1. Declare a constant tuple that contains three Int values followed by a Double. Use this to represent a date (month, day, year) followed by an average temperature for that date.
2. Change the tuple to name the constituent components. Give them names related to the data that they contain: month, day, year and averageTemperature.
3. In one line, read the day and average temperature values into two constants. You’ll need to employ the underscore to ignore the month and year.
4. Up until now, you’ve only seen constant tuples. But you can create variable tuples, too. Change the tuple you created in the exercises above to a variable by using var instead of let. Now change the average temperature to a new value.
