insertion sort in c

Insertion sort in c: c program for insertion sort to sort numbers. This code implements insertion sort algorithm to arrange numbers of an array in ascending order. With a little modification it will arrange numbers in descending order.

/* insertion sort ascending order */

#include<stdio.h>

main()

{

   int array[100], n, c, d, swap, k;

   printf("Enter number of elements\n");

   scanf("%d", &n);

   printf("Enter %d integers\n", n);

   for ( c = 0 ; c < n ; c++ )

       scanf("%d", &array[c]);

   for ( c = 1 ; c <= n - 1 ; c++ )

   {

       for ( d = 0 ; d <= c - 1 ; d++ )

       {

           if ( array[c] < array[d] )

           {

              swap = array[d];

              array[d] = array[c];

              for ( k = c ; k > d ; k-- )

                 array[k] = array[k-1];               

              array[k+1] = swap;

           }

       }

   }

   printf("Sorted list in ascending order:\n");

   for ( c = 0 ; c < n ; c++ )

       printf("%d\n", array[c]);

   return 0;
