  int number5 = 54, number6 = 63, number7 = 72, number8 = 81, number9 = 90;

  long sum = 0L;                                 /* Sum of the numbers          */
  float average = 0.0f;                          /* Average of the numbers      */

  sum = number0 + number1+ number2 + number3 + number4+
           number5 + number6 + number7 + number8 + number9;
   average = (float)sum/10.0f;

   printf("Average of the ten numbers entered is: %f", average);
