are nested three deep hence we would have three subprograms/functions under one program(function)

We call the program/function MotherFunction( using camel case variable naming rules)

function MotherFunction() {

var mother= 8;

console.log(mother);

function subDaughter1() {

var subDaughter1X = mother + 12;

console.log(subDaughter1X);

function subDaughter2() {

var subDaughter2X= mother + 5;

console.log(subDaughter2X);

function subDaughter3() {

var subDaughter3X= mother + 3;

console.log(subDaughter3X);

alert("sum="+subDaughter1X+subDaughter2X+subDaughter3X);

}

}

}

}

MotherFunction();

We created the first function and nested subfunctions under it, adding up the variable from the parent function(mother function) to its subfunctions and then alerting the total value of all the subfunction variables summed in the last/third subfunction. We then called the function after defining it.

Convert 1.5GB to KBs = 1500000kb

1500000kb/950kb ≈ 1579

Explanation:

A flash disk is a storage device. It has enough memory to store large files. In the given question, the flash disk has a memory of 1.5GB and can store 1578.94 music files of 950KBs each.

A flash disk is a data storage device that uses flash memory specifically : a small rectangular device which is designed to be plugged directly into a USB port on a computer. It is often used for transferring files from one computer to another computer system.

Flash disks have no mechanical platters or access arms. It is termed "disk" because of the data which are accessed as if they were on a hard drive. The disk storage structure is emulated.

In the given question, the flash disk contains 1.5GB memory and has to store music files of 950KBs each. For determining the number of music files which can be stored in the flash disks, we have to first convert the unit of flash disk from GB to KB:

1GB = 1,000,000 KB

1.5 GB = 1,500,000 KB

size of music file = 950 KB

Number of music files that can be stored = storage in the flash disk ÷ size of the music file

Number of music files = 1500000KB ÷ 950KB

Number of music files = 1578.94

Answer:

mylist = []

vowel = ['a', 'e', 'i', 'o', 'u']

vowelcount = 0

consonantcount = 0

digitcount = 0

string = " "

number = [ str(i) for i in range(0, 10)]

while endinput == "no":

   inputs = input("Enter string value: ")

   mylist.append(inputs)

   endinput = input("Do you want to end input? ( enter no to continue:  ")

for item in mylist:

   txt = item

   print(txt)

   for i in txt:

       if i == string:

           continue

       elif i in vowel:

           vowelcount +=1

       elif i in number:

           digitcount += 1

       else:

           consonantcount += 1  

print("Vowels: ", vowelcount)

print("Digits: ", digitcount)

print("Consonant: ", consonantcount)

Explanation:

The python program receives one or more strings from the standard input and appends it to a list. The algorithm iterates through the list of string values and counts the number of vowels, consonants, and digits.

correct = (["1.B", "6.A", "11.B", "16.C","2.D", "7.B", "12.C", "17.C", "3.A", "8.A", "13.D", "18.B","4.A" ,"9.C", "14.A", "19.D","5.C", "10.D", "15.D", "20.A"])

f = open("MyFile.txt", "r")

user_answers = ([])

count = 0

txt = ""

for x in f.read():

   if x == " " or x == "\n":

       x = ""

       count += 1

   if count == 2 :

       user_answers.append(txt)

       txt = ""

       count = 0

   txt += x

i = 0

cor = 0

wrong = ([])

while i < len(correct):

   if correct[i] == user_answers[i]:

       cor += 1

   else:

       wrong.append(user_answers[i])

   i += 1

questions = ([])

for i in wrong:

   txt = ""

   for w in i:

       if w == ".":

           questions.append(int(txt))

       txt+=w

print("There were {} correct answers".format(cor))

print("There were {} incorrect answers".format(len(questions)))

print("The incorrectly answered questions are {}".format(questions))

f.close()

The file I used for testing looks like:

1. C 6. A 11. B 16. C

2. D 7. B 12. C 17. C

3. A 8. D 13. D 18. D

4. A 9. C 14. A 19. A

5. C 10. D 15. D 20. C

The code only works if there is a new line after 20. C (press enter after that question if a new line isn't already included)

I hope this helps!

Explanation:

DDE (direct data entry) devices are the devices that read data from a source and transfer it directly into the computer. Unlike, other input devices which require physical interaction which requires you to move physically or to do something for an output or feeding data into a computer.  

The DDE devices require no hard work while taking input into the computer as compared to other input devices. These DDE devices made our life very easy. Because these devices take input accurately and there are no chances of human error.

The example of DDE devices are magnetic stripe reader, chip reader, Pin pads, optical mark reader, and barcode reader, etc.

These devices have brought great advantages to human life. Because by using these data entry devices, information can be put into very quickly, more accurate than typing and information of the whole page transferred .very quickly and accurately into the system. These devices are also more secure and can hold lots of data, and the data is protected with the PIN (personal identification number). These are also used in ATM machines, handheld, and entry doors.

Answer:

Explanation:

The following is written in Java. It is a method/function that takes the oldScore as an int input. It turns it into a String, separates all the digits, puts them into an array. Then adds the first digit to the end and removes it from the beginning, thus shifting the entire score one to the left. Then it turns the String variable back into an Integer called finalScore and prints it out.

public static void newScore(int oldScore) {

       ArrayList<Integer> newScore = new ArrayList<>();

       String stringOldScore = String.valueOf(oldScore);

       for (int x = 0; x < stringOldScore.length(); x++) {

           newScore.add(Integer.parseInt(String.valueOf(stringOldScore.charAt(x))));

       }

       newScore.add(newScore.get(0));

       newScore.remove(0);

       String newScoreString = "";

       for (int x:newScore) {

           newScoreString += String.valueOf(x);

       }

       int finalScore = Integer.parseInt(newScoreString);

       System.out.println(finalScore);
