C program of bubble sort using linked list : In my previous code of Bubble sort algorithm, we have seen how to write a using for loop. Today we will learn how to write .

Bubble sort algorithm is a simple sorting algorithm that works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order. The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted.

Let us see how to implement bubble sort algorithm using linked list in . In my below code i have taken number of elements and elements to be sorted as input from the user and then displayed the sorted list of elements obtained by Bubble sort using Linked list.

C program of bubble sort using linked list :

```#include <stdio.h>
#include <stdlib.h>
#include <conio.h>

struct lnode {
int data;
struct lnode *next;

/* add a new entry to the linked list */
void llist_add(struct lnode **q, int num);
/* preform a bubble sort on the linked list */
void llist_bubble_sort(void);
/* print the entire linked list */
void llist_print(void);

int main(void) {
/* linked list */
struct lnode *newnode = NULL;
int i = 0,num,a[20]; /* a general counter */
printf("----------------------------------------------------------------------\n");
printf("-------------------made by C code champ ------------------------------\n");
printf("----------------------------------------------------------------------\n");
printf("\n\n\t BUBBLE SORT ALGORITHM USING LINKED LIST\n");
printf("\nEnter the number of elements : ");
scanf("%d",&num);
/* load some random values into the linked list */
printf("\nEnter the elements to be sorted : \n");
for(i = 0; i < num; i++) {
scanf("%d",&a[i]);
}

printf("\nList of input elements :\n");
llist_print();
printf("\n\nSorted List of elements by bubble sort :\n");
llist_bubble_sort();
llist_print();
getch();
return 0;
}

/* adds a node at the end of a linked list */
void llist_add(struct lnode **q, int num) {
struct lnode *tmp;

tmp = *q;

/* if the list is empty, create first node */
if(*q == NULL) {
*q = malloc(sizeof(struct lnode));
tmp = *q;
} else {
/* go to last node */
while(tmp->next != NULL)
tmp = tmp->next;

/* add node at the end */
tmp->next = malloc(sizeof(struct lnode));
tmp = tmp->next;
}

/* assign data to the last node */
tmp->data = num;
tmp->next = NULL;
}

/* print the entire linked list */
void llist_print(void) {

while(visit != NULL) {
printf("%d\t", visit->data);
visit = visit->next;
}
printf("\n");
}

/* preform a bubble sort on the linked list */
void llist_bubble_sort(void) {
struct lnode *a = NULL;
struct lnode *b = NULL;
struct lnode *c = NULL;
struct lnode *e = NULL;
struct lnode *tmp = NULL;

/*
// the `c' node precedes the `a' and `e' node
// pointing up the node to which the comparisons
// are being made.
*/
while(e != head->next) {
c = a = head;
b = a->next;
while(a != e) {
if(a->data > b->data) {
if(a == head) {
tmp = b -> next;
b->next = a;
a->next = tmp;
c = b;
} else {
tmp = b->next;
b->next = a;
a->next = tmp;
c->next = b;
c = b;
}
} else {
c = a;
a = a->next;
}
b = a->next;
if(b == e)
e = a;
}
}
}```

We hope that you all have enjoyed the above . If you have any issues with the C code or logic used in the program, feel free to contact us in form of comments.

1. Great article! We are linking to this particularly great
article on our site. Keep up the great writing.

2. I pay a quick visit day-to-day some websites and sites to read posts, except this web site
gives feature based writing.

3. My brother suggested I might like this blog. He was entirely right.
This post actually made my day. You can not imagine simply how much time I had spent
for this information! Thanks!

4. Have you ever considered about including a little bit more than just your articles?

I mean, what you say is fundamental and all. Nevertheless imagine if you added
some great graphics or video clips to give your posts more, “pop”!
Your content is excellent but with pics and videos, this website could definitely be one of the very best in its niche.
Superb blog!

5. This code is very helpfull and intelectual.I would have never been thought so deeply to crack the bubble sort for linked list.

6. Excellent website you have here but I was wanting
to know if you knew of any forums that cover the same topics discussed in this
article? I’d really love to be a part of community where I
can get advice from other knowledgeable people that share the same interest.
If you have any recommendations, please let me know. Cheers!

7. Definitely imagine that which you stated. Your favorite reason seemed to be on the internet the simplest factor to bear in mind of.
I say to you, I certainly get irked at the same time as people consider issues that
they just don’t realize about. You managed to hit the nail upon
the highest as smartly as defined out the whole thing with no need side-effects , other folks
can take a signal. Will likely be again to get more. Thanks

8. Hence, it is one of the pills recommended by many consumers annd
pharmacists. One of tthe easiest ways too prevent a false result is
by alerting yoyr physician to any medications you may be taking, prescription or over the counter, and usage of herbal
remedies. Irvingia Gabonensis: Irvingia gabonensis or African mango or bush mango is native to the West Africa and Southeast Asia.

9. The ever increasing value of this precious metal makes this an asset
that would help you achieve the suitable money during emergencies.
So how do you know which company has the best jewelry.
Better yet, take your daughter along and ask her advice.
