Linked list search??

**ren** · 04-10-2002

I have accepted input into variable head->array[a]. I now have to search the linked list to see if the input in array[a] is already stored. I have been trying to convert a linked list search from C++ but have not been successful can anyone please help me?

This is what I have:

head->array[a]==target;
previous=NULL;
current=head;

while (current !=NULL && (*current) !=target)
{
previous=current;
current=*current->next;
}

if ((current !=NULL) && ((*current) == target))
printf("your data has already been entered");

head->array[a]==target;

I guess that was ur problem...

say...

head->array[a]=target;

if ((current !=NULL) && ((*current) == target))
printf("your data has already been entered");

if(*current ==target)
printf("your data has already been entered");
else
--------- /* data not entered. do what ever u want to. */

Regards.

Code:

struct node *search ( struct node *list, Item key, int searchIndex )
{
  while ( list != NULL && list->array[searchIndex] != key )
    list = list->next;
  return list;
}
