C++ linked list

Please I Need help in retrieving the value of the node of its given position

here's my code, but there's is a problem in returning the value . .

Code:

int n=1;
      Node *newNode=head;
      while(newNode->next!=NULL)
       {
            if(newNode->data==location) {
               newNode=newNode->next;
                n++;
            } else {
                break;
           }
       }
      return newNode->data;

if i have 7 2 3

I enter position 1 and it must return 7....

but i have a new element at first so 2 7 2 3

I enter position 1 why is it returning the same value "7". .. instead of 2 . . that's my problem

It would be better to start completely over.

You're ok until we get to here:
if(newNode->data==location)
Will compare the data in the node to the location you want to find. These two things don't really coincide. Plus, you break the loop at the point the comparison is false, which will be most of the time.

You should be counting the number of nodes you've passed over, and break when you reach the location. Data has nothing to do with it.

I'm new also but i think this is about what you are trying to do

Code:

int location;   // which list do you want to access?
int ctr;         // needs a counter to keep track of the list we are currently in
node* conductor = head;   // start at the beginning
for(ctr = 1; ctr != location; ctr++) //run this loop until you are at the nth list
{
    if(conductor->next == (node*)NULL) // seeing if there is a next list
    {
        // location does not exist, insert some error handling stuff
        break;
    }
    conductor = conductor->next; // moving thru the next link
}
if((ctr == location) && (conductor != (node*)NULL))  // pointer is good, and we should be in the right list
{
return conductor->data;   // return some data
}

The term "list" is used inappropriately here. The term you seek is "node."
There is only one list, and it links several nodes together.

you're new, so the forum rules should be fresh in your memory, having read them very recently, right? so why did you post a complete solution, which is against the rules?

Sorry, I didn't know that

So the *head is the list, *conductor is a node, and conductor->next is a link? Is there a special name for a list that loops, where the last link points to the first node? I will read the forum rules when I get home, wasn't trying to agitate anyone. List's are kind of a weird concept, at least they seemed that way when I first read about them because of how they are accessed. It didn't make any sense to me until I really focused on a few functions In my book about them.

Circular linked list.
