Question

Write a C++ console application that allows your user to capture rainfall statistics. Your program should contain an array of 12 doubles for the rainfall values as well as a parallel array containing the names of the months. Using each of the month names, prompt your user for the total rainfall for that month. The program should validate user input by guarding against rainfall values that are less than zero. After all 12 entries have been made, the program should display a list of the months and their corresponding rainfall values sorted in order by rainfall, from highest to lowest.

Submit two files. A word processing file with your answers to the five Questions and a compressed file containing your solution to the Programming Exercise. Remember to submit them both at the same time.

Answer 1

Please find the code below::

#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
int main()
{

   string months[12] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
   double rainFall[12];
   for(int i=0;i<12;i++){
       cout<<"Enter rain fall for month "<<months[i]<<" : ";
       cin>>rainFall[i];
       while(rainFall[i]<0){
           cout<<"Error!!! Value should be greater than zero"<<endl;
           cout<<"Enter rain fall for month "<<months[i]<<" : ";
           cin>>rainFall[i];
       }
   }

   //doing sorting
   for(int i=0;i<12;i++){
       for(int j=0;j<12;j++){
           if(rainFall[i]>rainFall[j]){
               double temp = rainFall[i];
               rainFall[i] = rainFall[j];
               rainFall[j]= temp;

               string name = months[i];
               months[i] = months[j];
               months[j]= name;
           }
       }
   }

   cout << setw(18) << left << "Month name";
   cout << setw(18) << left << "Rain";
   cout<<endl;
   for(int i=0;i<12;i++){
       cout << setw(18) << left << months[i];
       cout << setw(18) << left << rainFall[i];
       cout<<endl;
   }

   return 0;
}

output:
