I posted a working example of a 3d array and a 3d vector there, and there are also some great comments in other posts.
Erm his not trying to make any kind of multidimensional array.
methinks i don't understand pointers

Okay, it's working!!! Actually, not really, the std::vector worked, it's just that I'm indexing past the extent of the vector. Thanks a whole lot everyone, consider yourself rated higher! :)

But if he understands that example, he will understand pointers MUCH better.

Use the iterators if you want to go through a vector
vector<type>::iterator start = vectorObject.begin();
vector<type>::iterator end = vectorObject.end();
while(start != end){
cout << *start << endl;
start++;
}
start is a pointer to the first object in the vector, and end is 1 past the last object stored in the vector
vector<type>::iterator start = vectorObject.begin();
vector<type>::iterator end = vectorObject.end();
while(start != end){
cout << *start << endl;
start++;
}
start is a pointer to the first object in the vector, and end is 1 past the last object stored in the vector

Okay, I tried using an std::vector, and it still doesn't work:for(int i = 0; i < num_objects; i++) { Object* object; Init_Object(&object); list.push_back(object);}list->DoSomething(); // crashes
Does Init_Object take an Object*, or an Object**?
If it takes an Object*, then Init_Object(&object) is wrong. &object, is the address of the pointer, not the address stored in the pointer.
Remember Object*, is a pointer. Object** is a pointer to a pointer.
