Question

Python

Write the definition of a class Counter containing:

• An instance variable named counter of type int
• An instance variable named limit of type int.
• A constructor that takes two int arguments and assigns the first one to counter and the second one to limit
• A method named increment. It does not take parameters or return a value; if the instance variable counter is less than limit, increment just adds one to the instance variable counter.
• A method named decrement. It also does not take parameters or return a value; if counter is greater than zero, it just subtracts one from the counter.
• A method named get_value that returns the value of the instance variable counter.

Answer 1

class Counter:
    def __init__(self, counter, limit):
        self.counter = counter
        self.limit = limit

    def increment(self):
        if self.counter < self.limit:
            self.counter += 1

    def decrement(self):
        if self.counter > 0:
            self.counter -= 1

    def get_value(self):
        return self.counter
