Answer:

Written in Python

print("Enter the first 9 digits: ")

d1 = int(input())

d2 = int(input())

d3 = int(input())

d4 = int(input())

d5 = int(input())

d6 = int(input())

d7 = int(input())

d8 = int(input())

d9 = int(input())

d10 = (d1 * 1+ d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5 + d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9)%11

if d10 == 10:

                                   print(str(d1)+str(d2)+str(d3)+str(d4)+str(d5)+str(d6)+str(d7)+str(d8)+str(d9)+"X")

else:

                                   print(str(d1)+str(d2)+str(d3)+str(d4)+str(d5)+str(d6)+str(d7)+str(d8)+str(d9)+str(d10))

Explanation:

This line prompts user for input

print("Enter the first 9 digits: ")

The next 9 line gets the first 9 ISBN digits

d1 = int(input())

d2 = int(input())

d3 = int(input())

d4 = int(input())

d5 = int(input())

d6 = int(input())

d7 = int(input())

d8 = int(input())

d9 = int(input())

This calculates the checksum

d10 = (d1 * 1+ d2 * 2 + d3 * 3 + d4 * 4 + d5 * 5 + d6 * 6 + d7 * 7 + d8 * 8 + d9 * 9)%11

The if condition prints the ISBN number by replacing the last digit with X if the checksum is 10 else it appends the original digits

if d10 == 10:

                                   print(str(d1)+str(d2)+str(d3)+str(d4)+str(d5)+str(d6)+str(d7)+str(d8)+str(d9)+"X")

else:

                                   print(str(d1)+str(d2)+str(d3)+str(d4)+str(d5)+str(d6)+str(d7)+str(d8)+str(d9)+str(d10))

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

    int n;

    double side;

    char choice;

    while(true){

        System.out.print("Enter the number of sides: ");

     n = input.nextInt();

     System.out.print("Enter the side of a regular polygon: ");

     side = input.nextDouble();

     System.out.println("Area is: " + area(n, side));

     System.out.print("Do you want to continue(y/n): ");

     choice = input.next().charAt(0);

     if(choice == 'n')

         break;

    }

}

public static double area(int n, double side){

    double area = (n * Math.pow(side, 2) / (4 * Math.tan(Math.PI / n)));

    return area;

}

}

Explanation:

Create a function named area that takes two parameters, n and side

Calculate the area using the given formula

Return the area

In the main:

Create an indefinite while loop. Inside the loop:

Ask the user to enter the n and side

Call the area() function passing the n and side as parameters and print the result

Ask the user to continue or not. If the user enters "n", stop the loop

Answer:

Here is the Python program:

import math #import math to use mathematical functions

height = float(input("Enter wall height (feet): ")) #prompts user to enter wall height and store it in float type variable height

width = float(input("Enter wall width (feet): ")) #prompts user to enter wall width and store it in float type variable width

area = height *width #computes wall area

print('Wall area: {} square feet'.format(round(area))) #displays wall area using round method that returns a floating-point number rounded

sqftPerGallon = 350 #sets sqftPerGallon to 350

paintNeeded = area/ sqftPerGallon #computes needed paint

print("Paint needed: {:.2f} gallons".format(paintNeeded)) #displays computed paint needed up to 2 decimal places

cansNeeded = int(math.ceil(paintNeeded)) #computes needed cans rounding the paintNeeded up to nearest integer using math.ceil

print("Cans needed: {} can(s)".format(cansNeeded)) #displays computed cans needed

colorCostDict = {'red': 35, 'blue': 25, 'green': 23} #creates a dictionary of colors with colors as key and cost as values

color = input("Choose a color to paint the wall: ") #prompts user to enter a color

if color in colorCostDict: #if the chosen color is present in the dictionary

    colorCost = colorCostDict.get(color) #then get the color cost from dictionary and stores it into colorCost using get method that returns the value(cost) of the item with the specified key(color)

    cost = cansNeeded * colorCost #computes the cost of purchasing paint of specified color per cansNeeded

  print("Cost of purchasing {} paint: ${}".format(color,colorCostDict[color])) #displays the real cost of the chosen color paint

print("Cost of purchasing {} paint per {} gallon can(s): ${}".format(color,cansNeeded, cost)) #displays the cost of chosen color paint per cans needed.

