oracle - How to output result of SELECT statement which is executed using native dynamic SQL?

I have a string which contains SQL SELECT statement.
I wonder how can I output result of the execution of that statement on the screen, execution will be done using native dynamic SQL (EXECUTE IMMEDIATE).

example:

DECLARE
v_stmt VARCHAR2 := 'SELECT * FROM employees';
BEGIN
EXECUTE IMMEDIATE v_stmt; -- ??? how to output result of that select on the screen.
END;

Important remark: structure of table can be any. I have to write a procedure which accepts name of the table as parameter, so I can't hardcode a table structure and don't want to do it.

Thanks for responses. Any ideas very appreciated/
