  1. // C program to sort an array using Insertion Sort
  2. #include <stdio.h>
  3. int main()
  4. {
  5. int n, arr[100], i, j, t;
  6. printf("Enter number of element: ");
  7. scanf("%d", &n);
  8. printf("Enter elements: " );
  9. for (i = 0; i < n; i++)
  10. {
  11. scanf("%d", &arr[i]);
  12. }
  13. for (i = 1 ; i <= n - 1; i++)
  14. {
  15. j = i;
  16. while ( j > 0 && arr[j-1] > arr[j])
  17. {
  18. t = arr[j];
  19. arr[j] = arr[j-1];
  20. arr[j-1] = t;
  21. j--;
  22. }
  23. }
  24. printf("Sorted array: ");
  25. for (i = 0; i <= n - 1; i++)
  26. {
  27. printf("%d ", arr[i]);
  28. }
