COS 160- Weather Analysis

Part 1:

In Program 9 you wrote methods to work on arrays. Copy those methods into this program and use them to calculate and print:

The highest temperature in tmax and the date it occured on (use arrayMax(), arrayFirstIndexOf(), and then use that index for your month[], day[], and year[] arrays)

The lowest temperature in tmin and the date it occured on

The average tmax (As a check, your value should be 55.596... If you are not getting this value, there is something wrong with your code.)

The average tmin

Code:
