Can someone explain to me with this code at the switch statement? Anything improvement in my linked list deletion code?

Question

void delete_report()
{
printf("\n ___ Deleting a Fault Report ___ \n\n");
printf("Enter the Fault ID to delete: ");
scanf("%d", &element);
if (list == NULL)
printf("List is empty\n");
else if (element == list->faultid)
list = list->next;
else
{
temp = list;
while (temp->faultid != element && temp->next!= NULL)
{
prev = temp;
temp = temp->next;
}
if (temp->next != NULL)
{
prev->next = prev->next->next;
free(temp);
}
printf("Fault ID not found");
return;
}
printf("Fault Report %d has been deleted \n", element);
}

Answer 1

Your delete code fails, if you attempt to delete the last element as temp->next will be null. Change if (temp->next != NULL) to if (temp->faultid == element).
prev->next = prev->next->next; can be simplified to prev->next = temp->next;
You always print failure message and return. It should be on else.

Please put the code in the playgound. Copy the link and paste it here. I see no switch statement so likely your code got truncated.
