Introduction:

The objective of this lab is to create a temperature sensor simulator. First the program must ask the  user to identify what season to simulate . 1 for winter. 2 for spring. 3 for summer, and 4 for fall or 5 to exit. After the season is selected, the program will ask the user how many time he want to simulate. Each simulation will produce a random numbers as follows: for winter a number between 20-40, for spring between 40-70, for summer between 70-90, and for fall between 40-60.

We must then display this results to the user. The Program must run until the user exits it.

1-      First temperature generated

2-      Last temperature generated

3-      Lowest temperature generated

4-      Highest temperature generated

5-      Total sum of all temperatures generated

6-      Average for the season
