Array question

[PaceyIV]

You define the int myArrayOne[44][3]; in the class header, so in the constructor you don't have to re-define myArrayOne.
myArrayOne defined in the constructor is a private variable visible only in the constructor. It is different from the one defined in the class as private member.

try

holdingWidget::holdingWidget(QWidget* parent): QWidget(parent)
{
    for (int r=0; r < 44; ++r)
        for (int c=0; c<3; ++c)
               myArrayOne[r][c] = 1;
 
 
}

holdingWidget::holdingWidget(QWidget* parent): QWidget(parent)
{
    for (int r=0; r < 44; ++r)
        for (int c=0; c<3; ++c)
               myArrayOne[r][c] = 1;
