C :: Delete A Node From Singly Linked List
Oct 18, 2014I was trying to write a function in C to delete a node(only from the middle) from a Singly Linked List. I wrote one but not sure if the code will work fine under all test conditions. I have tested it and shows no error so far.
Code:
void deleteAt(struct node *root, int number){
while(root->link != NULL) {
if(root->link->item == number) //checks if the next node is the element to be deleted {
root->link = root->link->link; //points the link of the element to be deleted to the element before the element to be deleted
}
else
root = root->link;
} }
Or is there a better way to do this?

C :: Singly Linked List
Mar 7, 2013I am having difficulty getting my program to run. I have looked and looked many times trying to figure out what I am doing wrong. I have a hunch that it's my load function that's acting up, but from my perspective, my creation of my singly linked list looks good. From the creation of my singly linked list, does anything stand out as being abnormal?

C++ :: Singly And Doubly Linked List - Order Inserted Elements According To Certain Pattern
Sep 13, 2014I need to make singly and doubly linked list classes that can insert elements. Once the lists are created, I need to order the linked list elements according to a certain pattern.
order2 pattern:
input: 0 1 2 3 4 5 6 7
output: 1 0 3 2 5 4 7 6
order3 pattern:
input: 0 1 2 3 4 5 6 7 8 9 10 11
output: 2 1 0 5 4 3 8 7 6 11 10 9
sequence order pattern:
input: 0 1 2 3 4 5 6 7 8 9 10 11 12 13
output: 1 0 4 3 2 8 7 6 5 13 12 11 10 9
reverse pattern:
input: 0 1 2 3 4 5 6 7 8 9
output: 9 8 7 6 5 4 3 2 1 0
My instructor has given the description of the required classes in a file interfaces01.h as:
#pragma once
#include <cstdlib>
struct ISingleNode {
ISingleNode() {}
virtual ~ISingleNode() {}
virtual void setValue(int value) = 0;
virtual int getValue() = 0;
[Code] ....
However when I am compiling these files in vs 2013 I am getting the error: cannot open include file Singlenode.h,Singlelist.h.
Also I am not too sure about the sorting and reverse logic. How can I implement these logics.

C/C++ :: Storing Nodes Into A Linked List?
Apr 18, 2015I'm simply trying to locate possible logic errors because if I could fill this list properly, I can finish my project very easily. This is just a small portion of a very immersive project.

I wish to clarify but can not find where to edit the OP. I believe the list is still empty because I attempt to do a simple read through the list by accessing the head and then reassigning the list to the tail of the list. However, the program never enters the while loop

C++ :: Rebinding Allocator For The Nodes Of Linked List?
Mar 27, 2014I am coding a singly-linked list container. Of course, internally it uses Node<T>.
Question: what is the correct way to use the allocator given by the user? I ask, because I've read this on the rival C++ Reference:
std::list<T, A> allocates nodes of some internal type Node<T>, using the allocator std::allocator_traits<A>::rebind_alloc<Node<T>>, which is implemented in terms of A::rebind<Node<T>>::other if A is an std::allocator
[URL]...
The above doesn't seem right to do, because then what should pointer and const_pointer be?
using pointer = std::allocator_traits<Alloc>::pointer;
using const_pointer = std::allocator_traits<Alloc>::const_pointer;
// but we're using Alloc<Node<T>> not Alloc<T>
// so maybe do this?
using pointer = value_type *;
using const_pointer = const value_type *;
C++ :: Deleting Linked List Nodes Recursively
Jun 25, 2014I am creating a Linear linked list in c++. I've written all the functions for it, but now I want to try and do them using recursion.
I managed to make functions for adding and displaying nodes on the list, but I am stuck on the function for removing nodes. First I want to try and write a function the removes the last item on the list. But for some reason my code isn't working properly.
Here is the code :
void removeLastItem(node * &head) {
if(!head) {
delete head;
head = NULL;
[Code] ....
NODE - My structure name
NEXT - The pointer to next element.
HEAD - The first (head) pointer.
The couts in the if statements are just for testing. In fact after I Run my program it does as it is supposed - enters the second if /b]case as many times as there are elements and then executes the first [b]if statement. But for some reason it does not delete the actual node.
C++ :: Swapping Nodes In Doubly Linked List?
Nov 15, 2014I've been working on this linked list priority queue . I know that the root of the problem is in my swapUp() function (swapping the positioning of two nodes based on their priority), because the list works great up until it is called. The seg fault is not actually being caused by swapUp(), it's being caused by peekAt(), which returns the element in the node at position n. But the error does not occur unless swapUp() is called first, so that is where the issue is (I think).
There is also a seg fault being caused in the destructor, which I believe may have the same root cause in swapUp().
PRIORITY QUEUE:
#ifndef JMF_PriorityQueue
#define JMF_PriorityQueue
#include <iostream>
#include <string>
template <typename T>
class PriorityQueue{
[Code] .....
Okay, so I've tried implementing SwapUp() in a different new way, but it's still giving me the same problem
template <typename T>
void PriorityQueue<T>::swapUp(Node * target){
Node * partner = target->next; //Partner = target next
[Code] .....
This is such an elementary logic problem I don't know why I'm having so much trouble with it.
C :: Quick Sorting Array Of Nodes In A Linked List?
Oct 19, 2013I'm trying to sort the elements in a linked list which contain a variable amount of data in any given case. In the sample code, the code is more static, but I plan on adding it to much more dynamic code once I have it figured out. My main problem is that I am not sure how to sort the linked list while still keeping the correct pointers to the nodes. I thought about writing my own custom quick sort instead of using the C-standard library function, but how I would keep the pointers to the next nodes correct eluded me. Here is my code so far :
Code:
#include <stdio.h>
#include <stdlib.h>

Nov 21, 2014I need to sort the Linked list from highest to lowest or in this case. The highest Bribe gets the higher priority on the list. I have looked all over the internet and have found some pretty decent examples but I still don't truly understand how to sort it. I think from looking at so many examples I have confused myself even more. I was reading about using Doubly Linked list but I don't even know if were allowed to use that.
1. The program runs perfectly at the moment. It prints out the list but does not sort it.
2. How to make sure that I am deleting the allocated memory correctly in the deconstructor.

I don't know how to do this if this was deleting by position would have been easier, but the user don't know and don't have to know the position of every book in the list it should delete the books by there title and i'm kinda lost of the delete function at line 47 and particularly at line 55 and 62, it kind difficult to traverse with the values or the data of the node for the position is simpler.
