Question

Rainfall Statistics
Write a modular program that analyzes a year's worth of rainfall data. In addition to main, the program should have a getData function that accepts the total rainfallfor each of 12 months from the user, and stores it in a double array. It should also have four value-returning functions that compute and return to main thetotalRainfall, averageRainfall, driestRainfall, and wettestMonth. These last two functions return the number of the month with the lowest and highest rainfall amounts,not the amount of rain that fell those months. Notice that this month number can be used to obtain the amount of rain that fell those months. This information shouldbe used either by main or by a displayReport function called by main to print a summary rainfall report similiar to the following:

2010 Rain Report for Neversnows County

Total rainfall : 23.19 inches
Average monthly rainfall : 1.93 inches
The least rain fell in January with 0.24 inches.
The most rain fell in April with 4.29 inches.

Input validation: Do not accept rainfall amounts less than 0.


please make sure, the program includes all of the details, all functions asked for and do what is asked and a report as the one above is printed in the window and alsomake sure the program runs with no errors.

Answer 1

Does the program compile? If so, does it produce the output you expected? Does it have all of the functions it is required to have? If sample data isprovided, does the program produce the expected output for a given set of inputs? These are all questions you should ask yourself when you want to know ifyour assignment is "done".

I would think that driestMonth and wettestMonth would both return ints instead of doubles. Also, your avgRainfall function is wrong. You should use atemporary variable to store the sum of the rainfall, and that variable should be of type double. The average should also be of type double, and is found bydividing the sum of all the rainfall by 12.

There may be other problems that I failed to notice (I'm a bit tired, sorry)

Answer 2

Dear user,
Here is the c++ code below;

//Header file section
#include<iostream>
using namespace std;

//Start main
int main()
{
//Declare variables
const int N_MONTHS = 12;
int rain;
int values[N_MONTHS];
const int STRING_SIZE=15;
double total = 0;
double avg;
int largest,lmonth;
int smallest,smonth,count;
//Array with the names of the months
char p_months[N_MONTHS][STRING_SIZE] = { "January",
"February", "March",
"April","May","June", "July",
"August", "September", "October",
"November", "December" };
for ( int month = 1; month <= N_MONTHS; month++ )
{
//Get monthly total rainfall from user
cout<<"Enter the total rainfall for "<<p_months[month-1]<<":";
cin >>rain;
//input validation
if ( rain < 0 )
{
cout << "You enter negative number.try again" << endl;
cout << "Please reenter: ";
cin >> rain;
}
values[month-1]=rain;
total += rain;
} //Get the monthly rainfalls
cout << "nTotal rainfall: " << total <<" inches" << endl;
// Calculate the average amount of rainfall
avg = total / (double)N_MONTHS;
cout << "Average monthly rainfall: "<< avg << "inches"<< endl;
for ( int month = 1; month <= N_MONTHS; month++ )
{
largest = values[0];
//logic to find largest
for ( count = 1; count < N_MONTHS; count++ )
{
if ( values[count] > largest )
{
largest = values[count];
lmonth=count;
}
}


smallest = values[0];
//logic to find smallest
for ( count = 1; count < N_MONTHS; count++ )
{
if ( values[count] < smallest )
{
smallest = values[count];
smonth=count;
}

}
}

// Disply the highest and lowest rainfall
cout << "The most rain fell in " << p_months[lmonth]<< endl;

cout << "The least rain fell in " <<p_months[smonth]<< endl;

//pause system for a while
system("pause");
return 0;
}

//end main

Output:
