Thread: constant integer class variable errors

You might try something like this:

Code:

    int rn;
    std::string name, ccnum;

    std::ifstream fin("input.txt");
    if (!fin) {
        std::cerr << "Error ...\n";
        std::exit(EXIT_FAILURE); // you may want to exit, or not...
    }

    while (fin >> rn) {
        fin >> name;  // Can the name have spaces? Then this won't work.
        fin >> ccnum;
        // With the appropriate Customer ctor you could do this:
        hotel.room[rn].assignCustomer(Customer(name, ccnum));
        // If hotel.room is a vector, you're better to use at() instead of [].
    }

If room is a vector, then you should consider using push_back. Depending on whether you want rooms to exist without customers, either solution may be preferable.
