Rewrite the shapes assignment, with the following modifications:
Each shape must be represented by a class. The members of the class will be the dimensions of the shapes which will be private.
You will need member functions (methods) to calculate volume and surface area as well as a get and set function to retrieve the member values and set them. The set function must prohibit the user from entering negative values for a dimension.
You will also need a constructor for each class to set the default values.
You may optionally include an input and display function as well.
Refer to the original shapes assignment for all other requirements.
