help with write to .txt file

[justutiz]

Hi everyone,
need some help, this function doesnt work for me and I dont know why, maybe you can help me.

void menu4(double array[], int n) {
    ofstream results("results.txt"); 
    for (int i = 0; i < n ; i++)
    {
        results << array[i] << " ";
        cout << array[i] << endl;
    }
    results << endl;
}

'cout' is printing the array elements, but in file i dont see nothing

You're not closing the output file. I wouldn't bet on the data being written out properly without that.

The closes "automatically" when the ofstream object goes out of scope.

Oh, thanks. I'll try to memorize tha now.

So I think first the OP should check whether the file gets opened correctly at all before writing to it. Perhaps there's some sort of permission issue?
