    struct node

    {

    int data;

    struct node * next;

    }list;

    for deleting a node from list first we have read a element which u want to delete and then we have identify previous node of that element.

    scanf("%d",&x);

    void deletenode(struct node * list)

    {struct node * l1=list,temp;

    if (l1->data==x) l1=l1->next; //deleting first element

    else

    {

    while (l1->next->data!=x) and (l1!=NULL) l1=l1->next;

    temp=l1->next; //here l1 points to previous node

    l1->next=l1->next->next;

    delete (temp)

    }

    }



    void delete_last()
    {

    node *q;


    q=head;
    while(q->next->next!=NULL)
    q=q->next;
    q->next=NULL;
    }
