Bubble sort in C
Bubble sort in C to arrange numbers in ascending order, you can modify it for descending order and can also sort strings. The bubble sort algorithm isn't efficient as its average-case complexity is O(n2) and worst-case complexity is O(n2). There are many fast sorting algorithms like Quicksort, heap-sort, and others. Sorting simplifies problem-solving in computer programming.
Bubble sort program in C
/* Bubble sort code */
#include<stdio.h>
#include<conio.h>
void main()
{
int array[100], n, c, d, swap;
{
int array[100], n, c, d, swap;
printf("Enter number of elements\n");
scanf("%d", &n);
scanf("%d", &n);
printf("Enter %d integers\n", n);
for (c = 0; c < n; c++)
scanf("%d", &array[c]);
scanf("%d", &array[c]);
for (c = 0 ; c < n - 1; c++)
{
for (d = 0 ; d < n - c - 1; d++)
{
if (array[d] > array[d+1]) /* For decreasing order use < */
{
swap = array[d];
array[d] = array[d+1];
array[d+1] = swap;
}
}
}
{
for (d = 0 ; d < n - c - 1; d++)
{
if (array[d] > array[d+1]) /* For decreasing order use < */
{
swap = array[d];
array[d] = array[d+1];
array[d+1] = swap;
}
}
}
printf("Sorted list in ascending order:\n");
for (c = 0; c < n; c++)
printf("%d\n", array[c]);
printf("%d\n", array[c]);
getch();
}
}
Bubble sort program in C language using function
#include<stdio.h>
#include<conio.h>
void bubble_sort(long [], long);
void main()
{
long array[100], n, c;
{
long array[100], n, c;
printf("Enter number of elements\n");
scanf("%ld", &n);
scanf("%ld", &n);
printf("Enter %ld integers\n", n);
for (c = 0; c < n; c++)
scanf("%ld", &array[c]);
scanf("%ld", &array[c]);
bubble_sort(array, n);
printf("Sorted list in ascending order:\n");
for (c = 0; c < n; c++)
printf("%ld\n", array[c]);
printf("%ld\n", array[c]);
getch();
}
}
void bubble_sort(long list[], long n)
{
long c, d, t;
{
long c, d, t;
for (c = 0 ; c < n - 1; c++) {
for (d = 0 ; d < n - c - 1; d++) {
if (list[d] > list[d+1]) {
/* Swapping */
t = list[d];
list[d] = list[d+1];
list[d+1] = t;
}
}
}
}
for (d = 0 ; d < n - c - 1; d++) {
if (list[d] > list[d+1]) {
/* Swapping */
t = list[d];
list[d] = list[d+1];
list[d+1] = t;
}
}
}
}
