Problem Statement:

In continuation of Assignment No. 1 and 2, we have the following part of class diagram:

Car, SUV and HDV are concrete classes as opposed to Vehicle with a pure virtual function.

You are required to implement polymorphism in the above scenario by writing a complete C++ program with the mentioned data members and member functions.

In the main function, create one object each of Car, SUV and HDV and call their respective showGears() function thus implementing the concept of polymorphism.

Following is the sample output that you need to print:

---Sample Output---Good Luck.
