I am in dire need of help. I need this array to list the months as the user enters rainfall totals. then I need it to calculate the highest , lowest , average and total rainfall months. I can get it to do it without the months but not with the months. It also cannot accept negative numbers. can anyone help me.
//This program lets the user enter the total rainfall for each of the 12 months
//into an array of doubles . the program should calculate and display the total
//rainfall for the year , the average monthly rainfall , and
//the months with the highest and lowest amounts

#include <iomanip>
