Remove duplicates in Linked List

I dont know whats wrong with my code. Also, how would you delete a node in the linked list.

for( IntNode* i = head; i != 0; i = i->next ) {

        IntNode* prev = i;
        for( IntNode* j = i->next; j != 0; j = j->next ) {

            if( j->data == i->data ) {

                IntNode* temp = j;
                prev->next = j->next;
                delete temp;
            }
            prev = prev->next;
        }
    }
