Write a program for bubble sort using arrays.

#include <stdio.h>
#define MAX 20
main()
{
int arr[MAX],i,j,k,temp,n,xchanges;
printf("Enter the number of elements : ");
scanf("%d",&n);
for (i = 0; i < n; i++)
{
printf("Enter element %d : ",i+1);
scanf("%d",&arr[i]);
}
printf("Unsorted list is :\n");
for (i = 0; i < n; i++)
printf("%d ", arr[i]);
printf("\n");

/* Bubble sort*/
for (i = 0; i < n-1 ; i++)
{
xchanges=0;
for (j = 0; j <n-1-i; j++)
{
if (arr[j] > arr[j+1])
{
temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
xchanges++;
}/*End of if*/
}/*End of inner for loop*/
if(xchanges==0) /*If list is sorted*/
break;
printf("After Pass %d elements are :  ",i+1);
for (k = 0; k < n; k++)
printf("%d ", arr[k]);
printf("\n");
}/*End of outer for loop*/

printf("Sorted list is :\n");
for (i = 0; i < n; i++)
printf("%d ", arr[i]);
printf("\n");
}/*End of main()*/
