    How do I clear ifstream!?

    I am trying to write a simple spell checking program but no matter what I do it will only read through the word list once and all other times it just thinks it is the end of the file and does a check for the first word I put in...

    Here is the code:
    Code:
    while (repeat==true) {
            word_list.clear();
            word_list.seekg(0, ios::beg);
            cout << "\n\nType word here (lowercase): ";
            cin  >> input;
            system("clear");
                while (!word_list.eof()) {
                    word_list >> read;
                    cout << "\nTrying: " << read;
                    if (read==input) {
                        system("clear");
                        cout << " is a word!\n\n";
                        repeat=true;
                        //word_list.close();
                        word_list.clear();
                        word_list.seekg(0, ios::beg);
                        break;
                    }
                    else{
                        check0=1;
                    }
                }
                if (read!=input) {
                    system("clear");
                    //word_list.close();
                    word_list.clear();
                    word_list.seekg(0, ios::beg);
                    cout << "\n\n" << input << " is not a word!\n\n";
                }
                
            }
    EDIT: Resolved: removing word_list.close() fixed the issue
    I attached the full cpp file for reference...

    You are actually closing the file at various places in your code (when a word is matched, or when it is not). Any subsequent operation (seekg, reading, testing eof) will indicate an error condition.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Sunshine, and read this, this, and this before posting again.

    Thank you, I see that it was stupid to close the files without re-opening them. I just got rid of the close() operators and it works perfectly now. Once again thanks...
