An event that occurs at some point in time when the system does not deliver a service as expected by its users is called . . . . . . . . A file owner does not have a permission to edit the file but the group to which the file owner belong do have the permission to edit it. Can owner edit the file? What is the output of this program? #include<stdio.h> #include<pthread.h> #include<semaphore.h> sem_t st; void *fun_t(void *arg); void *fun_t(void *arg) { pthread_exit("Bye"); } int main() { pthread_t pt; void *res_t; if(pthread_create(&pt,NULL,fun_t,NULL) == -1) perror("pthread_create"); if(sem_init(st,1,2) != 0) perror("sem_init"); if(pthread_join(pt,&res_t) == -1) perror("pthread_join"); if(sem_destroy(&st) != 0) perror("sem_destroy"); return 0; } How can you avoid overfitting ?
