Using classes, new, and delete. Lets create a program representing a model train. We will need:

-a train class to represent the whole train that contains: a pointer to the engine.

-a car class for each train car with: cargo weight (this can be an int), a pointer to the next car so we can access each car.

-a way to know we are at the caboose..

create a train

-new train()

-creates 3 cars and gives them a weight value

-insert the car into the train as it is created: make sure the previous car is pointing to the new car

-Delete the train

- use a destructor to delete the train

-make sure you free all memory by iterating through the train cars.

Please use c++.
