您似乎不知道什么是指针，因此，我真诚地怀疑任何在线论坛都对您有用.

请阅读有关C的好书.一旦您了解了基础知识，在线论坛将对您有很大的帮助.

You don''t seem to know what is a pointer, so I sincerely doubt any of the online forums are going to be useful to you.

Please read a good book on C. Once you understand the basics, online forums will be of great help to you.

classname object;
classname* pointer_object;
object.member_function();
pointer_object->member_function();
pointer_object[0].member_function();
pointer_object[10].member_function(); // if pointer_object is an array of classname
