Answer:

The modified program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

 int arrowHeadWidth, arrowBaseWidth, arrowBaseHeight;

 System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();

 System.out.print("Base Height: "); arrowBaseHeight = input.nextInt();

 while (arrowHeadWidth <= arrowBaseWidth) {

       System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();      }

 for(int i = 0; i<arrowBaseHeight; i++){

     for(int j = 0; j<arrowBaseWidth;j++){

         System.out.print("*");        }

         System.out.println();    }

 for(int i = arrowHeadWidth; i>0;i--){

     for(int j = 0; j<i;j++){

         System.out.print("*");        }

         System.out.println();    }

}

}

Explanation:

This declares the arrow dimensions

 int arrowHeadWidth, arrowBaseWidth, arrowBaseHeight;

This get input for the head width

 System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

This get input for the base width

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();

This get input for the base height

 System.out.print("Base Height: "); arrowBaseHeight = input.nextInt();

This loop is repeated until the head width is greater than the base width

 while (arrowHeadWidth <= arrowBaseWidth) {

       System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();      }

This iterates through the base height

 for(int i = 0; i<arrowBaseHeight; i++){

This iterates through the base width

     for(int j = 0; j<arrowBaseWidth;j++){

This fills the base

         System.out.print("*");        }

This prints a new line

         System.out.println();    }

These iterate through the arrow head

 for(int i = arrowHeadWidth; i>0;i--){

     for(int j = 0; j<i;j++){

This fills the arrow head

         System.out.print("*");        }

This prints a new line

         System.out.println();    }

Consider the following class definition.public class Tester

The following statement appears in a method in a class other than Tester. It is intended t o create a new Tester object t with its attributes set to 10 and 20.
Tester t = new Tester(10,20);

Which can be used to replace / missing constructor / so that the object t is correctly created?

Answers

Answer:

Explanation:

The following constructor needs to be added to the code so that the object called t can be created correctly...

public Tester(int arg1, int arg2) {

    num1 = arg1;

    num2 = arg2;

}

This basic constructor will allow the object to be created correctly and will take the two arguments passed to the object and apply them to the private int variables in the class. The question does not state what exactly the Tester constructor is supposed to accomplish so this is the basic format of what it needs to do for the object to be created correctly.

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source. Nested lists The “*” operator List slices The “+=” operator A list filter A list operation that is legal but does the "wrong" thing, not what the programmer expects Provide the Python code and output for your program and all your examples.

Answers

Lists are used in Python to hold multiple values in one variable

(a) Nested list

A nested list is simply a list of list; i.e. a list that contains another list.

It is also called a 2 dimensional list.

An example is:

nested_list = [[ 1, 2, 3, 4]  , [ 5, 6, 7]]

(b) The “*” operator

The "*" operator is used to calculate the product of numerical values.

An example is:

num1 = num2 * num3

List slices

This is used to get some parts of a list; it is done using the ":" sign

Take for instance, you want to get the elements from the 3rd to the 5th index of a list

An example is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

secondList = firstList[2:5]

The “+=” operator

This is used to add and assign values to variables

An example is:

num1 = 5

num2 = 3

num2 += num1

A list filter

This is used to return some elements of a list based on certain condition called filter.

An example that prints the even elements of a list is:

firstList = [1, 2 ,3, 4, 5, 6, 7]

print(list(filter(lambda x: x % 2 == 0, firstList)))

A valid but wrong list operation

The following operation is to return a single list, but instead it returns as many lists as possible

def oneList(x, myList=[]):

   myList.append(x)

   print(myList)

oneList(3)

oneList(4)

The scope of a variable declared inside of a function is:a) Local - within that function

b) Within that file only

c) global

Answers

Answer:

The correct answer for the given question is option(a) i.e Local - within that function.

Explanation:

The variable which is declared inside any function are called as local variable The scope and lifetime of local variable is inside that block or function only.

They cannot access outside the function.

Following are the example of local variable

#include <stdio.h> // header file

void fun(); // function prototype

int main()// main function

{

fun(); //calling function

print("%d",t); // it gives error because t is local variable cannot access in main function

return 0;

}

void fun()

{

int t=9;// local variable

printf("t is local variable which value is:");

printf("%d",t);

}

As we seen that t cannot access outside the function .So correct answer is option(a)

Final answer:

The scope of a variable declared inside of a function is local - within that function. This prevents naming conflicts and ensures control over where a variable can be changed.

Explanation:

The scope of a variable declared inside of a function is typically local to that function. This means that it can only be accessed and manipulated within the function it is declared. It is not visible or accessible from outside of the function or elsewhere in the program file, hence options b) and c) are incorrect. This principle is fundamental in programming languages such as JavaScript, C++, Python, etc., and it is designed this way to prevent naming conflicts and provide control over where a variable can be changed.

