Question
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.

Explanation / Answer
class Counter:
def __init__(self,counter=0,limit=0):
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
e = Counter(1,6)
print(e.get_value())
e.increment()
print(e.get_value())
e.decrement()
print(e.get_value())
