Thread: Linked List of Linked lists Revisited.

Hi, I am still having problems with my linked list of linked lists problem I posted last month, here is the linking function I have devised:

Code:

void lnk_C_and_H(Holiday *pHoliday, Customer *pCustomer, int nHolidays, int nCustomers)
{
	pCustomer = pHead;
	for(int i = nCustomers; i>0; i--)
	{
		pHoliday = Head;
		for(int j = nHolidays; j>0; j--)
		{
			if(strcmp(pHoliday->Holiday_code,pCustomer->Holiday_code))
			{
				pHoliday->pCustomer_lst = new Customer;
				pHoliday->pCustomer_lst = pCustomer;
				add_Customer(pHoliday->pCustomer_lst);
				break;
			}
			pHoliday = pHoliday->next;
		}
		pCustomer = pCustomer->pNext;
	}
}

also here is the add_Customer() function:

Code:

void add_Customer(Customer *pCustomer)
{
	if(pHead == NULL) 
	{
		pHead = pCustomer;
		pCustomer->pPrev = pHead;
		pCustomer->pNext = pHead;
	}
	else 
	{
		pCustomer->pPrev = pHead->pPrev;
		pHead->pPrev->pNext = pCustomer;
		pCustomer->pNext = pHead;
		pHead->pPrev = pCustomer;
	}
}

and here are the 2 structures:

Code:

struct Customer 
{
	string fName;
	string lName;
	char Holiday_code[5];
	Customer *pNext;
	Customer *pPrev;
}*pHead, *pHead2, *pCustomer;

struct Holiday 
{
	char Holiday_code[5];
	string location;
	string destination;
	string place_of_stay;
	double price;
	Customer *pCustomer_lst;
	Holiday *next;
	Holiday *prev;
}*Head, *pHoliday;

What I did was first create a linked list of customers and holidays, and then i tried to link them and (create I beleive) a third linked list of customers ona specific holiday, well it didnt work at all, I am completely perplexed by this problem and am not even sure if my methods are correct as I dont think I am suppose to make a 3rd linked list (am I?).

Any help on this matter would be greatly apreciated.
