Question

Can anyone tell me what is “j” and “i” in this .cs code?

private void zoom_out(object sender, RoutedEventArgs e)
    {
        if(j>0)
        {
            image1.Height -= 50;
            image1.Width -= 50;
            j--;
            i = j;
        }
    }
private void zoom_in(object sender, RoutedEventArgs e)
    {
       if(i<2)
        {
            image1.Height += 50;
            image1.Width += 50;
            i++;
            j = i;
        }
    }

And change “j” and “i” for .vb code. It is code for zooming out and in.

I believe they are a programming concept most commonly termed ‘variables’. They are used to store application state and perform computations.
