Here is source code of the C Program to remove duplicate elements from a linked list. A singly linked list is the most simple type of linked list, with each node containing some data as well as a pointer to the next node.That is a singly linked list allows traversal of data only in one way. Given a 'key', delete the first occurrence of this key in the linked list. If you're asking about how to delete any node from the linked list, you can delete any node by connecting the previous nodes next to the deleted nodes next, then using delete on the node that you are deleting.
