C :: Singly Linked List
Mar 7, 2013
I 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;
}
[code]....

I want to make a singly linked list of structs with a custom datatype. Sadly, I dont think I understand either.
#include <iostream>
using namespace std;
struct datatype
[Code]....
Basically, I cant figure out how to insert a strcut with a string, random ID number, and a random salary amount, into a linked list.

Code:
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
struct node {
int data;
struct node *next;
[Code] ....
The above code is a SLL. I have a problem in my deleteNode function. I can't delete the exact data on the list. How to do this right?

I 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?

I don't know why my code is not working. It's from line 249 - 266
void SLL::deleteDuplicate(){
Node* temp = head;
Node* p = temp;

I 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.

I've written this class and struct to create a singly linked list. The data is stored in the binary file which I've opened and read. I'm trying to load said data into a class type array. The errors I'm getting are "incompatible types in assignment of 'StatehoodInfo' to char[3]" Lines 130-134 is what I was working on.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <sstream>
#include <string>
#include <cstring> //For char[] string functions

I've written code for a selection sort algorithm to sort through a singly linked list, However, it only brings the smallest node to the front, but doesnt swap positions of any of the remaining nodes, even though they are not in order.
Input list: 3 6 17 15 13 15 6 12 9 1 2 7 10 19 3 6 0 6 12 16
Sorted list: 0 6 17 15 13 15 6 12 9 1 2 7 10 19 3 6 3 6 12 16
Code:
#include<stdio.h>
#include<stdlib.h>
struct node{
int val;
struct node *next;

I'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
{
Node <T> *hunter1 = Head;

I 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..

Code:
// 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?

I'm working on a linked list and was wondering how this looks to everybody else for a deleteList function.

I 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

I 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?

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

I 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."

I 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?

I 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.

My 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.
#include<iostream>
#include<string>
using namespace std;
class Node {
public:
int value;
Node * next;

When 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???

I had ...
class List;
List *deletezeroendlist(List* L);
class List {
public:
intdigit;
List*nextDigit;
public:
List():digit(0), nextDigit(NULL){}
List(int d, List *next):digit(d), nextDigit(next){}
I have tried many different ways but it is still not the answer / perform the function List *deletezeroendlist(List* L)
EX
L=12345600 -> L=123456
or L=01203000 -> L=01203
remove the 0 at the end
