  4. int main()
  5. {
  6. int numb, originalNumb, r, result = 0, n = 0 ;
  7. printf("Enter an integer: ");
  8. scanf("%d", &numb);
  9. originalNumb = numb;
  10. while (originalNumb != 0)
  11. {
  12. originalNumb /= 10;
  13. ++n;
  14. }
  15. originalNumb = numb;
  16. while (originalNumb != 0)
  17. {
  18. r = originalNumb%10;
  19. result += pow(r, n);
  20. originalNumb /= 10;
  21. }
  22. if(result == numb)
  23. printf("%d is an Armstrong number.", numb);
  24. else
  25. printf("%d is not an Armstrong number.", numb);
