The ADT UnsortedType List function DeleteItem(ItemType item) creates an endless loop error when trying to delete a word or key that is not in the list.

Example: Delete the word letter from the unsorted list.

Here are the lists contents before the DeleteItem(ItemType item) call:

The question is how can I exit gracefully from the DeleteItem(itemType Item) call when the word or key is not in the unsorted list and not get an endless loop but instead printing out a message that the word letter is not in the loop? What code can be added?

void UnsortedType::DeleteItem(ItemType item)

{

NodeType* location;

NodeType* tempLocation;

location = listData;

if (item.ComparedTo(location->info) == EQUAL)

{

tempLocation = location;

listData = listData->next;

}

else

{

while (!((item.ComparedTo((location->next)->info) == EQUAL)))

location = location->next;

tempLocation = location->next;

location->next = (location->next)->next;

}

delete tempLocation;

length--;

}
