Taking a suitable example in c language explain the of call by value and call by reference concepts.
Degger [83]

Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.

Explanation:

Some examples are:

call by value

#include <stdio.h>  

void swap(int, int);

int main()

{  int a = 10, b= 20;

 swap(a, b);

 printf("a: %d, b: %d\n", a, b);

}  

void swap(int c, int d)

{

 int t;

 t = c; c = d; d = t;

}  

OUTPUT

a: 10, b: 20

The value of a and b remain unchanged as the values are local

//call by reference

#include <stdio.h>

 void swap(int*, int*);

 int main()

{

 int a = 10, b = 20;

 swap(&a, &b);   //passing the address

 printf("a: %d, b: %d\n", a, b);

}

void swap(int *c, int *d)

{

 int t;

 t = *c; *c = *d; *d = t;

}

OUTPUT

a: 20, b: 10

due to dereferencing by the pointer the value  can be changed which is call by reference

List the three control problems associated with competingprocesses and briefly define each.
hjlf

Answer and explanation :

the three control problems associated with competing process are

  • MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
  • DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
  • STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing  then low priorities process have to wait for very long time this is called starvation

import java.util.ArrayList; // Needed for ArrayList class /** This program demonstrates how to store BankAccount objects in an A
slega [8]

Answer:

import java.util.ArrayList; // Needed for ArrayList class

/** This program demonstrates how to store BankAccount objects in an ArrayList. */

// Class ArrayListDemo6 is defined

public class ArrayListDemo6 {

// main method that begin program execution

public static void main(String[] args) {

// Create an ArrayList to hold BankAccount objects.

// The arraylist is called list

ArrayList list = new ArrayList();

// Add three BankAccount objects to the ArrayList.

list.add(new bankAccount(100.0)); list.add(new bankAccount(500.0)); list.add(new bankAccount(1500.0)); // Display each item using a for loop

for (int index = 0; index < array.size(); index++)

{ BankAccount account = list.get(index);

System.out.println("Account at index " + index + "\nBalance: " + account.getBalance());

}

}

}

Explanation:

The code is written in Java and more comments has been added to make it more explanatory.

The code snippet is a demonstration on Arraylist.

First Arraylist is imported. Then, ArrayListDemo6 class is defined. Then the main method which begin program execution.

Inside the main method, a new Arraylist is created called list.

Then we add three BankAccount object to the list.

Lastly, we use a for loop to display each added BankAccount object.

Which model states that the people and the environment for communication are constantly changing? A. linear B. interactive C. tr
In-s [12.5K]

The interactive model of communication states that the people and the environment for communication are constantly changing.

B. interactive

<u>Explanation:</u>

The world is a big place and you must have come across the infamous hearing, "Change is the only constant". Gradually, with the passage of time, the mindset of the people change over a certain topic for communication.

For instance, in old times, people did not prefer their children to have love marriages, in fact India has also seen honor killings to prevent love marriages. But now most portion of the society stands in favor of love marriages. People change, perspective change, and so does the perception and ideas.
