Answer:

Here is the Python code.

import csv  

inputfile = input("Enter name of the file: ")

count = {}

with open(inputfile, 'r') as csvfile:

 csvfile = csv.reader(csvfile)

 for line in csvfile:

   for words in line:

     if words not in count.keys():

       count[words] = 1

     else:

         count[words] + 1

   print(count)

Explanation:

I will explain the code line by line.

import csv   here the css is imported in order to read the file using csv.reader() method

inputfile = input("Enter name of the file: ")  This statement takes the name of the input file from the user

count = {}  this is basically a dictionary which will store the words in the file and the number of times each word appears in the file.

with open(inputfile, 'r') as csvfile:  This statement opens the inputfile using open() method in read mode. This basically opens the input file as csv type

 csvfile = csv.reader(csvfile)  This statement uses csv.reader() method to read the csv file contents.

for line in csvfile:  This outer for loop iterates through each line of the file

for words in line:  This inner loop iterates through each word in the line

if words not in count.keys():  This if condition checks if the word is not in the dictionary already. The dictionary holds key value pair and keys() method returns a list of all the keys of dictionary

count[words] = 1  if the word is not present already then assign 1 to the count dictionary

co unt[words] + 1 if the word is already present in dictionary increment count of the words by 1. Suppose the input file contains the following words:

hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy

Then because of co unt[words] + 1 statement if the word appears more than once in the file, then it will not be counted. So the output will be:

{' cat': 1, ' man': 1, ' dog': 1, ' woman': 1, ' Hello': 1, ' hey': 1, ' boy': 1, 'hello': 1, ' Cat': 1}

But if you want the program to count those words also in the file that appear more than once, then change this co unt[words] + 1 statement to:  

count[words] = count[words] + 1

So if the word is already present in the file its frequency is increased by 1 by incrementing 1 to the count[words]. This will produce the following output:

{' Cat': 1, ' cat': 2, ' boy': 2, ' woman': 1, ' dog': 2, ' hey': 2, ' man': 2, ' Hello': 1, 'hello': 1}  

You can see that cat, boy, dog and hey appear twice in the file.                    

print(count) This statement prints the dictionary contents with words and their frequencies.

The program with its output is attached.

The program is an illustration of file manipulations.

File manipulations involve reading from and writing into files.

The program in Python, where comments are used to explain each line is as follows:

#This imports csv module

import csv  

#This initializes a dictionary

kounter = {}

#This gets input for the file name

fname = input("Filename: ")

#This opens and iterates through the file

with open(fname, 'r') as cfile:

   #This reads the csv file

   cfile = csv.reader(cfile)

   #This iterates through each line

   for line in cfile:

       #This iterates through each word on each line

       for words in line:

           #This counts the occurrence of each word

           if words not in kounter.keys():

               kounter[words] = 1

           else:

               kounter[words] + 1

#This prints the occurrence of each word

print(kounter)

International_Spanish = f'{day} {spanish_month}'

print(f'US English Form: {US_English}')

print(f'International Spanish Form: {International_Spanish}')

Input:

3/5

Output:

US English Form: March 5

International Spanish Form: 5 Marzo

Explanation:

You start by taking input from the user then splitting that at the '/' so that we have the date and the month in separate variables. Then we have an if statement checking to see what month is given and when the month is detected it sets a Spanish variable and an English variable then prints it to the screen.

Answer:

a. Compile code

Explanation:

In programming process, the following are important in defining what a program is to do;

i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program.  The purpose of a program should be defined in the program.

ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.

iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.

iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.

Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.

def getN(num):

     fact = 1

     for i in range(1, 1 + num):

           fact = fact * i

     print("Factorial: ",fact)

num = int(input("Number: "))

if num < 0:

     print("Invalid")

else:

     getN(num)

Explanation:

The function getNum is defined here

def getN(num):

Initialize the result of the factorial to 1

     fact = 1

Get an iteration from 1 to the user input number

     for i in range(1, 1 + num):

Multiply each number that makes the iteration

           fact = fact * i

Print result

     print("Factorial: ",fact)

Ths line prompts user to input number

num = int(input("Number: "))

This line checks if user input is less than 0; If yes, the program prints "Invalid"

if num < 0:

Explanation:

Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995.

Java was designed by a software engineer called James Gosling and it is originally owned by Oracle. Also, worthy of mention is the fact that Java was originally known as Oak.

Generally, Java as a software application usually are developed having a ".jar", ".class" or ".java" filename extensions.

Because Java byte code is the same on all computers, compiled Java programs are highly portable. This simply means that, the Java byte code was designed such that it has very few implementation dependency, thus, once the code is written, it can run on all computer platforms that supports the Java programming language.

Hence, the Java byte code is a write once, run anywhere software program.

The Java byte code instructions are read and executed by a computer program known as a Java Virtual Machine (JVM).

Additionally, Java program is used for developing varieties of applications such as, mobile, desktop, games, web and application servers etc.

Answer:  

I am writing a Python program:

For taking input from user:

user_input = input() # takes input from user

short_names = user_input.split() #splits user_input into list of strings

short_names.pop(0) # removes the first element of the list i.e. Gertrude

short_names[-1] = "Joe" #sets the last element to Joe

print(short_names)    #prints modified list of Sam Ann Joe

If you do not want to take input from user:  

short_names=['Gertrude', 'Sam', 'Ann', 'Joseph']  #list of 4 elements

short_names=short_names[1:]  # removes the first element Gertrude

short_names.pop()  # removes last element i.e. Joseph from list

short_names.append('Joe')  #adds Joe to the end of the list

print(short_names) #prints modified list Sam Ann Joe

If you do not want to use pop() and append() methods:

short_names = ['Gertrude', 'Sam', 'Ann', 'Joseph']  #creates list of 4 values

short_names = short_names[1:]  # removes first value i.e. Gertrude from list

short_names[-1] = "Joe"  #set the last element to Joe

print(short_names) #prints modified list Sam Ann Joe

Explanation:

The first program takes the names from the user, splits them into list of strings, then pop(0) has given index value 0 which means 1st value in the list. So it removes and returns first value from the list. Next statement sets the last value of list to Joe.

The second program has a hard coded list ['Gertrude', 'Sam', 'Ann', 'Joseph']  

short_names = short_names[1:] removes the first value of the short_names list i.e. Gertrude. Next pop() removes and returns last value in the list i.e. Joseph from list. Last statement append('Joe') adds Joe to the end of the list.

The third program has a list of 4 elements. short_names = short_names[1:]   removes first value i.e. Gertrude from list and short_names[-1] = "Joe"  sets the last element to Joe.

The function was implemented using the JavaScript language, the shift, pop and push function was used to get the desired output

The function bellow is written in JavaScript

function shortName (short_names){

short_names.shift() // The first element "Gertrude" was removed

short_names.pop() //The last element "Joseph" was removes

short_names.push("joe") //"Joe" is added to the new list

return short_names //The new list is returned as output

Answer:

C. The main method proceeds to the next statement following the t3.join(); statement

Explanation:

join() method allows the thread to wait for another thread and completes its execution. If the thread object is executing, then t3.join() will make that t is terminated before the program executes the instruction. Thread provides the method which allows one thread to another complete its execution. If t is a thread object then t.join() will make that t is terminated before the next instruction. There are three overloaded functions.

join()

join(long mills)

join(long millis, int Nanos)

If multiple threads call the join() methods, then overloading allows the programmer to specify the period. Join is dependent on the OS and will wait .

b = float(input("User Input: "))

while not b==0:

    newlist.append(b)

    b = float(input("User Input: "))

newlist.sort()

print("Largest element is:", newlist[-1])

Explanation:

This line gives the user instruction on how to populate the list and how to stop

print("Enter elements into the list. Enter 0 to stop")

This line creates an empty list

newlist = []

This line enables the user to input numbers; float datatype was used to accommodate decimal numbers

b = float(input("User Input: "))

The italicized gets input from the user until s/he enters 0

while not b==0:

    newlist.append(b)

    b = int(input("User Input: "))

This line sorts the list in ascending order

newlist.sort()

The last element of the sorted list which is the largest element is printed using the next line

print("Largest element is:", newlist[-1])

The Encryption solution that best prevents a competitor from receiving confidential information is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).

Explanation:

Solution:

From my own perspective the encryption solution that i will use that prevents s a competitor from receiving confidential information and justify the recommendation is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).

This is because in this case we have to share data confidentially (information need to be hidden from Unauthorized  security access. also these provides the Transport Layer security that we needed in above example above.

