/* Reads temperatures from the user and computes average temperature.  Lastly
   Reports # days above average, all temperatures entered, and highest and 
   lowest temperatures.
Example output:

How many days' temperatures? 7
Day 1's high temp: 45
Day 2's high temp: 44
Day 3's high temp: 39
Day 4's high temp: 48
Day 5's high temp: 37
Day 6's high temp: 46
Day 7's high temp: 53
Average temp = 44.6
4 days were above average.

Temperatures: [45, 44, 39, 48, 37, 46, 53]
Coldest day: 37
Hottest day: 53
