This also allows you to store pointers to objects of the derived class types PassCar and Truck. The objects themselves will be created dynamically at runtime. Define a class CityCar with an array of pointers to the Car class and an int variable for the current number of elements in the array. The constructor will set the current number of array elements to 0. The destructor must release memory allocated dynamically for the remaining objects. Make sure that you use a virtual destructor definition in the base class Car to allow correct releasing of memory for trucks and passenger vehicles....
