P9.18 Define a class ComboLock that works like the combination lock in a gym locker, as shown here. The lock is constructed with a combinationthree numbers between 0 and 39. The reset function resets the dial so that it points to 0. The turn left and turn right functions turn the dial by a given number of ticks to the left or right. The open function attempts to open the lock. The lock opens if the user first turned it right to the first number in the combination, then left to the second, and then right to the third. class ComboLock { public: ComboLock(int secreti, int secret2, int secret3); void reset(); void turn_left(int ticks); void turn_right(int ticks); bool open() const; private: }
