2. Assuming that the actual process ids of the parent and child process are 2600 and 2650 respectively, what will be printed out at lines A, B, C, D, E, and F? Be sure to explain your answers, specifically addressing sharing or non-sharing of variables between parent and child processes. int main() { pid_t x, y; int value = 90; value += 30; /* fork a child process */ x = fork(); if (x < 0) { /* error occurred */ fprintf(stderr,Fork failed); return(1); } else if (x == 0) { /* child process */ y = getpid(); printf(child: x = %d,x); /* A */ printf(child: y = %d,y); /* B */ value += 20; printf(child: value = %d , value); /* C */ exit(0); } else { /* parent process */

y= getpid(); printf(parent: x = %d,x); /* D */ printf(parent: y = %d,y); /* E */ wait(NULL); printf(parent: value = %d , value); /* F */ } }
