hi, from this code as input
[source]
char get_op( )
{
    char result;

    do
    {
        cout << "Please enter an operator for the expression node: ";
        cin >> result;
        cout << result << " has been read." << endl;
    }while(strchr("+-*/", result) == NULL);

    return result;
}
[/source]
to this code as implementation:
[source]
template <class Item>
       void expression<Item>::insert_left(const char op, const Item& entry)
    {

        if(root_ptr == NULL)
        {
            root_ptr = new exp_tree_node<Item>(op);
            root_ptr->set_left(new exp_tree_node<Item>(entry) );
        }

    }
[/source]

when op is accessed and displayed it shows as ascii and not the intended operator(+-*/) any idea why this is happening??
