C++ :: Applying Bubble Sort On Linked List

Feb 27, 2015

I'm trying to apply a bubble sort on a linked list. It works in the first traversal, but then after the code cPtr = nPtr;, it inputs repeated digits at the end of the (semi-sorted) linked lists.

C :: Simple Program To Bubble Sort Values Of A Linked List

Nov 30, 2013

HelI have been tasked with creating a program which (1) takes in integer values from a user (until the user enters -1) and inputs these values into a linked list. This (2)original list is then to be printed out. The program then uses the algorithm "bubble sort" to (3)order the list in descending order before finally printing it out again.

I have managed to do this but I kind of cheated since I do not quite understand how to manipulate a linked list. What did was I took the values in the linked list and transferred them into an array and then did bubble sort on that array.how to do bubble sort on a linked list as well as how to print a linked list.

Code:

#include<stdio.h>#include<stdlib.h>
typedef struct node
{
int info;
struct node *link;

}Node, *NodePointer;
void printList (NodePointer head)
}

[code]...

C++ :: Import A File Containing Words And Numbers To Linked List - Bubble Sorting

I have a code able to import a file containing words and numbers to a linked list, but I also need to sort this linked list alphabetically. I've done research on this involving bubble sorting, but no explanationcan achieve this objective.

C++ :: Quick Sort Using Linked List?

Feb 23, 2013

I've been trying to implement a quick sort algorithm for linked list but when i try to run it with 1000000 values my compiler tells me its running too long and ends up not finishing. However when i run it with 10 values it seems to work fine.

Is there anyway to improve this run time?

Code: struct listnode *quicksort( struct listnode *data ) {
size_t length = 0;
struct listnode *pivNode, *temp = NULL, *low = NULL, *high = NULL, *ltail = NULL, *htail = NULL, *prev = NULL, *end = NULL, *next;
// Get length
for( struct listnode *cursor = data; cursor != NULL; cursor = cursor->next ) {
length++;
}

C++ :: Sort Function For Linked List Program?

Oct 7, 2013

I'm having trouble getting my sort function to work,

void Linkedlist::sort(int num)
{
node *q;
node *a;
int input=num;

[Code].....

I get a crash and I've narrowed it down to the last if statement. Also this function is meant to handle new members after 1 member has been added.

C++ :: Custom Linked List Sort Method

Apr 3, 2013

I am making a custom linked list (for fun!) and want to implement a sort method that sorts the stored data using the stored types > and < operators (will require the type to have these operators overloaded)

What is the best way to do this? I guess the first thing one might jump to would be to compare the current node with the the node to its "right" see if one is greater than the other. Then keep iterating through the list until you don't swap any more nodes. However I am thinking there is probably a more efficient way to do this. Here is my code so far:

#ifndef LIST_HPP
#define LIST_HPP
#include <string>

[Code].....

Surely there is a way to sort with only one iteration through the list?

is this correct? I used this sorting with numbers i don't know if it is the same with strings. When I run it, there are no errors detected, but when i try to view it, the inputs does not appear.

C/C++ :: Bubble Sort And Selection Sort?

Feb 19, 2014

You will write a program that uses a multidimensional array having 3 rows and 8 columns and sorts each of the rows using both a bubble sort and a selection sort.

You must declare the array inside of main. You will have a for loop containing the calls to bubbleSort and selectionSort. You need to pass into function bubbleSort and selectionSort the following: 1) each column of the multidimensional array, 2) the size of the column, and 3) a particular row number of the multidimensional array to be used for printing out the "pass" shown on the following pages.

I keep getting an error that the identifier for bubbleSort and selectionSort is not found. (Error C3861) Also, I feel like I'm missing something in int main() to get it to sort properly.

# include <iostream>
using namespace std;
int main()
{

C++ :: Bubble Sort - Put In Descending Order

Jan 22, 2014

so my program reads a file type which looks like this...

Michelle 71
Marcie 99
David 42
Rebecca 83
Jonathan 79
Matthew 77
Rose 7
Melanie 75
Kimberly 73
Roger 74
Scott 76
Bradley 77
Drextell 10
Heidi 70
Alan 68
Pearl 13
Jeanne 43
Heber 55

Here is whats in the header of the class

class StudentStat {
private:
int Size;

[Code].....

So as of right now the names are stored in a Names string array and the scores are saved in a Score int array. So my question is where do I begin with my bubble sort? I need it to put the scores in descending order so from greatest score to lowest but I need the Names in the string array to still be connected to the number from the list. Never done a bubble sort before so not sure where to begin.

C++ :: Program To Implement Bubble Sort

Feb 15, 2015

Design a C++ Program to implement the following functions:

a.)the function for bubble sorting : int bubblesort(int*a,int size).
b.)the function for merge sorting : int mergesort(int*a,int size).
c.)the function for generating array of random elements: int generate(int*a,int size) which calls the function rand() in c++.
d.)Test both bubble sorting and merge sorting with 10,100,1000,10000,100000 and 1000000,4000000 integers.

The integers are from the array generated by part c).calculate the time spent in calling each sorting.you may use a function in <time.h>to get the current time. Draw curves to compare the speed performance between the two functions. The merge sorting algorithm implementation must use recursion. you are expected to define a global array for holding result from merging two arrays.otherwise,it may cause a lot extra money in recursion.

Hint 1:use the following format to calculate the time cost for bubble sort.

{……..
Time1=Get the current time(call a function in <time.h>);
Bbblesort(….)
Tme2=Get the current time(call a function in <time.h>);
Time_cost=the difference between time 1 and tim2;
…….
}
Print your program and test results
