How to increment a counter in qt?

Question

Qt

There is a code

int page = 0;
    int count = 2;


    if (ui->lineEdit->text().toDouble() == answers[page].getA())
    {
        ui->textBrowser_2->clear();
        ui->textBrowser_2->append(tasks[page+1]);
        QString str = QString::number(count);
        ui->label->setText(QString(str + "/5"));
        wins++;
    }
    else
    {
        ui->textBrowser_2->clear();
        ui->textBrowser_2->append(tasks[page+1]);
        QString str = QString::number(count);
        ui->label->setText(QString(str + "/5"));
        fail++;
    }
    page++;
    qDebug() << page;
}

this is a slot called when the button is clicked. How can I make the page variable increase with each click?

Answer 1

At a minimum, you need to make page and count fields of the class.

Answer 2

Qt has absolutely nothing to do with it, you fundamentally do not understand what a scope is, there will be similar problems in any language.