NAT ________. allows a firm to have more internal IP addresses provides some security both allows a firm to have more internal IP addresses and provides some security neither allows a firm to have more internal IP addresses nor provides some security

Answers

Answer:

NAT provides some security but allows a firm to have more internal IP addresses

Explanation:

NAT ( network address translation) this is a process where a  network system usually a firewall  assigns a public IP address to an internal computer used in a private network. it limits the number of public IP address a company operating a private network for its computer can have and this is very economical also limits the exposure of the company's private network of computers. the computers can access information within the private network using multiple IP addresses but it is safer to access external information using one public IP address

Write a python program that asks the user to enter a student's name and 8 numeric tests scores (out of 100 for each test). The name will be a local variable. The program should display a letter grade for each score, and the average test score, along with the student's name. There are 12 students in the class. Write the following functions in the program:
calc_average - this function should accept 8 test scores as arguments and return the average of the scores per student
determine_grade - this function should accept a test score average as an argument and return a letter grade for the score based on the following grading scale:
90-100 A
80-89 B
70-79 C
60-69 D
Below 60 F

Answers

In this exercise we have to use the computer language knowledge in python to write the code as:

the code is in the attached image.

In a more easy way we have that the code will be:

def calc_average(name):

  score = []

  sum = 0

  for j in range(8):

      inp = int(input("Test Score"+str(j+1)+": "))

      score.append(inp)

      sum = sum + inp

      if inp>=90 and inp<=100:

          print("A")

      elif inp>=80 and inp<90:

          print("B")

      elif inp>=70 and inp<80:

          print("C")

      elif inp>=60 and inp<70:

          print("D")

      else:

          print("F")

  avg = sum/8

  print("Result Details of "+name)

  print("Average Score: "+str(avg))

  return avg

def determine_grade(result):

  if float(result) >= 90.0 and float(result) <= 100.0:

      print("Letter Grade: A")

  elif float(result) >= 80.0 and float(result) <90.0:

      print("Letter Grade: B")

  elif float(result) >= 70.0 and float(result) < 80.0:

      print("Letter Grade: C")

  elif float(result) >= 60.0 and float(result) < 70.0:

      print("Letter Grade: D")

  else:

      print("Letter Grade: F")

  print(" ")

for i in range(2):

  name = input("Student Name: ")

  result = calc_average(name)

  determine_grade(result)

Answer:

The program doesn't make use of comments (See Explanation)

Also the source code is attached as image to enable you see the proper format and indexing of the source code

The program using python is as follows

def calc_average(name):

   score = []

   sum = 0

   for j in range(8):

       inp = int(input("Test Score"+str(j+1)+": "))

       score.append(inp)

       sum = sum + inp

       if inp>=90 and inp<=100:

           print("A")

       elif inp>=80 and inp<90:

           print("B")

       elif inp>=70 and inp<80:

           print("C")

       elif inp>=60 and inp<70:

           print("D")

       else:

           print("F")

   avg = sum/8

   print("Result Details of "+name)

   print("Average Score: "+str(avg))

   return avg

def determine_grade(result):

   if float(result) >= 90.0 and float(result) <= 100.0:

       print("Letter Grade: A")

   elif float(result) >= 80.0 and float(result) <90.0:

       print("Letter Grade: B")

   elif float(result) >= 70.0 and float(result) < 80.0:

       print("Letter Grade: C")

   elif float(result) >= 60.0 and float(result) < 70.0:

       print("Letter Grade: D")

   else:

       print("Letter Grade: F")

   print(" ")

for i in range(2):

   name = input("Student Name: ")

   result = calc_average(name)

   determine_grade(result)

Explanation:

def calc_average(name):  -> Declares the function calc_average(name); It accepts local variable name from the main function

   score = []

-> Initialize an empty list to hold test scores

   sum = 0

-> Initialize sum of scores to 0

   for j in range(8):

-> Iterate from test score 1 to 8

       inp = int(input("Test Score"+str(j+1)+": "))

-> This line accepts test score from the user

       score.append(inp)

-> The user input is then saved in a lisy

       sum = sum + inp

-> Add test scores

The following lines determine the letter grade of each test score      

if inp>=90 and inp<=100:

           print("A")

---

      else:

           print("F")

   avg = sum/8  -> Calculate average of the test score

The next two lines prints the name and average test score of the student

   print("Result Details of "+name)

   print("Average Score: "+str(avg))

   return avg

-> This line returns average to the main method

The following is the determine_grade method; it takes it parameter from the main method and it determines the letter grade depending on the calculated average

def determine_grade(result):

   if float(result) >= 90.0 and float(result) <= 100.0:

       print("Letter Grade: A")

   elif float(result) >= 80.0 and float(result) <90.0:

       print("Letter Grade: B")

   elif float(result) >= 70.0 and float(result) < 80.0:

       print("Letter Grade: C")

   elif float(result) >= 60.0 and float(result) < 70.0:

       print("Letter Grade: D")

   else:

       print("Letter Grade: F")

   print(" ")

for i in range(2):

-> This is the main method

   name = input("Student Name: ")  -> A local variable stores name of the student

   result = calc_average(name)  -> store average of scores in variable results

   determine_grade(result)-> Call the determine_grade function
