Question 8 of 25

Using the program below, explain what the output will be at LINE A. 1 #include 2#include 3#include 4 5 int value - 128; 6 7 int

slega [8]

Answer:

This is the complete correct program:

#include <stdio.h>

#include<sys/types.h>

#include<unistd.h>

int value = 128;

int main()

{

pid_t pid;

pid=fork();

if (pid==0) /* child process */

{

value +=8;

return 0; }

else if (pid > 0) {/* parent process */

wait (NULL);

printf ("PARENT: value =%d\n" ,value); /* LINEA */

return 0;

}

The output of the LINE A is:

PARENT: value = 128

Explanation:

The fork() function used in the program creates a new process and this process is the child process. The child process is same as the original process having its own address space or memory.

In the child process the value of pid is 0. So the if condition checks if pid==0. Then the child process adds 8 to the value of its variable according to the following statement

value +=8;

Now the original process has value = 128. In else if part the parents process has the value of pid greater than zero and this portion of the program is of the parent process :

else if (pid > 0)

{ wait (NULL);

printf ("PARENT: value =%d\n" ,value);

return 0; }

So the value 128 is printed at the end in the output.

wait(NULL) is used to wait for the child process to terminate so the parent process waits untill child process completes.

So the conclusion is that even if the value of the variable pid is changed in the child process but it will not affect the value in the variable of the parent process.

int x = scan.nextInt();

System.out.println("Here are the digits:");

System.out.println(x/100);

System.out.println((x/10)%10); //Just divide the result by 10 and find the remainder

System.out.println(x%10);

}

//Or, you can do that way:

import java.util.Scanner;

public class U1_L5_Activity_One {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.print("Please enter a two digit number: ");

String[] x = scan.nextLine().split(""); //We need it to be a string array, to split the values after "", that is, after each symbol(number)

System.out.println("Here are the digits:");

for(int i = 0; i<x.length; i++) {

System.out.println(Integer.parseInt(x[i])); //Converting the string into int, as you want

You might propose guest worker program for your country if you wanted to hire a large number of manual laborers from neighboring countries to build a large dam or canal, with the understanding that they would not be granted any other privileges or legal status in your country, after the project is finished.

<h3>What is guest worker program?</h3>

In the absence of a ready supply of replacement workers, guest worker programs enable foreign workers to live and work temporarily in a host nation.
For temporary employment lasting less than a year, the United States now offers two guest worker programs: the H-2A program for temporary agricultural work and the H-2B program for temporary non-agricultural work.

Guest workers will be eligible for all federal programs, including Social Security and Medicare, if they are granted green cards. Additionally, low-skilled, low-income guest workers bring along their spouses and kids, who are enrolled in local schools and qualify for a variety of state benefits.
