Assignment 2

This program will be a modification of the program done in CISS 241, Week 7 Programming Assignment 1. That was the Rainfall Statistics program. For those who did not take 241, that program description is below. Modify the Rainfall Statistics program so that it displays a list of months, sorted in the order of rainfall from highest to lowest.

 

I keep getting errors and can't figure out why.  I've declared the variables, int and strings but later in the code it states not declared.  

Rainfall isn't sorted properly and continues to give me numbers at the end of the month between 0 and 11, instead of the entered rainfall amounts.  Please help.
