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 the output shown in Expected Output.

Expected Output:

Header↵
Sales data↵
Footer↵

= newline. The output ends with a newline — print one after the last line.
