Question

Reimplement the class using a simple counter that is advanced in each call to next?

Answer 1

A class with a simple counter can be implemented by adding a private numeric attribute which is incremented in the next method call. This will track the number of times the method is invoked.

Step-by-step explanation:

The student's question pertains to the reimplementing of a class that uses a counter to keep track of calls to the next method. A typical approach to do this would involve having a private variable in the class to serve as the counter. Each time the next method is called, this counter would be incremented.

Here's a simple example in Python:

class CounterIterator:
def __init__(self):
self._counter = 0

def next(self):
self._counter += 1
return self._counter

In this example, CounterIterator is a class with an initialization method and a next method. The _counter attribute is initialized to zero, and each time next is called, _counter is incremented by one and its new value is returned
