C++ :: Linked List BubbleSort - Number Of Elements
Apr 22, 2013Why isn't this bubble sort working?
void LList :: bubbleSort (LList A, int n){
Node *temp;
temp = Head;
int hold;
for (int pass = 1; pass <= n-1; pass++) // number of passes needed for bubblesort is the number of elements-1 {
for (int c = 0; c < n-pass; c++)//only runs for unsorted elements

It is passed the LList, and the number of items in the list...
C++ :: Creating A Linked List Of Common Elements From Two Other Linked Lists
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

Node <T> *hunter1 = Head;

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++ :: Returning The Number Of Elements In A List
Jul 24, 2014I am given an array with n elements but need to write a function where it returns n-1 elements. Do I need a loop for this? Or must I write a prototype...
Here is what I have thus far:
//given array with 5 elements function must return value 4 elements since -1 is a special character length of list is finite
#include <iostream>
using namespace std;
int main () {
int array [] = {1, 4, -1, 3, 2};
cout << "The array has " <<sizeof (array)/ sizeof (int)<< " elements"<< endl;

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/C++ :: Using Linked Lists To Swap Two Adjacent Elements
Jan 6, 2015I am reading a book currently on data structures in c++. The questions I have is how I would be able to swap two adjacent elements by adjusting only the links (not the data) using, a) singly linked lists, doubly linked lists.
For the single linked list which I am somewhat familiar with (by the content of the book), I would consider taking the Node A, and copying its data into a new Node temp, then re-routing the pointer from whatever connected to Node A, now to Node temp. now I want to re-route the pointer of Node B to Node temp and Node temp to whatever Node was being connected from Node B. Is this the correct approach?
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++ :: How To Restrict User To Enter Four Digit Number Only
Aug 22, 2014I am trying to write up something to have a user to enter a four digit number. Only four digits, Ex: 0001, 0116, or 9999. There is no getting around the selection 0001 or 0002. I understand if not done correctly, the first three 0's will be ignored.
I've been just playing around with what I have below but I just don't remember how to do it nor can I find a good example online to figure it out. I know it is not correct just typing to try to remember. I am aware that it is gibberish right now, this is just me brainstorming.
int number;
cout<<("Please enter the four digit number(Ex: 0001):
");
cin>> setw(2) >> number;
cout<<)"Please enter four digit date. Two digits for month and two digits for year:

C++ :: Program That Asks User To Enter Even Number Only
Mar 23, 2014Write a C++ program that asks the user to enter an even number only. If the user enters an odd number the program should use input validation to ask the user to enter another number.
- The user can enter as many numbers as he wants
- The program should also keep a count of how many numbers entered and display how many odd and even numbers entered.
