Rainfall Review and Assistance

[maenielwolf]

This is my program so far. I am having trouble getting the program to sort and display the array based on the rainfall data entered and the month which it was entered in. I have the program where it sorts the numbers entered for rainfall but cant seem to be able to get the month name to stay with the number it correlates to. Would also like to know how to make the two columns of data line up if anyone could answer that as well. Thanks in advance.

This program was an assignment but I have sense turned it in and received a final score. I asked my professor where I went wrong and got no response hence me putting it on here so I can hopefully learn how to improve.

***************************************

Here are the original instructions for the Rainfall Program:

Write a program that lets the user enter the total rainfall for each of 12 months into an array of doubles. The program should use two 12 element arrays. One array will hold strings, the names of the 12 months. This array will be initialized when the array is created using an initialization list (could also be created as a array of constants). The second array will hold doubles which will be the total rainfall for each month. The program will prompt the user for the rainfall for each month (using both arrays) and store the value entered into the array with the rainfall totals, the other is used to display which month the program is asking for the rainfall total. The program should display the following once the data is all entered:

The total rainfall for the year
The average monthly rainfall
The month with the highest amount of rainfall (must display the month as a string)
The month with the lowest amount of rainfall (must display the month as a string)

The program must have the following functions:

double getTotal(double [ ], int);
double getAverage(double [ ], int);
double getLowest(double [ ], int, int&); //returns the lowest value, provides the index of the lowest value in the last parameter.
double getHighest(double [ ], int, int&); //returns the highest value, provides the index of the highest value in the last parameter.

Modify the Rainfall Statistics program so that it displays a list of months, sorted in the order of rainfall from highest to lowest.

In your sort function you also need to swap the month names when you swap the temperatures.
Also you could simplify your getHighest and getLowest functions when save your arrays first.
