-- 1. Write a stored procedure that given a Celsius temp returns a Fahrenheit.
-- F = (9/5.0) * C + 32

-- 2. Write a stored procedure to print out a list of C to F where C goes
-- from 1 to 100.
-- =============================================================================
--second problem

-- 3. Write a stored procedure that given a city will return author’s first
-- and last names from the pub database that live in that city.
-- (note: create the code in your database accessing tables in pubs as
-- pubs..tablename).
-- =============================================================================
--third problem

-- 4. Modify the previous code to display the title that they wrote too.

-- 5. Write a stored procedure that given a city returns the total number of
-- authors that live in that city through an output parameter.
