There are so many ways that you will need to be a bit more precise on what you need.

i want to code a merge sort algorithm, but just to start i want to display for example a QVector of 10 elements, just for the interface
i want to display this vector

#include <QApplication>
#include <QtWidgets>
 
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QWidget f;
    QVector<int> vector(5);
    for (int i=0;i< vector.size(); i++)
    {
        vector[i]=i;
    }
 
 
 
 
    f.show();
    return app.exec();
 
}

#include <QApplication>
#include <QtWidgets>


int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QWidget f;
    QVector<int> vector(5);
    for (int i=0;i< vector.size(); i++)
    {
        vector[i]=i;
    }




    f.show();
    return app.exec();

}

To copy to clipboard, switch view to plain text mode

The easiest way I can think of is to create a string that contains all numbers and display that in a QLabel

QStringList items;
foreach (const int number, vector) {
    items << QString::number(number);
}
label->setText(items.join(", "));

QStringList items;
foreach (const int number, vector) {
    items << QString::number(number);
}
label->setText(items.join(", "));

To copy to clipboard, switch view to plain text mode 

Alternatively with a QListWidget

foreach (const int number, vector) {
    listWidget->addItem(QString::number(number));
}

foreach (const int number, vector) {
    listWidget->addItem(QString::number(number));
}
