Question

My IDE is having issues with the “filename” variable on the last line. Can someone point out to me why?

    switch(filename_selection)
    {
        case 1: filename_selection = 1;
        filename = "foo3.sql";
        break;

        case 2: filename_selection = 2;
        filename = "foo2.sql";
        break;

        case 3: filename_selection = 3;
        filename = "foo1.sql";
        break;

        default:
        cout << "Invalid selection." << endl;
        break;
    }
    ofstream File;
    File.open(filename, ios::out | ios::trunc);

My crystal ball is a bit cloudy today, but I think I can see something…

Your filename is declared as std::string filename;. Sadly, in C++03, std::(i|o)fstream classes didn’t have constructors that accept std::string variables, only char const* ones.

Solution: Pass filename.c_str().
