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.

Explanation:
public class Card
{
String Suit;
int value;
public Card(int value, String Suit) {
self.value = value;
// Check Suits value
if ((Suit == "hearts") || (Suit == "spades") || (Suit == "clubs") || (Suit == "diamonds"))
self.Suit = Suit;
else {
Suit = "none";
throw new IllegalArgumentException("no card of this type exists.");
}
}
public String getSuit() {
return Suit;
}
public int getValue() {
return value;
}
public void print() {
System.out.println("%d of %s", value, Suit);
}
}

Vehicle maintenance is important because without them the vehicle would not function properly and could be a safety hazard. Vehicle safety is important because without it we could end up seriously injured or even killed, vehicles can be very dangerous if handled irresponsible and the proper safety methods are not used.<span />
