Q\ Assuming that the actual process ids of the parent and child processes are 50 and 75 respectively, what will be printed out at lines A, B, C, D, E, and F? Be sure to explain your answers.

int main() {

pid_t pid, pid1;

int data = 1500;

/* fork a child process */

pid = fork();

if (pid < 0) { /* error occurred */

fprintf(stderr,Fork failed);

return(1);

}

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

pid1 = getpid();

printf(child: pid = %d,pid); /* A */

printf(child: pid1 = %d,pid1); /* B */

value += 100;

printf(child: value = %d,value); /* C */

}

else { /* parent process */

wait(NULL);

pid1= getpid();

printf(parent: pid = %d,pid); /* D */

printf(parent: pid1 = %d,pid1); /* E */

value += 300;

printf(parent: value = %d,value); /* F */

}

return(0);

}
