[Dev-C++] Iterator for stack and queue

[John H. <jhi...@ya...>]

I read in a book: "...You could use the STL stack class, which has an iterator...".
 
When I coded the following, I got a compiling error: undefined symbol "iterator"
    #include <stack>
    stack<int> numbers;
    stack<int>::iterator cursor;
I was trying to use iterator to display the content of a stack. 
 
Can anyone help me?
