Step 6: Searching for an item in the doubly linked list

Another important operation of the doubly linked list is searching for an item. To search for a specific item in the doubly linked list is a sequential process. The comparison starts from the beginning of the list until the target item is found or until the end of the list is reached. Therefore, the firs matched item is returned.

//Searching for an item in the doubly linked list

template <class Type>
ListElem<Type>  *LinkedList<Type>::find(int val){
          ListElem<Type> *tr;    
                             if(tr->data==val) break; //found the tartget=>stop searching
                             else tr=tr->next;//otherwise continue searching
              return tr;
