Nested classes question...

hi guys...

i have a class called Astar and a Node class within it...i have a method readfile() outside the Astar class...I want to now declare a vector of Nodes within readfile() but I get an error: E2451: Undefined symbol Node...i write:

vector <Node *> VectorOfNodes

what's the problem?

Best Regards,

Here is the structure of the code:

I am giving the strcutre below...I've removed most of the things so it's easier to understand. The error is in the line: vector <Node *> CityNode; in the method: readfile()

class Astar
{
public:

class Node
{
public:

int x;
int y;

}

}AstarSearch;

Then:

void readFile()
{
vector <Node *> CityNode;
.................
.................
}

>vector <Node *> CityNode;
You need to tell the compiler that Node is nested in Astar:

Code:

---

vector <Astar::Node *> CityNode;

---

works!!! thanks a lot...was confused about this for 2 days...best forum ever!
