1. Modify the program to calculate and display the sum of rainfall for each year. And to calculate and display the monthly average for that year. (Hint: this is NOT part of the input.) You have all the data collected. You need to sum the monthly rainfall that you already collected during the input. You can do this during the output function PrintData or you can create a separate function to do the sum. Support your experimentation with screen captures of executing the new code showing ALL the output.

2. Enhance the program to allow the user to enter another meteorological element such as snowfall or windspeed (e.g. 2.4 mph). (Hint: you will need another array). Note, the user should be able to enter both rainfall and the 2nd meteorological element in your new implementation. You will need to update the InputData and PrintData functions. Support your experimentation with screen captures of executing the new code showing ALL the output.

3. Modify the program to calculate and display the sum of your 2nd meteorological element for each year. And to calculate and display the monthly average for that year. (Hint: this is NOT part of the input.) You have all the data collected. You need to sum the monthly rainfall that you already collected during the input. You can do this during the output function PrintData or you can create a separate function to do the sum or you can do it at the same time as you do the rainfall Support your experimentation with screen captures of executing the new code showing ALL the output.

4. Prepare a new test table with at least 2 distinct test cases listing input and expected output for the code you created after step 3. You need to only show the input and output for the first and last year of each test case.

5. Modify the program so that it will prompt and calculate and display 5 years of your two meteorological elements. Support your experimentation with screen captures of executing the new code. Showing ALL the output.
