找出链表的插入功能参数？

Question

My teacher gave the class for a driver to complete a program, and I'm unsure how to code the insert function because of it.

The line giving me trouble:

you.Insert(me,0);

you is for the default constructor and me is for an explicit value constructor, so this line is supposed create a node in you with the contents of me .

I'm lost understanding how to write the parameter to access me for my insert function

void WRD::Insert( ?, int new_data)

I'll include the explicit constructor I have, any insight understanding this mentally will help. (included example of what insert should look like or do based on an example I was given.)

WRD::WRD(const string & s)
{
    cout<<"one called\n";
    front = 0;
    for(unsigned i=0; i<s.length(); i++)
    {
        AddChar(s[i]);
    }
}


class node
{
public:
    char symbol;  
    node *   next; 
};

v

oid Insert(node * &ptr, int new_data)
{
    node *new_ptr = new node;

    new_ptr -> data = new_data;
    new_ptr -> next = 0;  //always initialize a pointer

    if (Empty(ptr))
    {
        ptr = new_ptr;
    }
    else if (new_ptr->data <= ptr->data)
    {
        new_ptr->next = ptr;
        ptr = new_ptr;
    }
    else
    {
        node *fwd_ptr=ptr, *pre_ptr=ptr;

        while(fwd_ptr!=0 && (fwd_ptr->data < new_ptr->data))
        {
            pre_ptr = fwd_ptr;
            fwd_ptr = fwd_ptr->next;
        }

        if (fwd_ptr == 0)
        {
            pre_ptr->next = new_ptr;
        }
        else
        {
            new_ptr->next = fwd_ptr;
            pre_ptr->next = new_ptr;
        }
    }
}

Like this I think (assuming I've understood you right)

void WRD::Insert(const WRD& w, int new_data)

It might help to show more of your driver program, in particular how you and me are declared.
