Rainfall Statistics

Write a program that lets the user enter the total rainfall for each of 12 months (starting with January) into an array of doubles. The program should calculate and display (in this order):


  • the total rainfall for the year,
  • the average monthly rainfall,
  • and the months with the highest and lowest amounts.


Months should be expressed as English names for months in the Gregorian calendar, i.e.: January, February, March, April, May, June, July, August, September, October, November, December.


Input Validation: Do not accept negative numbers for monthly rainfall figures. When a negative value is entered, the program outputs "invalid data (negative rainfall) -- retry" and attempts to reread the value.

NOTE: Decimal values should be displayed using default precision, i.e. do not specify precision.


SAMPLE RUN #1: ./ETest

Make sure it will run with the correct output. Ty!

Answer #1

Screenshot of the code:

#include <iostream> #include <string> using namespace std; int main() { //An array of strings is initialized. // The months atotal_rainfall += rainfall[i]; //Calculate the minimum rainfall. if(rainfall[i] < rainfall[min rainfall]) min_rainfall = i; /Sample Output:

Enter rainfall for January: 25.5 Enter rainfall for February: 22 Enter rainfall for March: 12, Enter rainfall for April: 10 E

Code to copy:

#include <iostream>

#include <string>

using namespace std;

int main()

{

//An array of strings is initialized.

//The months are stored in the memory allocated to the string //array: months

string months[] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};

//initialize an array to store the rainfall of 12 months

double rainfall[12] = {-1};

//initialize a variable to store total rainfal

double total_rainfall = 0;

//initialize the variable min_rainfall to store the minimum rainfall

int min_rainfall = 0;

//initialize the variable max_rainfall to store the maximum rainfall

int max_rainfall = 0;

//Prompt the user to enter the rainfall for 12 months one by one.

for(int i = 0; i < 12; ++i)

{

cout << "Enter rainfall for " << months[i] << ": ";

cin >> rainfall[i];

//If the monthly rainfall figures are in negative numbers, the program outputs /invalid data. The value is re-read.

while(rainfall[i] < 0)

{

cout << "Invalid data (Negative rainfall) -- retry" << endl;

cout << "Enter rainfall for " << months[i] << ": ";

cin >> rainfall[i];

}

//The value of total rainfall is calculated

total_rainfall += rainfall[i];

//Calculate the minimum rainfall.

if(rainfall[i] < rainfall[min_rainfall])

{

min_rainfall = i;

}

//Calculate the maximum rainfall

else if(rainfall[i] > rainfall[max_rainfall])

{

max_rainfall = i;

}

}

//Print total rainfall

cout << "Total rainfall: " << total_rainfall << endl;

//calculate the average rainfall

double average_rainfall = total_rainfall / 12.0;

//Print average rainfall

cout << "Average rainfall: " << average_rainfall << endl;

//Print the month which has recorded minimum rainfall

cout << "Least rainfall in: " << months[min_rainfall] << endl;

//Print the month which has recorded maximum rainfall

cout << "Most rainfall in:" << months[max_rainfall] << endl;

}
