C program for bubble sort:

 

#include <stdio.h>

int main()

{

     int i, j, num, arr[250], swap;

 

     printf("Please enter the number of elements\n");

     scanf("%d", &num);

 

     printf("Enter %d numbers\n", num);

     for (i = 0; i < num; i++)

          scanf("%d", &arr[i]);

 

     for (i = 0 ; i < ( num - 1 ); i++)

     {

            for (j = 0 ; j < num - i - 1; j++)

            {

                     if (arr[j] > arr[j+1]) /* For decreasing order, please use < */

                     {

                              swap     = arr[j];

                              arr[j]   = arr[j+1];

                              arr[j+1] = swap;

                     }

            }

     }

 

     printf("Bubble sorting in ascending order:\n");

 

     for ( i = 0 ; i < num ; i++ )

          printf("%d\n", arr[i]);

 

     return 0;

}

 

Output:
