Which is the most correct option regarding subnet masks?

Answer:

following are the program to the given question:

Program:

x = 0#defining an integer variable that holds a value

if x < 0:#defining if that checks x less than 0

   print("This number ",  x, " is negative.")#print value with the message

else:#defining else block

   if x > 0:#defining if that checks x value greater than 0

       print(x, " is positive")#print value with message

   else:#defining else block

       print(x, " is 0")#print value with message

if x < 0:#defining another if that checks x less than 0

   print("This number ",  x, " is negative.")

elif (x > 0):#defining elif block that check x value greater than 0

   print(x, " is positive")#print value with message

else:#defining else block

   print(x, " is 0")#print value with message

Output:

Please find the attachment file.

Explanation:

In this code, an x variable is defined which holds a value that is "0", in the next step nested conditional statement has used that checks the x variable value and uses the print method that compares the value and prints its value with the message.

In another conditional statement, it uses if that checks x value less than 0 and print value with the negative message.

In the elif block, it checks x value that is greater than 0 and prints the value with the positive message, and in the else block it will print the message that is 0.

Explanation:

The following code is written in Javascript and is a function called primes that takes in a single parameter as an int variable named n. An array is created and looped through checking which one is prime. If So it, changes the value to true, otherwise it changes it to false. Then it creates another array that loops through the boolArray and grabs the actual numberical value of all the prime numbers. A test case for n=150 is created and the output can be seen in the image below highlighted in red.

function primes(n) {

   //Boolean Array to check which numbers from 1 to n are prime

   const boolArr = new Array(n + 1);

   boolArr.fill(true);

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

double average(double s1, double s2, double s3, double s4, double s5){

   double avg = (s1 + s2 + s3 + s4 + s5)/5;

   return avg;}

char lGrade(double score){

   char grade;

   if(score>= 90 && score <= 100){ grade ='A'; }

   else if(score>= 80 && score <= 89){ grade ='B'; }

   else if(score>= 70 && score <= 79){ grade ='C'; }

   else if(score>= 60 && score <= 69){ grade ='D'; }

   else if(score < 60){ grade ='F'; }

   return grade;}

int main(){

   double s1,s2,s3,s4,s5;

   cin>>s1>>s2>>s3>>s4>>s5;

   double avg = average(s1,s2,s3,s4,s5);

   cout<<s1<<" "<<lGrade(s1)<<endl;

   cout<<s2<<" "<<lGrade(s2)<<endl;

   cout<<s3<<" "<<lGrade(s3)<<endl;

   cout<<s4<<" "<<lGrade(s4)<<endl;

   cout<<s5<<" "<<lGrade(s5)<<endl;

   cout<<avg<<" "<<lGrade(avg)<<endl;

   return 0;}

Explanation:

The three functions to include in the program are not stated; so, I used the following functions in the program

1. The main function

2. average function

3. Letter grade function

The average function begins here

double average(double s1, double s2, double s3, double s4, double s5){

This calculates the average

   double avg = (s1 + s2 + s3 + s4 + s5)/5;

This returns the calculated average

   return avg;}

The letter grade function begins here

char lGrade(double score){

This declares the grade

   char grade;

If score is between 90 and 100 (inclusive), grade is A

   if(score>= 90 && score <= 100){ grade ='A'; }

If score is between 00 and 89 (inclusive), grade is B

   else if(score>= 80 && score <= 89){ grade ='B'; }

If score is between 70 and 79 (inclusive), grade is C

   else if(score>= 70 && score <= 79){ grade ='C'; }

If score is between 60 and 69 (inclusive), grade is D

   else if(score>= 60 && score <= 69){ grade ='D'; }

If score is less than 60, grade is F

   else if(score < 60){ grade ='F'; }

This returns the calculated grade

   return grade;}

The main begins here

int main(){

This declares the 5 scores

   double s1,s2,s3,s4,s5;

This gets input for the 5 scores

   cin>>s1>>s2>>s3>>s4>>s5;

This calls the average function for average

   double avg = average(s1,s2,s3,s4,s5);

This calls the letter grade function for the 5 scores

   cout<<s1<<" "<<lGrade(s1)<<endl;

   cout<<s2<<" "<<lGrade(s2)<<endl;

   cout<<s3<<" "<<lGrade(s3)<<endl;

   cout<<s4<<" "<<lGrade(s4)<<endl;

   cout<<s5<<" "<<lGrade(s5)<<endl;

This calls the average function for the average

   cout<<avg<<" "<<lGrade(avg)<<endl;

       Scanner in = new Scanner(System.in);

       System.out.print("Enter Car Make: ");

       String make1 = in.next();

       System.out.print("Enter Car Model: ");

       String model1 = in.next();

       System.out.print("Enter Car Year: ");

       int year1 = in.nextInt();

       System.out.print("Enter Car Make: ");

       String make2 = in.next();

       System.out.print("Enter Car Model: ");

       String model2 = in.next();

       System.out.print("Enter Car Year: ");

       int year2 = in.nextInt();

       System.out.print("Enter Car Make: ");

       String make3 = in.next();

       System.out.print("Enter Car Model: ");

       String model3 = in.next();

       System.out.print("Enter Car Year: ");

       int year3 = in.nextInt();

       Cars car1 = new Cars(make1, model1, year1);

       Cars car2 = new Cars(make2, model2, year2);

       Cars car3 = new Cars(make3, model3, year3);

       car1.show();

       car2.show();

       car3.show();

   }

}

class Cars {

   String makes, models;

   int years;

   public Cars(String makes, String models, int years) {

       this.makes = makes;

       this.models = models;

Algorithm :

1.START

2. sum=0 ; n=1 ; length = 1

3. sum = sum + n

4. n = n + 2

5. length = length + 1

6. Repeat steps 3, 4 and 5 until n <= 99

7. mean = sum / length

8. print(mean)

Explanation:

Sum initializes the addition of the odd numbers

n starts from 1 and increments by 2, this means every n value is a odd number

The condition n <= 99 ensures the loop isn't above range isn't above 100 ;

The length variable, counts the number of odd values

Mean is obtained by dividing the SUM by the number of odd values.
