有关于计算机C语言的Pointer问题

Pointer types: give the correct declaration of t (that is, what is the type of t?). Eg: int k;t = &k;1. int *arr[5];t = arr[1];2. struct vnode *v;t = &v;3. vaddr_t entrypoint;t = &entrypoint;4. int main(int argc, char **argv) { t = main;5. struct thread ** thr;t = *thr;6. struct thread { ... char *t_name;const void *t_sleepaddr;char *t_stack;... } struct thread *thr = ... ;t = thr->t_name;希望能给点解释。谢谢 收起
