Write a full class definition for a class named Counter, and containing the following members: A data member counter of type int. A constructor that accepts no arguments and initializes the counter data member to 0. A function called increment that accepts no parameters and returns no value. increment adds one to the counter data member. A function called getValue that accepts no parameters. It returns the value of the instance variable counter.

LANGUAGE: C++

CHALLENGE:

Write a full class definition for a class named Counter, and containing the following members:
A data member counter of type int.
A constructor that accepts no arguments and initializes the counter data member to 0.
A function called increment that accepts no parameters and returns no value. increment adds one to the counter data member.
A function called getValue that accepts no parameters. It returns the value of the instance variable counter.

SOLUTION:




class Counter{
    private:
        int counter;
    public:
        Counter(int preset);
        void increment();
   void decrement();
        int getValue();
};

Counter::Counter(int preset){
    counter=preset;
}

void Counter::increment(){
    counter++;
}

void Counter::decrement(){
    counter--;
}

int Counter::getValue (){
 return counter;
}
