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.

A data member named limit of type int.

A static int data member named nCounters that 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 $0,$ 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.

Note: Don't use the #include "Counter.h$",$ because REVEL assumes that your Counter header is in the same file with the implementation. You need to initialize static data member nCounters as

int Counter::nCounters $=0$;

This line has to be put as the first line in your code.
