C :: Dynamic Array Of Linked List
Jan 29, 2014I am trying to create an dynamic array (lno) This array will store addressess of different Linked list. What exactly I want is:- Take N Number of Linked List user want to create> eg. 2 now It will create 2 linked list for which I am trying to allocate memory.
Code:
struct node{
int data;
struct node *next;
}
first;
lno[0] Node 0's first address stored in ln[0] lno[1] Node 1's first address stored in ln[1] Here is the code in which I am facing problem with error Illegal structure Operation
Code:
#include<conio.h>#include<stdio.h>
#include<stdlib.h>
struct node
{
int data;
struct node *next;
};

C++ :: Dynamic Data Structures (Linked List)
Oct 26, 2013I need an explanation of what linked lists are. How the nodes are been defined and used, especially in an object oriented programming. With a code example.

Apr 29, 2013I'm trying to write a function that takes two linked lists and creates a third one with only the common elements.
It assumes the first list (the caller) has no dups, but it doesn't seem to be working. The program doesn't crash, it just hangs when it is supposed to display L3 (the third list)..everything else runs and is displayed fine.
template <typename T>
LList <T> LList <T>:: common (LList <T> &B)//common fct

C :: Dynamic Linked Lists
Oct 14, 2013In our homework assignment it states to, "write a set of dynamic linked lists" and so on. Now, the problem I'm confusing myself is at the storage inside of each node. To my understanding, each node contains the prev and next nodes, but also a pointer to the data, in this case being a string. He has asked us to manage these strings as rows of chars such as
char[0] = c // first node being addressed here
char[1] = a
char[2] = t
char[3] =
char[4] = d // second node starting here
char[5] = o
char[6] = g
char[7] =
I have written my code where each node is holding a string, not separated as shown above... my question is to how you can build your doubly linked list where each node is being address a set of chars.
C :: Insert Linked List Into Another Linked List
Jun 29, 2013I have a linked list comprised of chars like so...
Code:
node1 - "p"
node2 - "o"
node3 - "p"
I need a function that will take in three perameters...node *replaceChar(node *head, char key, char *str)Stipulations of this function. head is the head of the list, 'key' and 'str' are guaranteed to contain alphanumeric characters only (A-Z, a-z, and 0-9). str can range from 1 to 1023 characters (inclusively). So if I call this function with these perameters..
Code:
node *head == /*the head of the list to be examined*/
char key == "p"char *str == "dog"The new list will look like this...
node1 - 'd'
node2 - 'o'
node3 - 'g'
node4 - 'o'
node5 - 'd'
node6 - 'o'
node7 - 'g'
All instances of 'p' were replaced with 'dog' I have a toString function which takes in a string and converts it to a linked list and returns the head. So assume that you can call the function on str = "dog" so...
Code:
toString(str) == /*this will return the head to the list made from the str*/
If it's unclear what my question is...I am stumped on how to write the replaceChar function the one that takes in three perameters..
C :: Linked List / Adding Element To Beginning Of List
Dec 31, 2014Code:
// Write a function called insertEntry() to insert a new entry into a linked list.
Have the procedure take as arguments a pointer to the list entry to be inserted (of type struct entry as defined in this chapter), and a pointer to an element in the list after which the new entry is to be inserted.
// The function dveloped in exercise 2 only inserts an element after an existing element in the list, thereby prenting you from inserting a new entry at the front of the list.
(Hint: Think about setting up a special structure to point to the beginning of the list.)
#include <stdio.h
struct entry1 {
int value;
struct entry1 *next;
};
[code]...
This is a working version of the exercise, but I don't think I'm doing what's asked. I was able to add an element to the beginning of the list using an if statement, not creating a special structure that points to the beginning of the list. How would I go about creating a special structure that points to the beginning of the list to add a new element at the beginning of the list?
C :: War Card Game With Linked Lists And Dynamic Memory
Apr 23, 2013I am struggling to finish up my game of War. There are a few problems I have ran in to. My shuffle function seems to work fine. I believe my problem lies within my game rules. When I run my code, the game usually plays all the way through but almost always ends in 'War'. I am struggling to get the game to restart after running once. I am not sure how to clear the list and start over.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <time.h>
#include <Windows.h>

C# :: How To Order A Dynamic List
Nov 11, 2014I have to following:
List<string> keyList = new List<string>();
keyList = data.First().Keys.ToList();
I also have a table with a column called display_order which i need to use in the order by
I have tried:
keyList = data.OrderBy(s => s.).ToList();
keyList = data.First().OrderBy(keyList).ToList();
orderBy = "Display_Order asc";
keyList = data.First().OrderBy(orderBy).ToList();
keyList = data.First().OrderBy().ToList();
keyList = data.First().OrderBy(keyList.display_order).ToList();
Am I missing something?
C++ :: Linked List Delete List?

