In C++

Vehicles are classified by type; compact cars, luxury cars, trucks and wagons ( 4 types). - For cars and vans, it is also important to store the number of passengers. - Luxury cars must also indicate whether they are hybrids or not. - For trucks, the load capacity in kgs must be controlled. and the number of axles. It adds a parameterized constructor to each class to initialize its data and calls the constructor of the base class from the constructor of each derived class, that is, only 4 objects corresponding to the derived classes are created
