A variable needs to be of some type..
you cannot simply write
xyz = something; You need to define what type of is xyz, is it int, QString, QWidget etc...

To answer your question of where to add it:

#ifndef BYTECONVERTERDIALOG_H
#define BYTECONVERTERDIALOG_H
 
#include <QDialog>
 
class byteConverterDialog : public QDialog
{
    Q_OBJECT
 
public:
    byteConverterDialog();
 
private:
    // <----------Here. 
};
 
#endif // BYTECONVERTERDIALOG_H

#ifndef BYTECONVERTERDIALOG_H
#define BYTECONVERTERDIALOG_H
 
#include <QDialog>
 
class byteConverterDialog : public QDialog
{
    Q_OBJECT
 
public:
    byteConverterDialog();

private:
    // <----------Here. 
};

#endif // BYTECONVERTERDIALOG_H
