Problem B. The program shown below uses the Pthreads API. What is the output from the program at LINE C and LINE P? Why? #include #include int value = 0; void *runner(void *param); /* the thread* int main int arge, char *argv) pid t pid; pthread t tid; pthread_attr_t attr pid fork0: if (pid 0) { /* child process */ pthread_attr_init &attr); pthread create(&tid, &attr, runner, NULL); pthread_join(tid, NULL printf("CHILD: value-%d", value); /* LINE C */ else if (pid>0)parent process*/ wait(NULL) printf("PARENT: value-%d", value); /* LINE P */ void runner(void *param) value 27 pthread_exit(O)