The purpose of these protocol is to provide server and client authentication, Data confidentiality,and Data integrity (protected from unauthorized change). Application Layer client/server program such as HTTP that uses the service of TCP can encapsulate their data in SSL Packets.

SSL (Secure Socket Layer): is defined as the normal technology for protecting an internet connection secure and defend any sensitive data that is being sent between two systems, and not allowing criminals from reading and changing any information sent, including potential personal details.

TLS (Transport Layer security): It is a procedure that allows  data integrity  and privacy over Internet communications.

It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program is a "true statement" or the first option. It is very natural for a programmer/developer to come up with test that will run through every possible outcome in a program. Doing so will help the developer find things that might cause problems with the program in later time.

Hope this helps.

The answer to the question about the feasibility of a programmer to always come up with test cases that run through every possible path in a program is:

This refers to the set of actions which a programmer performs to find out if his software or program passes the system requirements in order to work properly.

With this in mind, we can see that while in some cases, it is possible for the programmer to come up with test cases, but it is not feasible in all cases as there can be hardware error which a virtual machine cannot solve.

141.95|212.95|312.95|10.95|

Reformatting the code snippet and giving it line numbers;

1.       var totals = [141.95, 212.95, 411, 10.95];

2.      totals[2] = 312.95;

3.      var totalsString = "";

4.      for (var i = 0; i < totals.length; i++) {

5.          totalsString += totals[i] + "|";

6.      }

Line 1 creates an array called totals with four elements.

     First element = totals[0] =141.95

     Second element = totals[1] = 212.95

     Third element = totals[2] = 411

     Fourth element = totals[3] = 10.95

Line 2 replaces the value of the third element totals[2] = 411 with 312.95.

     Therefore the array totals = [141.95, 212.95, 312.95, 10.95]

Line 3 creates an empty string called totalsString

Lines 4 - 6 create a for loop that cycles from i=0 to i<totals.length

       totals.length = 4 (which is the number of items in the array totals)

       This means that the loop cycles from i=0 to i<4

       During cycle 1 when i = 0, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[0] + "|"   //substitute the values

            totalsString = "" + 141.95 + "|"

            totalsString = 141.95|

       During cycle 2 when i = 1, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[1] + "|"   //substitute the values

            totalsString = "141.95|" + 212.95 + "|"

            totalsString = 141.95|212.95|

       During cycle 3 when i = 2, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[2] + "|"   //substitute the values

            totalsString = "141.95|212.95|" + 312.95 + "|"

            totalsString = 141.95|212.95|312.95|

       During cycle 4 when i = 3, the expression inside the for loop executes as follows;

            totalsString = totalsString + totals[3] + "|"   //substitute the values

            totalsString = "141.95|212.95|312.95|" + 10.95 + "|"

            totalsString = 141.95|212.95|312.95|10.95|

Answer:

Explanation:

Given that:

number of surfaces on a hard disk = 4

number of sectors = 2048 sectors

number of tracks per surface = 131, 072 (2^17)

a block holds 512 bytes.

Since, 'The disk is not "zoned.".....

then, Number of bytes / sector = 512

a) What is the total capacity of this disk?

The total capacity of the disk is:[tex]= 4 \ surfaces \times 131072 \dfrac{tracks}{surfaces} \times 2048 \dfrac{sector}{tracks} \times 512 \dfrac{bytes}{sector}[/tex]

[tex]= 5.49755814\times 10^{11} \ bytes[/tex]

= 549755814 KB ( kilobytes)

= 549755.814 MB (megabytes)

=549.755814  GB (gigabytes)

b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (i.e what is the capacity of one cylinder?)

The capacity of one cylinder can be estimated by determining the capacity of one surface and the capacity of one track.

The capacity of one surface = [tex]131072\dfrac{tracks}{surface} \times 2048 \dfrac{sector}{tracks} \times 512\dfrac{bytes}{sector}[/tex]

The capacity of one surface = [tex]1.37438953 \times 10^{11[/tex] byte = 137.44 GB

Capacity of one track = 2048 sectors/track × 512 bytes/sector

Capacity of one track = 1048576 Bytes/track

Capacity of one track =1048 KB/track

Capacity of one track ≅ 1 MB/track

Since the hard disk contains four surfaces

∴

capacity of one cylinder = 1 MB/track × 4 track/cylinder

capacity of one cylinder  = 4 MB
