delete pointers, but not the pointed object
I have a linked list, and in one of the functions I create a new object that points to one of the objects one the list.
Node* newPointer=new Node;
newPointer=myList->getHead()->getNext();
Is it possible to delete THE POINTER, and the pointer only – not the pointed object. If I write
delete newPointer;
then the object itself is deleted. I don’t want to do that!
If it don’t delete the newPointer will this lead to memory leakage?
Hope anyone can help me

Cant you create another pointer and reassign the object to that?
you seem a little mixed up concerning the scope of your variables....
Node* newPointer=new Node;
letsexamine this in more detail....
new Node
this part of the expression returns a pointer to a dynamically allocated chunk of memory. This is the chunk of memory that will need to be freed with delete.
Node* newpointer=
this part of the expression declares a local pointer variable on the stack. As it is local this pointer will automatically be destroyed when it leaves scope. Do not lose this pointer before you have had a chance to delete the newed memory or you will have a memory leak.
hope that helps.
Free the weed!! Class B to class C is not good enough!!
