CPtrList- how to get index of a element

[sgrm123]

Hi,

How to get index of a element in the cPtrList



class CAge

{

public:

CAge(int nAge){m_nAge=nAge;}

int m_nAge;

};



typedef CTypedPtrList <CPtrList, CAge*> CAgePtrList;

CAgePtrList list;

POSITION pos;

CAge *p1 = new CAge(21);

CAge *p2 = new CAge(40);

list.AddTail(p1);
list.AddTail(p2);

POSITION pos1 = list.GetHeadPosition();
POSITION pos2 = list.Find(p2,NULL);
int nIndex=pos2-pos1;


if I subtract pos2 from pos1 I am getting the value 12. I expect the value 1 since it is 2nd element.