Explanation:

The program first prompts the user to enter height and width. Lets say user enter 20 as height and 50 as width so the program becomes:

Wall area computed as:

area = height *width

area = 20 * 50

area = 1000

Hence the output of this part is:

Wall area: 1000 square feet                                                                                                                     Next program computes paint needed as:

paintNeeded = area/ sqftPerGallon

Since sqftPerGallon = 350 and area= 1000

paintNeeded = 1000 / 350

paintNeeded = 2.86

Hence the output of this part is:

Paint needed: 2.86 gallons

Next program computes cans needed as:      

cansNeeded = int(math.ceil(paintNeeded))

This rounds the computed value of paintNeeded i.e. 2.86 up to nearest integer using math.ceil so,

cansNeeded = 3                                                                  

Hence the output of this part is:

Cans needed: 3 can(s)                                                                                                                            Next program prompts user to choose a color to paint the wall

Lets say user chooses 'blue'

So the program get the cost corresponding to blue color and multiplies this cost to cans needed to compute the cost of purchasing blue paint per gallon cans. So

cost = cansNeeded * colorCost

cost = 3 * 25

cost = 75

So the output of this part is:

Cost of purchasing blue paint per 3 gallon can(s): $75                                                                                        The screenshot of the program along with its output is attached.

Answer: i dont now

Explanation:

Answer:

Here is the JAVA program :

import javax.swing.JOptionPane;   //to use JOptionPane  

public class Main {   //class name

public static void main(String[] args) { //start of main method

   int ECount= 0;   //counts number of upper case E

   int eCount= 0;  //counts number of lower case e

   String sentence;   //stores input sentence string

sentence = JOptionPane.showInputDialog(null, "Type a sentence (type stop to exit)");  //uses showInputDialog method to display a dialog box which prompts user to enter a sentence

 int length = sentence.length();  //stores the length of the sentence

 while (!sentence.equalsIgnoreCase("stop"))  //the loop continues to execute until the user types stop

{ for (int i = 0; i < length; i++) { //loops through the sentence

             if (sentence.charAt(i) == 'E')  //if the character is an uppercase E

                  ECount += 1;  //adds 1 to the count of Ecount

             if (sentence.charAt(i) == 'e')  //if the character in a sentence is lowercase e

                  eCount += 1;}  //adds 1 to the count of lower case e

JOptionPane.showMessageDialog(null, "There are " + ECount + " number of E's and " + eCount + "  number of e's in " +sentence);   //displays the number of times uppercase and lowercase (E and e) occur in sentence

sentence = JOptionPane.showInputDialog(null, "Type a sentence (type stop to exit");  //prompts user to enter the next sentence

length = sentence.length();  //stores the length of sentence at each iteration of while loop until user enters stop

eCount=0;  //resets the counter of lowercase e

ECount=0;  } } } //resets the counter of uppercase e

Explanation:

The program uses showInputDialog() method that displays a dialog box on output screen. This dialog box prompts the user to enter a string (sentence) Suppose user enters "Evergreen" as input sentence so

sentence = "Evergreen"

Next the length of this string is computed using length() method and stored in length variable. So

length = sentence.length();

length = 9

The for loop iterates through this input sentence until the variable i is less than length i.e. 9

At first iteration

if (sentence.charAt(i) == 'E') becomes

if (sentence.charAt(0) == 'E')

Here charAt() method is used which returns the character at the specified index i. This if condition is true because the character at 0-th index (first character) of the sentence Evergreen is E. So ECount += 1; statement adds 1 to the count of upper case E so

ECount = 1

At second iteration:

if (sentence.charAt(1) == 'E')

this condition is false because the character at 1st index of sentence is 'v' which not an upper case E so the program moves to next if condition if (sentence.charAt(i) == 'e') which is also false because the character is not a lower case e either.

At third iteration:

if (sentence.charAt(2) == 'E')

this condition is false because the character at 2nd index of sentence is 'e' which not an upper case E so the program moves to next if condition if (sentence.charAt(i) == 'e') which is true because the character is a lower case e. So the statement eCount += 1; executes which adds 1 to the count of e.

eCount = 1

So at each iteration the sentence is checked for an upper case E and lower case e. After the loop breaks, the program moves to the statement:

JOptionPane.showMessageDialog(null, "There are " + ECount + " number of E's and " + eCount + "  number of e's in " +sentence);

which displays the number of uppercase E and lower case e in a message dialog box. So the output is:

There are 1 number of E's and 3 number of e's in Evergreen.

