PP 4.1 Write a class called Counter that represents a simple tally counter, which might be used to count people as they enter a room. The counter class should contain a single integer as instance data, representing the count. Write a constructor to initialize the count to zero. Write a method called click that increments the count and another method called getcount that returns the current count. Include a method called reset that resets the counter to zero. Finally, create a driver class called CounterTest that creates two counter objects and tests their methods.
