Empty Output Array file

[bebu]

I am writing this program that is supposed to read a file, put the data into an array, alphabetize, count how many times each word appears and print to an output function. I posted before on how my program had an error when I ran it but I have fixed that. Now my outputArray file is empty. It gets created but there's nothing in it. I have been starting at this for hours and my mental capacity is wearing down. Any help is appreciated

Probably the first thing to do is make sure you are actually opening the input file.

//return false if cannot open file
bool openFile(ifstream& myfile, const std::string& myFileName)
{
    myfile.open(myFileName.c_str()); //look over this
    return myfile.is_open();
    // return true;
}

I'm pretty sure I'm doing that in my int main() when I have cout<<line it prints the file

That's a good sign.

Can you explain to me:

bool displayDataArray(const std::string &OUTPUTFILENAME)
{
    ofstream Output(OUTPUTFILENAMEARRAY);
    for (int m = 0; m < arraysize; m++)
    {
        if (!(listOfWords[m].word == " " || listOfWords[lastIndexof].number_occurences == 0))
        {
            Output << listOfWords[m].word << ":" << listOfWords[m].number_occurences << '\n';
        }
        //TODO
    }
    return true;
}

Why is the loop conditional m<arraysize and what are you trying to accomplish with the if statement?
