Increment a Counter

private:
   int count;
public:
   DeviceCounter(int c = 0) : count(c) {}
   // your code here: define prefix ++ operator to increment count

        return *this;
    }
   int getCount() const {
       return count;

};

int main() {

   cin >> n;
   DeviceCounter counter;
   for (int i = 0; i < n; i++) {
       ++counter; // must use overloaded operator
   }
   cout << "Final count=" << counter.getCount();
   return 0;
