Adding DailySummary objects to a WeatherStation 1. Write a WeatherStation::add that adds a DailySummary object to the station. a. you may not add a null DailySummary b. you may not add a DailySummary for the same date (month, day, and year) as an already-added DailySummary 2. Your WeatherStation::add method must handle the following test cases: a. any and all precondition checks b. adding a DailySummary with a date that is a duplicate of an already-added DailySummary c. adding a single DailySummary d. adding multiple DailySummary objects Find the hottest day recorded at the WeatherStation 1. Write a WeatherStation::findHottestDay that
