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.
Answer:
The correct answer to the following question will be "Secure".
Explanation:
This file includes information about the rights of verification and authorization.
- It will be used primarily for monitoring the use of authorization schemes.
- It holds all communications related to safety like faults in encryption.
- This also monitors sshd logins, logins of SSH, as well as other system security resources daemon-logged failures.
So, it's the right answer.

A command you would use to perform a reverse lookup of the IP address 10.0.0.3 on a Linux system: dig -x 10.0.0.3.
<h3>What is a Linux command?</h3>
A Linux command can be defined as a software program that is designed and developed to run on the command line, in order to enable an administrator (end user) of a Linux network perform both basic and advanced tasks by only entering a line of text.
<h3>What is IP address?</h3>
IP address is an abbreviation for Internet protocol address and it can be defined as a unique set of numbers that are assigned to a computer, website or other network devices, in order to successfully differentiate them from one another in an active network system.
In Computer Networking, a command which an administrator (end user) would use to perform a reverse lookup of the IP address 10.0.0.3 on a Linux system is dig -x 10.0.0.3.
