cross pointing between two classes

[yotama9]

Hi guys.

Is there a way to do the following:

class b{
     a * as;
}

class a{
     vector<b*> bs;
}

If not, and I have this:

class b{
}

class a{
     vector<a*> as;
}

how can I tell which a is pointing at a certain b?

Thanks

You can do the first one, if you declare class a

class a;

class b{
     a * as;
}

class a{
     vector<b*> bs;
}

thank.

I think I my meaning wasn't clear.

The segment of code I put up-there was meant to be placed in the header file as I want the reference to stay. The code I have placed is supposed to be in two different files.

I think I am clear now.

Anyhow, I have created a map:

map<b*, a*>

and I think it should work. Any ideas how to test this?

Thanks
