Okay, here''s a tricky question (well, probably not...) I am trying to use an array of pointers, NOT a pointer to an array. Normally this would be defined as such:

class thing{blahblahblah};

thing * array[500];
 

How do I define this dynamically? I don''t know how many there will be. Also I am reluctant to use a linked list because the number won''t change at all and so therefore I don''t need much manipulation - only at loadtime. I''m sure there must be a way of doing this using new or something... wise_guy

Try this:

typedef thing* thingPointer;
thingPointer * stuff = new thingPointer[500];

I can''t guarantee this''ll work because i''m away from my compiler but maybe try:

Thing* array[] = new Thing*[size];

I use something like this in my game-to-be...

    thing **my_pointers;my_pointers = new thing *[num_objects];for(int i=0;i<num_objects;i++)my_pointers<i> = new thing;    

//Ksero

I know, I know. I'm weak!!!

    #include<vector>class thing {/*...*/};typedef std::vector<thing*> vthing;int main(){  vthing thing_array;  while(!done) // or you run out of resources I suppose...  {    thing_array.push_back(new thing);  }}

Yeah, I''d use the vector of pointers as well, because I''m a slack bitch.

Maybe use the resize method once rather than push_back for each object pointer, but the main point is avoiding as much work as you can, right?

if the value won''t change then what are you talking about "dynamically"?

int Elements;

//do calculations on Elements
//get the final data for Elements

thing * pThing[Elements] = new Thing;

If you are using C++, why not use the STL template list ?
You can chuck anything in there. You can even have lists of lists. Imagine just being able to add in a node as you need it, at run time or real time.
