@Maddy Do you mean in Qt? QtCreator is an IDE.
if (listWidget->item(1)->text() == someString) -

Yes in IDE .main.cpp:56:33: Result of comparison against a string literal is unspecified (use an explicit string comparison function instead) his error is coming

Don't you think you should post the code which causes this error?
"Yes in IDE" - your question has nothing to do with the IDE...

Hi,
Extract the items in a list, shuffle that list and re-insert the items.
Another way is to use a QListView with a QStringListModel. Shuffle your string list and apply it to the model once done.

- Pick a random word and pass it to void QListWidget::addItem(const QString &label)..
- Or, pick a number of random words, put them in a
QStringListand pass that to void QListWidget::addItems(const QStringList &labels).

- Get/choose your source with words in it. I do not know what you intend to do for that.
- Assuming they are in some vector/array. Generate a random integer (Qt has QRandomGenerator Class) between 0 and 1 less than the count of words.
- Pick that word via
vect[random_int].

"Task 1(RandomWord):" fonts(x)is not a legal expression in C++.

Please read documentation and learn how to create strings (https://doc.qt.io/qt-6/qstring.html). Also, learn C++.
And please explain what exactly "fonts" is. -

is the answer. If you already have a
QStringList("the fonts is qstringlist ") then pass that toaddItems().Your earlier
ui->listWidget_2->addItems("Task 1(RandomWord):" fonts(x));passes
"Task 1(RandomWord):" fonts(x), which is neither a legal C++ expression, nor if it were would it be a list (QStringList), which is what you say you want to pass and whataddItems()accepts. If you say you want to add a list and are going to calladdItems()then there is not much point trying to pass it something like a single item....
