Explanation:

An interface is declared as follows:

interface interface_name{          

   member fields

   methods  }  

So the Sports interface is declared as:

interface Sports{   }  

You can also write its as:

public interface Sports { }

Now this interface has a method jump that has no parameters and does not return anything. So it is defined as:

void jump();

You can also write it as:

public void jump();

Notice that it has a void keyword which means it does not return anything and empty round brackets show that it has no parameters. Lets add this to the Sports interface:

interface Sports{  

void jump();   }    

You can write it as:

public interface Sports {

  public void void jump();  }

Next, this Sports interface has a method throw that has one parameter called distance and is an integer and does not return anything. So it is defined as:

throw(int distance);

You can also write it as:

  public void throw(int distance)

Notice that this function has a void return type and one int type parameter distance. Now lets add this to Sports interface:

interface Sports{        

   void jump();  

   void throw(int distance);   }

This can also be written as:

public interface Sports {

 public  void jump();  

   public void throw(int distance); }

Next, the class header for a class named Football that would use this interface is as follows:

class Football implements Sports{  }

You can use the methods of Sports in Football too. So the complete interface with class Football becomes:

interface Sports{  

void jump();  

void throw(int distance);

}  

class Football implements Sports{  

public void print(){

}  

public void throw(int distance) {

}

Next we have a parent class called GrandParents. So child class called GrandChild that would be a direct child of the class GrandParents is:

class GrandChild extends GrandParents {   }

Basic syntax of a parent class and its child class is:

class child_class_name extends parent_class_name

{  

  //member fields and methods

}

Answer:

Here is the program:

#include <stdio.h>  //to use input output functions

#include <unistd.h> //provides access to the POSIX OS API

int main() { //start of main function

   int x;  //declare an int type variable x

   x = 100;  // sets the value of x to 100

   int r = fork();  //calls fork() method to create a new process. r is used to store the value returned by fork()

   if(r<0){  //if fork() returns -1 this means no child process is created

           fprintf(stderr, "Error");}     //prints the error message using standard error stream

  else if (r == 0)     {  //if fork returns 0 this means child process is created

       printf("This is child process\n");  //prints this message

       x = 150;  //changes value of x to 150

       printf("Value of x in child process: %d\n", x);     }  //prints the new value of x in child process

   else      {

       printf("This is parent process\n");  //if r>0

       x = 200;  //changes value of x to 200

       printf("Value of x in parent process: %d\n", x);     }  } //prints the new value of x in parent process

Explanation:

The program is well explained in the comments added to each line of the code. The answers to the rest of the questions are as follows:

What value is the variable in the child process?

The variable x is set to 150 in child process. So the printf() statement displays 150 on the screen.

What happens to the variable when both the child and parent change the value of x?

fork() creates a copy of parent process. The child and parent processes have their own private address space. Therefore none of the both processes cannot interfere in each other's memory. The both maintain their own copy of variables. So, when parent process prints the value 200 and child process prints the value 150.

In order to see which is the final value of x, lets write a statement outside all of the if else statements:

  printf("Final value of x: %d\n", x);

This line is displayed after the value of parent class i.e. 200 is printed on the screen and it shows:

Final value of x: 200

Note this is the value of x in parent process

However the same line displayed after the value of child class i.e. 150 is printed on the screen and it shows:

Final value of x: 150

The screenshot of the program along with the output is attached.

In this exercise we have to use the knowledge of computational language in C code to describe a code, like this:

The code can be found in the attached image.

To make it easier the code can be found below as:

#include <stdio.h>

#include <unistd.h>

int main() {

  int x;

  x = 100;

  int r = fork();

  if(r<0){  

          fprintf(stderr, "Error");}  

 else if (r == 0)     {

      printf("This is child process\n");

      x = 150;

      printf("Value of x in child process: %d\n", x);     }

  else      {

      printf("This is parent process\n");

      x = 200;  

      printf("Value of x in parent process: %d\n", x);     }  }

Answer:

Here is the program:

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

#include <string>  // to use functions to manipulate strings

using namespace std;  //to identify objects cin cout

void function(string prefix, unsigned int levels){  // function that takes two parameters, a string, using the string class and levels an unsigned integer

   if (levels == 0) {  //if number of levels is equal to 0

       cout << prefix << endl;  //displays the value of prefix

       return;    }  

  for (int i = 1; i <=9 ; i++){  //iterates 1 through 9 times

       string sections = (levels == 1 ? "" : ".");  //if the number of levels is equal to 1 then empty space in sections variable otherwise stores a dot

       string output = prefix +  std::to_string(i) + sections;   // displays the string prefix followed by the section numbers. Here to_string is used to convert integer to string

       function(output, levels - 1);   } }   //calls function by passing the resultant string and levels-1  recursively to print the string prefix followed by section numbers

int main() {  // start of main function

   int level = 2;  //determines the number of levels

   function("BOX", level);  } //calls function by passing the string prefix and level value

Explanation:

The program has a function named function() that takes two parameters, prefix (a string, using the string class from ) and levels (an unsigned integer). The function prints the string prefix followed by "section numbers" of the form 1.1., 1.2., 1.3., and so on. The levels argument determines how many levels the section numbers have. If the value of levels is 0 means there is 0 level then the value of prefix is printed. The for loop iterates '1' through '9' times for number of digits in each level. If the number of levels is 1 then space is printed otherwise a dot is printed. The function() calls itself recursively to print the prefix string followed by section numbers.

