(17 pts) Inheritance. Write a complete Truck class based on the UML provided. The Truck class is a subclass of the Vehicle class. The Vehicle class is listed on the last page of this exam. Your Truck implementation must utilize inheritance features 8. Truck -weight:int +Iruck() //the weight of a truck //constructor. default weight -e +Truck (somevin:string, wint) //constructor.
