Template Method Calls a Virtual

A non-virtual base method can call a virtual method, and overriding that virtual changes the base method's behavior. The Report class has a Build() method that wraps a Body() between a header and footer, and Body() is virtual returning Empty. Override Body() in SalesReport so it returns Sales data. Do NOT write a Main method.

The program prints:
Header
Sales data
Footer

Expected Output:

Header
Sales data
Footer
