Question

I’m working on a project that requires that input must be taken from a file and then processed. We were given a skeleton of the code for opening a file and checking to make sure it is open, but I’m having issues opening the file.

My Code

int main()

{
    readFile();
}

void readFile()
{
    ifstream fin;
    string fileName;
    int x;

    cout << "Enter the file you wish to read from: ";
    cin >> fileName;

    fin.open(fileName.c_str(), ios::in);

    if(!fin.is_open())
    {
        cerr << "Unable to open file " << fileName << endl;
        exit(10);
    }
}

My console:

We were basically given all of this code so I have absolutely no idea why this isn’t working out. This is just a part of my much larger project but I can’t even attempt that part yet until I get this working. Any help would be much appreciated.

Probably your directory settings don’t show the files extension. You need to enter 12.txt.txt instead of 12.txt.
