Returning something to the calling routine

[CJPowell27]

Hey guys I'm supposed to implement a peek function where I return the

top nodes information to the calling routing through the argument list.  I 

have to do this because I can't display to user in a member function.

my structure  is 

struct node
{
	char * name;
  	char * location;
  	char * l_name;
  	char * address;
  	int miles;
  	int price;
  	int rating;
  	node * next;
};

my peek prototype looks list list::Peek(data & found_top);

So there will be many nodes returned? What is data type? Can you change it to array (reference to pointer so you can change pointer value) so you could return array?

There will be one node(the top one in the queue) being returned. What do you mean what data type is it? I can't change it to an array unfortunately, it's one of the requirements

I'm asking about "data" type. list list::Peek(data & found_top); Is it class/structure that has ability to store a pointer to node?

It is going to be a class but I'm going to the CS help department tomorrow to see the best way to organize the structures and classes tomorrow so I don't have a name for the class yet.

Ok, so you want to pass the top node you will find through argument found_top, but since you don't know how type of this argument looks like right now then all you need to know is that there has to be node pointer or long int, but node pointer would be more obvious.
