[Dev-C++] loop error

[Noorez K. <coo...@ho...>]

The marked loop keeps going on forever. Even if the condition in false

int main()
{
    cout << "Welcome to the quiz maker.\n";
    cout << "With this program you can make a Multiple Choice/True or False 
quiz.\n";
    cout << "We need the name of the quiz file: ";
    char* quizName = new char;
    cin.getline(quizName,123);
    strcat(quizName,".qz");
    cout << "If filename exists it will be overwritten\n";
    cout << "Continue [Y\\N]";
    char goOn;
    do//this loop
    {
        cin >> goOn;
        cin.sync();
        if(goOn == 'n' || goOn == 'N')
          return 0;
    }while(goOn != 'n' || goOn != 'N' || goOn != 'y' || goOn != 'Y');//keeps 
running even if goOn == 'y' || goOn == 'Y'

    cout << endl << "\nLets start making questions!\n";
    system("pause");
    system("cls");
    Quiz question;
    char contin;
    do
    {
        question = question.createQuestion();
        question.writeQuestion(question,Quiz::type,quizName);
        Quiz::questionNumb = Quiz::questionNumb+1;
        cout << "\nDo you want to add another question [Y\\N] ";
        do
        {
            cin >> contin;

        }while(!(contin == 'y' || contin == 'Y' || contin == 'n' || contin 
== 'N'));

    }while(contin == 'y' || contin == 'Y');
}
