mis.c:24: error: request for member ‘vertex’ in something not a structure or union


ammm....the problem? thanks....

Code:

typedef struct node{
	int vertex;
	struct node *next;
}ListNode;

ListNode *search_and_insert(ListNode *front, int v){
	ListNode *temp;
	ListNode *final;
	temp=front;

		while(temp!=NULL){
		if(temp->vertex==v){
			return NULL;
		}
			temp=temp->next;
			if(temp->next == NULL){
				final = temp;
			}
		}
		
		final.vertex = v;
		front = final;
return front;
}

final isn't a struct, it's a pointer, so you need to use the -> accessor.

thanks
