The for loop. 8. A counter variable is used to control or keep track of the number of times a loop. iterates. In a loop, the counter is usually incremented or decremented. If the. counter variable is not properly initialized, it will not hold the correct number. 9. An accumulator is used to keep a running total of numbers. In a loop, a value is. usually added to the current value of the accumulator.

This internal register is then read periodically to determine how many events have occurred. Typically used to measure frequency or RPM, accumulate pulses from a tipping bucket precipitation (rain) gauge, and similar counting applications.
