Modify the GetDay function as follows, which forces the user to type a valid day:

int GetDay(int year, int month) 

{ 

    int day = 0; 

    int maxDay; 

 

    // Calculate maxDay, as before (code not shown here) … … … 

 

    do 

    { 

        Console::Write("Day [1 to "); 

        Console::Write(maxDay); 

        Console::Write("]? "); 

        String ^input = Console::ReadLine(); 

        day = Convert::ToInt32(input); 

    } 

    while (day < 1 || day > maxDay); 

    return day; 

}
