int AddDecDigits (int number)
// precondition: number is not negative
// postcondition: returns the sum of the decimal digits in number
{
   int result = 0;

   // for each digit in number
   while (number > 0)
   {
      result += (number % 10);      // body: add current digit to sum
      number /= 10;                 // update: march number toward zero
   }

   // OR:
   // for ( ; number > 0; number /= 10)
   // {
   //    result += (number % 10);
   // }

   return result;
