arrays -- HELP

[abcdefg]

Hi,

When I was reading a book about arrays in C++, I  got a doubt about how we should create a report .

In other words, if the problem is like  a metrologist wants to keep track of the 3 seasons in the last year, whether they are sunny, rainy or cloudy.

Then I took a 3 x 30 array. (He doesn't want to record the 31st of any month)

3 -->  months --> June, July,August.
30 --> days. (1,2,3-------30)

The data is being read by a .dat file.

Then the program should create a report that displays
 for each month and for the whole 3 month period ,
how many days were rainy , how many were cloudy,
and how many were sunny.

It should also report which of the 3 months
 had the largest number of rainy days.

I got blank when I saw creating a report. Can some one please....please explain me how can I go further in my program.

Thanks......

Post what code you've come up with so far, and it will be easier to understand and help you.

Are you perhaps trying to acess an element in the array that doesn't exist?

This is my code so far. The out put is , the data from the .dat file.

Code:

#include <iostream>
#include<fstream>
#include<string>


using namespace std;

int main()
{   
      char NUM_MONTHS  = 3;
    // string name[NUM_MONTHS] = {"June","July","August");
      char NUM_DAYS = 30;
     char rainorshine [NUM_MONTHS][NUM_DAYS];
     int month ,count ;
     ifstream datafile;
     datafile.open("RainOrShine.dat");
     if (!datafile)
      cout<<"Error";
      else
      {
         cout<<" This is the data for June, July, August. "  << endl<<endl;
          cout<< "MONTH 0 = JUNE,MONTH 1 = JULY, MONTH 2 = AUGUST"<< endl<<endl;
         for(month = 0; month < NUM_MONTHS ; month++)
          { for (count =0; count < NUM_DAYS ; count++)
              {
                       cout << " MONTH " <<(month)
                            << ",DAY " << (count+1) << " : ";
                      datafile >> rainorshine[month][count];
                      cout << rainorshine[month][count] << endl;
                       }
              cout<<endl;
              }
              }

The output is like this:

Code:

MONTH 0, DAY1 : S
.........................              // MONTH 0 means JUNE.
.........................
.........................
MONTH 0, DAY 30 : C

MONTH 1, DAY1 : R
.........................
.........................           //MONTH 1 means JULY
.........................
MONTH 1, DAY 30 : S

MONTH 2, DAY1 : S
.........................
.........................               //MONTH 2 means AUGUST
.........................
MONTH 2, DAY 30 : C

From now what I need to find out is 1.how many rainy, cloudy, sunny days in each month and whole 3 month period?
2. which of the 3 months had the largest number of rainy days.
