Use C++ - Create a base class called **Vehicle** that has the manufacturer's name (type **string**), number of cylinders in the engine (type **int**), and owner (type **Person**).- Then create a class called **Truck** that is derived from **Vehicle** and has additional properties: the load capacity in pounds (type **int**).- Be sure your classes have constructors, a copy constructor, accessor, and mutator functions.- Write a main function that tests all your member functions.