C :: Doubly Linked List
May 15, 2013I need to make the functions using these function prototypes. I am mainly having problems with GetFirst() and SwapData() but how to do it..
Header File with Prototypes
Code:
#ifndef LINKEDLIST_H
#define LINKEDLIST_H
/**
* @file
* This file provided a doubly-linked list implementation capable of storing any arbitrary data.
* The list implementation relies on a chain metaphor: a list is merely a sequence of links
* (ListItems) and there is no separate construct to represent the entire list, each ListItem in it

C :: Linked List Search
May 7, 2013I read an article on linked list here: C Linked List Data Structure Explained with an Example C Program
Code:
struct test_struct* search_in_list(int val, struct test_struct **prev)
{
struct test_struct *ptr = head;
struct test_struct *tmp = NULL;
bool found = false;
}
[code].....
What is "if(prev)"? Wouldn't "prev" always have the same value? Secondly, if tmp is NULL (which will be the case when the loop if(ptr->val == val) finds a match the first time it is run), is *prev assigned a NULL?
C :: Double Linked List
Jan 2, 2014I'm having a small issue here with my linked list.I built a linked list with strings and it worked perfectly.Now since i'm using strtok() to separate the string.for now here's what i've got:
Code:

#include <stdlib.h>
#include <string.h>
typedef struct dict_word *word;
typedef struct node *Node;
typedef struct double_linked_list *DLL;

C :: Static Linked List
Jan 6, 2014I have the codes for the functions: "Given the functions that we have discussed and defined in the class and the code that we have created, create the code for the Delete Node function and the Search function. Create an application that will incorporate all the functions that we have discussed and the new ones that you need to create. The application should allow the linked list to be built initially from a text file. The application should then allow for the user select an operation to perform. The acceptable operations are
- to search for an item
- to delete an item
- to enter a new item
- to exit the application
After the initial build and loading of data from the textfile, the application should print a listing of each item in the list and the node that it is located in. after a delete or insert, the application should display an output of the list again showing each item in the list and the node that it resides in.
The data item for this problem will be the inventory structure that we created in class and the data is in the inventory file that you already have downloaded."
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?
Code:
typedef struct Node {
char word[LENGTH+1];
struct Node *Next;
} Node;

C :: Sorted Linked List
Apr 2, 2013I been ask to create a sorted linked list module, and to test each function with 1 unit, 2 +.so i wrote my addtofront function( we have to use the same as the teacher)
Code:
struct MyList{
char * name;
Sorted * AddmyChar;
struct MyList * next;
}
[code]....
but i cant seem to test it because it always display a seg fault.... i dont know what i did wrong....how do i call this function in main to display a string i want?
C++ :: Linked List Using Templates
May 27, 2014I decided to make a linked list program using classes and templates.I implemented my linked list and added some basic functions, everything worked just fine. Then I proceeded to add templates...First, the error list:
#pragma once
template<class T>
class Node {
private:
Node* next;
[code]....
To sum up: Something's wrong with the templates that I used in "List.cpp" and what it could be.
C++ :: Linked List Won't Take Big Numbers
Jan 2, 2013My program is almost done all that is left is entering big numbers, the program can add and subtract small numbers but not big numbers because it puts them all in one node, I need the program to store each number in a node.

C++ :: Traversing A Linked List
Mar 30, 2013When I am traversing a linked list ...i suppose we can do it only with pointers
like p is a head node pointer then
p
p->next
p->next->next
p-next->next->next
so on represents a link...
if i have to pass head node as struct variable itself...can i traverse a link using dot operator??
p and p.next and how to retrieve third and remaining links through this method if we can traverse like this???
