Lab Description:
In this lab we were asked to create a temperature sensing program that generates random temperatures for each season. The user is asked to enter the desired season and the number of simulations. The program then tracks the highest, lowest, first and last temperatures for each simulation and calculates the total and average temperatures for each session. After the simulations are done the program will output the results and repeat the main menu if the user decides to continue.
