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

If you are going to plagerize someone else's program then at least change the function names so that people will think you write it for your homework assignment.

there is a program like this please could you link it so I can see the example , I pulled these from examples from my book, as per my instructions. I am looking for a good example .I do intend to fully rewrite this as it is a work in progress. I just am not interested in doing like most of my class is doing and searching online for a program coping pasting . I need help on a few sections of this program that I pulled from the book as , I was told to do. once I figure out how to code it I will do so. just needed to know how to get the string array to work with the double testscores [SIZE ]array and getting the if statement to work correctly is all.
thanks for the reply

If you know the index number for testscores[] then just use the same number for the string array. For example consider this code snippet

int highest = GetHightest(...); // where ... are the parameters

cout << "Highest is " << testscores[highest];
cout << "month is " << months[highest];
