Thanks Nibu.

CAnotherObject anObject;
CObject *pToAnObject = &anObject; //pointer to anObject
 
//In this case don't delete just set to NULL. This will break the link between
//pToAnObject and anObject.
pToAnObject = NULL;

CAnotherObject *anObject = new CAnotherObject;
CObject *pToAnObject = anObject; //pointer to anObject
 
//In this case you have to identify whose responsibility is it to <code>delete </code>the 
//object. Best would be to allow <code>anObject </code>to <code>delete </code>itself unless otherwise
//specified.
pToAnObject = NULL;
 
//delete anObject.
delete anObject;
