Using the Override Keyword

Create a base class Bird with a virtual method string sound() const that returns "generic".

Create a derived class Sparrow that overrides sound() to return "chirp". Mark the override with the override keyword.

When called through a Bird* that points to a Sparrow, the program prints the output shown in Expected Output.

Do NOT write a main function.

Expected Output:

chirp↵

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