Let us suppose that prefix = "BOX" and level = 1

If level = 1 then the loop for (int i = 1; i <=9 ; i++) works as follows:

At first iteration:

i = 1

i <=9 is true because value of i is 1

string sections = (levels == 1 ? "" : "."); this statement checks if the levels is equal to 1. It is true so empty space is stored in sections variable so,

sections = ""

Next, string output = prefix +  std::to_string(i) + sections; statement has prefix i.e BOX plus value of i which is 1 and this int value is converted to string by to_string() method plus sections has an empty space. So this statement becomes

string output = BOX + 1  

So this concatenates BOX with 1 hence output becomes:

output = BOX1

At second iteration:

i = 2

i <=9 is true because value of i is 2

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix +  std::to_string(i) + sections; statement becomes

string output = BOX + 2  

So this concatenates BOX with 1 hence output becomes:

output = BOX2

At third iteration:

i = 3

i <=9 is true because value of i is 3

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix +  std::to_string(i) + sections; statement becomes

string output = BOX + 3  

So this concatenates BOX with 1 hence output becomes:

output = BOX3

Now at each iteration the prefix string BOX is concatenated and printed along with the value of i. So at last iteration:

At last iteration:

i = 9

i ==9 is true because value of i is 9

string sections = (levels == 1 ? "" : "."); is true so

sections = ""

Next, string output = prefix +  std::to_string(i) + sections; statement becomes

string output = BOX + 9  

So this concatenates BOX with 1 hence output becomes:

output = BOX9

After this the loop breaks at i = 10 because the condition i<=9 becomes false. So the output of the entire program is:

BOX1                                                                                                                                          BOX2                                                                                                                                          BOX3                                                                                                                                          BOX4                                                                                                                                          BOX5                                                                                                                                          BOX6                                                                                                                                          BOX7                                                                                                                                          BOX8                                                                                                                                          BOX9

It is important for you as a student to recognize that the online classroom is in fact a classroom, and certain behaviors are expected when you communicate with both your peers and your instructors. These guidelines for online behavior and interaction are known as “netiquette”.

So, the correct option of this question is: students should practice netiquette in an online course when they are participating in an online discussion board. Because the discussion board is opened by the instructor/tutor, he constantly looking for student behavior throughout the discussion. so, students should use netiquette practice during the discussion in the online class.

However, other options are not correct because, in these options, there is not the presence of teacher/instructor. And, also noted that netiquette is practiced in online class by the student.

Answer:

Follows are the solution to this question:  

Explanation:

In the previous algorithm has also been fine yet un optimal and also gives O(n^2) computation time, that is is very powerful. It is a proposed algorithm, that has been arriving because its method has also been defined, its sorting provides the O( nlogn), which is much better than the last time complexity.  

When did I consider repeat figures, it is another aspect to note at the same figures arise as figures are ordered, for instance, the number is 1, 2, 1, 3, 2, 1, 3.  It becomes such as these number once sorted  1 , 1 , 1, 2 , 2 , 3 , 3.  

The smaller number 1, that's also 3 times combined in the second-largest amount, which is 2 times, but instead number 3, that's 2 times together consequently, with one pass in series, they can conveniently check the amount of duplicate.

It is a particular characteristic that appears 2 or more times, so it gets the same increases and amount for multiple copies when it sorted, and search for a specific transaction if it is equal with the original weeks.  If there is indeed a problem we have an amount more than 2 times for the same amount we need additional iterations.  

Therefore, the second 1 method fits it's very first 1 and its increase in multiple copies, however, the third 1 is the same for the second 1, so the amount of double for step 1 was already increased again so the same number also has an element following.  To remove this problem, a hashmap keeps track as a number, which crossed 1 time must be initialized the algorithm and doesn't search for amount again.

The algorithm functions as follows:  

1.initialize a hashmap which defaults to 0.  

2.Now sorted array with the second position element.  

3.Check if the element hashmap value is 0 as well as the previous variable has the same value.  

4. Increase the number of multiple copies and fill out hazmap element to 1 if both conditions and AND conditions become valid.  

5. if  the element and move to the next item if the state of AND is wrong.  

6. go to 3 and take the same steps to the end of the array.
