Subject Write a complete C++ program and implement the class vehicle in Figure 1 Detailed members of three classes are given below. Note the comprehensive constructor is a constructor for a subclass that provides parameter for Vehicle Car Truck initializing properties of both current class and all ancestor classes. Each class Figure 1 is made of one header file and one source file Class Vehicle Proerties (private) speed: double o weight: double Constructors non-argument constructor: initialize this class's properties with default values class. It initializes this class's properties with parameters property, no parameter, usually made of one return statement, for reading value of the o standard constructor: number of parameters equals to the number of properties of this o one get method for each private property: same return type as the corresponding o one set method for each private property: void return type, one parameter, for resetting o displayO: no return, no parameter, print name and current value of every property . Methods property value of the property using the parameter from outside of the class. It is usually made of one assignment statement o start0: no return, print how a typical vehicle usually starts. For example, start with key and ignitor Class Car * Properties (private o color: string o model: string
