How do you find the execution time?
1) Create a loop around whatneeds to be measured, that executes 10, 100, or 1000 times or more. Measure execution time to the nearest 10 msec. Then divide that time bythe number of times the loop executed. If the loop executed 1000 timesusing a 10 msec clock, you obtain a resolution of 10 µsec for theloop.