Then because of while loop user is prompted again to enter a sentence until the user enters "stop". Now the user can enter Stop, StOp, STOp etc. So equalsIgnoreCase method is used to cover all upper/lower case possibilities of the word "stop".

The screenshot of the program and its output is attached.

Explanation:

Since your indentation can not be understand what you give us, please try to do it as you see in the answer part.

Although it seems that this is a part of the code, it is normal that you get errors. However, since you keep track of the variables, it is better to initialize the variables that will keep the counts. Since initially, they are 0, you may set them as 0. Also, if you assign the values to the scores, probably you would not get any error. This way, you may test your code as I did.

Other than these, in the else part you do not need to write "score1=score2", because if score1 is not greater than score2 and if score2 is not greater than score1, this already implies that they are equal

Answer:

D

Explanation:

Answer:

Here is the C++ program:

#include <iostream>  //to use input output functions

#include <cstring>  // used to manipulate c strings

using namespace std;  //to identify objects cin cout

const int SIZE = 20;  //fixes constant size for firstName, middleName and lastName arrays

const int FULL_SIZE = 60;  //constant size for fullName array

int main() {  //start of main method

  char firstName[SIZE]; //declares a char type array to hold first name

  char middleName[SIZE];//declares a char type array to hold middle name

  char lastName[SIZE]; //declares a char type array to hold last name

  char fullName[FULL_SIZE]; //declares a char type array to hold full name

  cout << "Enter first name: ";  //prompts user to enter first name

  cin>>firstName;  //reads first name from user, stores it in firstName char array

  cout << "Enter middle name: ";  //prompts user to enter middle name

  cin>>middleName;  //reads middle name from user, stores it in middleName char array

  cout << "Enter last name: ";  //prompts user to enter last name

  cin>>lastName;  //reads last name from user, stores it in lastName array

  strcpy(fullName, lastName);  //copies last name from lastName to fullName array using strcpy method which copies a character string from source to destination

  strcat(fullName, ", ");  //appends comma "," and empty space " " after last name in fullName using strcat method which appends a string at the end of another string

  strcat(fullName, firstName);  //appends first name stored in firstName to the last of fullName

  strcat(fullName, " ");  //appends an empty space to fullName

  strcat(fullName, middleName);  //appends middle name stored in middleName char array to the fullName char array

  cout <<"Full name is:\n"<<fullName<< endl; } //displays the full name

Explanation:

I will explain the program with an example inshaAllah

Lets say user enters Carol as first name, Lynn as middle and Smith as last name. So firstName char array contains Carol, middleName char array contains Lynn and lastName char array contains Smith.

Next the fullName array is declared to store Carol Lynn and Smith in a specific format:

strcpy(fullName, lastName);

This copies lastName to fullName which means fullName now contains Smith.

  strcat(fullName, ", ");

This appends comma and an empty space to fullName which means fullName now contains Smith with a comma and empty space i.e. Smith,

strcat(fullName, firstName);

This appends firstName to fullName which means Carol is appended to fullName which now contains Smith, Carol

  strcat(fullName, " ");

This appends an empty space to fullName which means fullName now contains Smith, Carol with an empty space i.e. Smith, Carol

 strcat(fullName, middleName);

This appends middleName to fullName which means Lynn is appended to fullName which now contains Smith, Carol Lynn

Now    cout <<"Full name is:\n"<<fullName<< endl; prints the fullName so the output of this entire program is:

Full name is:

According to the Modern Language Association (MLA) guidelines, the correct line spacing for a document is double-spacing. This means that there should be a full blank line between each line of text in the document. Hence, option A is the correct answer.

Double spacing helps improve readability and makes it easier for readers to distinguish between different lines of text. It also allows for better legibility and makes it easier to add annotations or comments to the document.

It's important to note that the MLA guidelines may change over time, so it's always a good idea to consult the most recent edition of the MLA Handbook or check with your instructor or institution for any specific requirements regarding line spacing or formatting.

Hence, option A is the correct answer.
