Write the implementation (.cpp file) of the Counter class of the previous exercise.

LANGUAGE: C++

CHALLENGE:

Write the implementation (.cpp file) of the Counter class of the previous exercise. The full specification of the class is:

A data member  counter of type int.
An data member named limit of type int.
A static  int data member named  nCounters which is initialized to 0.
A constructor that takes two  int arguments and assigns the first one to  counter and the second one to limit. It also adds one to the static variable nCounters
A function called  increment that accepts no parameters and returns no value. If the data member  counter is less than  limit, increment just adds one to the instance variable counter.

A function called decrement that accepts no parameters and returns no value. If counter is greater than zero, decrement subtracts one from the  counter.
A function called getValue that accepts no parameters. It returns the value of the instance variable counter.
A static function named getNCounters that accepts no parameters and return an int. getNCounters returns the value of the static variable nCounters.
