    Perhaps a while loop, (straight from my own Turbo C/C++ compiler )

    #include <stdio.h>
    int main(void)   {
       long number;
       int sum, c;
       /* get your number up here */
       sum = 0;
       while(number > 0)   {
          sum += number &#37; 10;  /* same as sum = sum + number % 10 */
          number /= 10;              /* same as number = number / 10 */
          printf("\n  sum = %d, number = %ld ", sum, number);
       printf("\n\n\t\t\t  Hit Enter When Ready ");
       while((c = getchar()) != '\n');
       c = getchar();
       return 0;

    Me too, I saw that and thought "Man that's familiar, I remember that IDE," and shivered in disgust.
