Q1. Consider a hierarchy of classes representing vehicles. The base class is Vehicle, and there are two intermediate derived classes, LandVehicle and WaterVehicle. LandVehicle has a derived class, Car, while WaterVehicle has a derived class, Boat. All classes have a drive() method which is overridden in the derived classes. The base class, Vehicle, should be an abstract class. Implement the above hierarchy of classes in C++. You can use any appropriate access modifiers, data members and member functions as deemed necessary. Make sure to use virtual functions where appropriate to allow polymorphic behavior. Write a main program that creates a vector of base class pointers, pointing to objects of each class (use dynamic memory allocation). The program should then iterate over the vector and call the appropriate drive() method on each object, outputting the result. Finally, the program should deallocate the objects to avoid memory leaks [Hint: delete operator can be used in a for loop].

Q1. Consider a hierarchy of classes representing vehicles. The base class is Vehicle, and there are two
intermediate derived classes, LandVehicle and WaterVehicle. LandVehicle has a derived class, Car,
while Water Vehicle has a derived class, Boat. All classes have a drive() method which is overridden
in the derived classes. The base class, Vehicle, should be an abstract class.
Implement the above hierarchy of classes in C++. You can use any appropriate access modifiers, data
members and member functions as deemed necessary. Make sure to use virtual functions where
appropriate to allow polymorphic behavior.
Write a main program that creates a vector of base class pointers, pointing to objects of each class
(use dynamic memory allocation). The program should then iterate over the vector and call the
appropriate drive() method on each object, outputting the result. Finally, the program should
deallocate the objects to avoid memory leaks [Hint: delete operator can be used in a for loop].

Please read requirement carefully. DO NOT COPY AND PASTE FROM OTHER SOLUTION AVAILABLE ONLINE There are two players adding words to a growing word fragment. Each player will take turns attempting to add letters to a growing word fragment. The letter you select should attempt to force your opponent to spell a word or create a word fragment that has no possibility of creating a word. Unlike the prior ghost competition, when it is your turn you are allowed to add a letter to either the front or back of the word fragment.Winning Criteria:If your opponent spells a word that is at least 6 characters longif your opponent creates a word fragment that has no possibility of creating a wordif your opponent takes longer than 60 seconds to select a word.Tip: If you are the first player you can only spell words that are odd length thus you can only lose when you spell words that are odd but you can win when your opponent spells words that are even length. Accordingly, if you are the first player you…
