Answer:

B. blocking I/O

Explanation:

           Most of the input and output request placed  to the computer considers the blocking request. It means that the controls given cannot be returned to the given application until and unless the input/output is complete.

           Thus, blocking the input/output does not return till the input and output is complete.

            With a blocking I/O, the process is moved to a wait queue when the I/O request is made, and it moved backs to the ready queue as soon as the request is complete, thereby allowing the other processes to run in the meantime.

Thus (B) blocking I/O is the answer.

Write a C console application that will be used to determine if rectangular packages can fit inside one of a set of spheres. You
MatroZZZ [7]

Answer:

#include <cmath>

#include <iostream>

using namespace std;

int getSphereSize(double length, double breadth, double height) {

   double diagonal = sqrt(length * length + breadth * breadth + height * height);

   if (diagonal <= 4)

       return 4;

   if (diagonal <= 6)

       return 6;

   if (diagonal <= 8)

       return 8;

   if (diagonal <= 10)

       return 10;

   if (diagonal <= 12)

       return 12;

   return 0;

}

int main() {

   double length, breadth, height;

   int sphereCounts[5] = {0};

   int sphereSize;

   while (true) {

       // Get dimensions of the box

       cout << "Enter the dimensions of the box:\n";

       cout << "Length: ";

       cin >> length;

       cout << "Breadth: ";

       cin >> breadth;

       cout << "Height: ";

       cin >> height;

       if (length <= 0 || breadth <= 0 || height <= 0)

           break;

       sphereSize = getSphereSize(length, breadth, height);

       if (sphereSize == 0)

           cout << "The box cannot fit in any of the spheres";

       else

           cout << "The box can fit in the " << sphereSize << "-inch sphere";

       // Increment the counter

       if (sphereSize == 4)

           sphereCounts[0]++;

       else if (sphereSize == 6)

           sphereCounts[1]++;

       else if (sphereSize == 8)

           sphereCounts[2]++;

       else if (sphereSize == 10)

           sphereCounts[3]++;

       else if (sphereSize == 12)

           sphereCounts[4]++;

       cout << "\n\n";

   }

   cout << "\nNumber of 4-inch spheres: " << sphereCounts[0];

   cout << "\nNumber of 6-inch spheres: " << sphereCounts[1];

   cout << "\nNumber of 8-inch spheres: " << sphereCounts[2];

   cout << "\nNumber of 10-inch spheres: " << sphereCounts[3];

   cout << "\nNumber of 12-inch spheres: " << sphereCounts[4];

   cout << endl;

   return 0;

}

Explanation:

The "cmath" library is included in the c++ program. The getSphereSize function is used to return the sphere size the rectangle dimension can fit into. It program continuously prompts the user for the length, breadth, and height of the rectangle and passes the values to the getSphereSize function in the while but breaks if any or all of the variable value is zero.

The sizes of the sphere objects in inches are collected in an array of five integer values of zeros and are incremented by one for every match with a rectangle.

1.Write a Java program to solve the following problem using modularity. Write a method that rotates a one-dimensional array with
Westkost [7]

Answer:

Explanation:

The following code is written in Java and it asks the user for the size of the array. Then it randomly populates the array and prints it. Next, it rotates all the elements to the right by 1 and prints the new rotated array.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Random;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       Random r = new Random();

       Scanner in = new Scanner(System.in);

       System.out.println("Enter Size of the Array: ");

       int arraySize = in.nextInt();

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

       for (int x = 0; x < arraySize; x++) {

           myList.add(r.nextInt(15));

       }

       System.out.println("List Before Rotation : " + Arrays.toString(myList.toArray()));

       for (int i = 0; i < 1; i++) {

           int temp = myList.get(myList.size()-1);

           for (int j = myList.size()-1; j > 0; j--) {

               myList.set(j, myList.get(j - 1));

           }

           myList.set(0, temp);

       }

       System.out.println("List After Rotation :  " + Arrays.toString(myList.toArray()));

   }

}

Explain what will happen if we continue to use fossil fuels at the rate we are now and what impacts it will have on the planet.
Westkost [7]

Answer:

At the point when non-renewable energy sources are singed, they discharge carbon dioxide and other ozone depleting substances, which thusly trap heat in our air, making them the essential supporters of an Earth-wide temperature boost and environmental change. At the point when we consume oil, coal, and gas, we don't simply meet our vitality needs—we drive the current an unnatural weather change emergency also. Non-renewable energy sources produce huge amounts of carbon dioxide when consumed. Carbon discharges trap heat in the air and lead to environmental change.
