Description:

This lab is used to simulate seasonal temperature.

The user will enter a season, and number of trial of number will be executed.

This program will print out the following:
1. first generated data
2. last generated data
3. highest generated data
4. lowest generated data
5. sum of generated data
6. average of generated data

Code:
