#includeIn this example, we create a QDate object for December 25, 2021 using the constructor that takes in year, month, and day as arguments. We then call the QDate.weekNumber() method on this object to obtain the week number for that date, which is stored in the integer variable weekNumber. Finally, we use qDebug() to output the week number to the console. Package Library: Qt Core Library#include int main() { QDate date(2021, 12, 25); // Create a QDate object for December 25, 2021 int weekNumber = date.weekNumber(); // Get the week number for December 25, 2021 qDebug() << "Week number for December 25, 2021: " << weekNumber; // Output the week number return 0; }
