People are concerned about losing their jobs. The industrial revolution introduced machines that removed the need for humans to be involved in highly repetitive tasks.
Answer:
Option C. The path from start to finish that passes through all the tasks that are critical to completing the project in the shortest amount of time
is the correct answer.
Explanation:
- Critical path is the term used in Project management.
- It can be known by determining the longest stretch for dependent activities and the time required for them to complete.
- A method known as "critical path method" is used for Project modelling.
- All types of projects including aerospace, software projects, engineering or plant maintenance need Critical method analysis for the modeling of project and estimation.

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.
