Hello,

I have a function that generates some values (e.g. vertices in 2d space)
the number of which I dont know. So, it could generate 20 vertices, 100
vertices, or even 1 vertex.

void generateVals()
{
....
   //generate some values
...
}

What I want to do is store these values as they are generated.

I thought of using something like int *data = int[num_of_vertices] but I
will not know the num_of_vertices until after the generateVals()
function has finished, and when the function has finished I wont be able
to get/store the values any more.

I thought of using a dynamic linked list (such as the STL vector) and
after the generateVals function has finished to copy the values back to
the dynamic array *data (I need this in order to pass the values into
another function that uses int * arrays as input).

Anyways, my question is. Is there a more elegant way to do this by using
a dynamic array? or a linked list is the only way?

Thank you
Vasileios

P.S.
Some people might say that this posting is a bit of topic and should be
sent to a programming newsgroup, but I am looking for an answer specific
to c++ , so if you please know something do tell me.
