UNSORTED LINKED LIST

[hectorespresati]

Hey guys I'm trying to do this program but when I run it doesn't work...
Hopefully some of you will be able to see the error.

Phase I (30 points)

• Struct Node

• Class unsortedLinkedList (or shorter name) with a private HEAD pointer.

Include constructor method to make HEAD null.

• Main method that establishes the mylist object and calls the supporting

methods (insert, displayAll, …)

• Insert Method that places a new node at the beginning of the list

• DisplayAll method that displays each node’s info value on the screen

Phase II (40 points)

• Search method that received an int value as intput and returns true or false

back to main to indicate if the value was found or not.

• Delete method that deletes a node at any location within the linked list.

• Furthermore, the search and delete methods should not “bomb out” with an

empty list.
