    Delete node in linked list..

    guys, how do i delete a node in linked list based on the user input value?

    is mine correct?
    Code:
    void deleteList(List *pList)
    {
    	int numDelete;
    	ListNode *pPre;
    	ListNode *pCur;
    
    	pPre=pList->head;
    	pCur=pList->head;
    
    	printf("Enter integer to be deleted : ");
    	scanf("%d", &numDelete);
    
    		while (pCur!=NULL)
    		{
    			if (pCur->entry==numDelete)
    			{
    				pPre->nextnode=pCur->nextnode;
    				free(pCur);
    			}
    			else
    				pCur=pCur->nextnode;
    		}
    }
    my header code is like follwing..
    Code:
    typedef int ListEntry;

    } ListNode;

    Have you tried it? What happens if numDelete is at the head of the list?
    If you understand what you're doing, you're not learning anything.

    I remember already commenting on the problems with the above code, in another thread, and you haven't learnt anything from it yet. I'm not going to repeat what I've already said.

    Starting extra threads for no good reason will just get others fed up with you. You wont get more help than if you had one thread, you'll get less. Good luck with that.
