Program 110: Short Time III

Program 110: Short Time III

Program 109 has been fixed. Now the delay is closer to what we expect. Not exactly what we expect, but close. What's happening now?

  1 /***********************************************
  2  * bit_delay -- Delay one bit time for         *
  3  *      serial output,                         *
  4  *                                             *
  5  * Note: This function is highly system        *
  6  *      dependent.  If you change the          *
  7  *      processor or clock it will go bad.     *
  8  ***********************************************/
  9 void bit_delay(void)
 10 {
 11     int i;      // Loop counter
 12     volatile int result;// Result of the multiply
 13
 14     // Factors for multiplication
 15     int factorl = 12;
 16     int factor2 = 34;
 17
 18     // We know that 1863 multiplies
 19     // delay the proper amount
 20     for (i = 0; i < 1863; ++i)
 21     {
 22         result = factor1 * factor2;
 23     }
 24 }

(Next Hint 95. Answer 39.)

1 is equal to 2 for sufficiently large values of 1.
