-- Homework 13, challenge: Hypotenuse.
--
-- Given a and b (the two short sides of a right triangle), compute
-- the hypotenuse c using:

-- Print all three values with labels. Round c to two decimals using
-- string.format with %.2f.
--
-- Run with: lua exercises/13/homework/04-hypotenuse.lua

local a = 3
local b = 4
