The following example calls the IsLeapDay method for the last day of the second month (February) for five years in each of the eras.
using namespace System; using namespace System::Globalization; int main() { // Creates and initializes a HijriCalendar. HijriCalendar^ myCal = gcnew HijriCalendar; // Creates a holder for the last day of the second month (February). int iLastDay; // Displays the header. Console::Write( "YEAR\t" ); for ( int y = 1421; y <= 1425; y++ ) Console::Write( "\t {0}", y ); Console::WriteLine(); // Checks five years in the current era. Console::Write( "CurrentEra:" ); for ( int y = 1421; y <= 1425; y++ ) { iLastDay = myCal->GetDaysInMonth( y, 2, HijriCalendar::CurrentEra ); Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, HijriCalendar::CurrentEra ) ); } Console::WriteLine(); // Checks five years in each of the eras. for ( int i = 0; i < myCal->Eras->Length; i++ ) { Console::Write( "Era {0}:\t", myCal->Eras[ i ] ); for ( int y = 1421; y <= 1425; y++ ) { iLastDay = myCal->GetDaysInMonth( y, 2, myCal->Eras[ i ] ); Console::Write( "\t {0}", myCal->IsLeapDay( y, 2, iLastDay, myCal->Eras[ i ] ) ); } Console::WriteLine(); } } /* This code produces the following output. YEAR 1421 1422 1423 1424 1425 CurrentEra: False False False False False Era 1: False False False False False */
