/*
File: Rainfall.cpp
Description: Write a program that reads in the average monthly rainfall for a city for each month
of the year and then reads in the actual monthly rainfall for each of the previous 12 months. The program
then prints out a nicely formnatted table showing the rainfall for each of the previous 12 months as well
as how much below or above average the rainfall was for each month. The average monthly rainfall is given
for months January-December in order. To obtain the actual rainfall for the previous 12 months, the program first
asks what the current month is and then asks for the rainfall figures for the previous 12 months.

After you have completed this program, produce an enhanced version that also outputs a graph showing the
acerage rainfall and the actual rainfall for each of the previous 12 months. Your program should also ask the
user whether they want to see the table or the graph. Include a loop that allows the user tos eee either format as
many times as they wish until they end the program.

My question is regarding if i should have the user input a file name they wish to output the information to within main or in another void function. Basically What is needed at this point is the user is asked to input a file name that they wish too save the information from the program to. IT is a user inputted file name, which is where I am confused

I strongly recommend that you first simplify the program thusly:

as how much below or above average the rainfall was for each month. The average monthly rainfall is given
for months January-December in order. To obtain the actual rainfall for the previous 12 months, the program first
asks what the current month is and then asks for the rainfall figures for the previous 12 months.

acerage rainfall and the actual rainfall for each of the previous 12 months. Your program should also ask the

    cout << endl;
}

This should make the whole thing a lot easier to work with.

Now, as for how to get the file names, it would seem fairly straightforward to simply get the filenames in main(), and then pass it to the function(s) which reads in the data (the one I now call read_data(), in this case).

[VernonDozier]

>> My question is regarding if i should have the user input a file name they wish to output the information to within main or in another void function

Either will work. My general preference in these things is to use a function. It really doesn't matter. I don't see any attempt to do either. I guess you are going to change it so that "rainfall_current.dat" and "rainfall_previous.dat" are no longer hard-coded, but are instead user-entered. Is that the task?

As for the question you didn't ask, but I'll commnet on anyway, you have twelve chunks of repeated code, one for each month. Surely you can change this to one chunk of code and substitute an array index. The code will look much cleaner.

[iGuardian]

What it is, is I need to output the information to a new file with a user defined name. Basically I give them the option to output the info to a file and then they name the new file they wish to name it. Here's what I have

cout << "Would you like to output this info to a file? ( A-Yes, B-No )" << endl;
        cin >> answer1;

        while ( answer1 == 'Y' || answer1 == 'y' )
        {
        string file_name; // strings are better to use than char
        ofstream ofile;

        cout << "What would you like to call your file? ";
        cin >> file_name;

        ofile.open(string(file_name+".txt").c_str()); // will make a file named after the user and save it as a text fil

        ofile.close();

        return 0;
        }

I keep running into a seg fault as well.

[ndeniche]

If you're promting the user to enter a filename to which you'll save the information, I'd recommend you ask for it in a separate function, since reading it from the main() function means sending the parameters when executing the program, either from a shortcut link or a shell call from another program.

Just use a function prompting the user (via printf or cout) to enter a filename.

[Schol-R-LEA]

Actually, passing the filenames by command line might be the best solution of all:

Just curious, I had tried your code and I got "usage: rainfall <current_datafile> <previous_datafile> <output_file>

Process returned 255 (0xFF) execution time : 0.003 s
Press ENTER to continue."

What exactly is going on there?

void ( ofstream& outfile )
{
    cout << "Would you like to output this info to a file? ( A-Yes, B-No )" << endl;
    cin >> answer1;

    while ( answer1 == 'Y' || answer1 == 'y' )
    {
        char file_name; // strings are better to use than char
        ofstream ofile;

        cout << "What would you like to call your file? ";
        cin >> file_name;

        ofile.open(char(file_name+".txt").c_str()); // will make a file named after the user and save it as a text fil

        ofile.close();

    return 0;
    }
}

Does this look better? Also I get an error "Expected ')' before token '&'"

The version of the program I wrote requires command-line arguments. If you are using Code::Blocks (which I gather is the case), you can go to the Project menu and select Set Programs' Arguments to add the filenames: rainfall_current.dat rainfall_previous.dat rainfall_totals.dat When this is run, it should create a file named rainfall_totals.dat which will contain the generated tables.

Thank you for the help, finally got it.
Here's the final code. Thanks again.

/*
File: Rainfall.cpp (Version 3)
Description: Write a program that reads in the average monthly rainfall for a city for each month
of the year and then reads in the actual monthly rainfall for each of the previous 12 months. The program
then prints out a nicely formnatted table showing the rainfall for each of the previous 12 months as well
as how much below or above average the rainfall was for each month. The average monthly rainfall is given
for months January-December in order. To obtain the actual rainfall for the previous 12 months, the program first
asks what the current month is and then asks for the rainfall figures for the previous 12 months.

After you have completed this program, produce an enhanced version that also outputs a graph showing the
acerage rainfall and the actual rainfall for each of the previous 12 months. Your program should also ask the
user whether they want to see the table or the graph. Include a loop that allows the user tos eee either format as
many times as they wish until they end the program.

For a more elaborate version, also allow the user to request the table be output to a file of which the name is
entered by the user. This program does everything that version 1 does.

This version is like version 1 except that input is taken from a file and the output is sent to a file. There is no user to interact
with, so there should be no loops to loop the program.
