    Code:
    for ( y = 1900 ; y < inputyear ; y++ ) {
        // do something
    }
    Without leap years, the first day of January each year advances by one day.
    So 1/1/1900 was Monday, so 1/1/1901 was Tuesday.
    And so on until you've counted how many years you want to.

    Lightbulb C++ calendar

    So if i did:
    int calcDay(int month, int year)
    {
    int day=1;
    for(y=1900;y< year; y++)
    {
    if (isLeap(year))
    day = day + 366;
    else
    day = day = 365;
    day = day % 7;
    }
    }

    it should calculate the day from the input year right??

    while we're on the subject, i was wondering what more advanced programmers would think of this function
    Code:
    int daysInMonth(int year, int month)
    {
        Date temp(year, month, 1);
        switch(month)
        {
            case 2:
                if(temp.isLeap())
                    return 29;
                else
                    return 28;
            case 4:
            case 6:
            case 9:
            case 11:
                return 30;
            default:
                return 31;
                    
        }       
        return 0;
    }
    i seem to have GCC 3.3.4
    But how do i start it?
    I dont have a menu for it or anything.

    if it has to work for any year....

    To correct the calendar in 1582 10 days were arbitrarily omitted, 1582 October 4th being followed by 1582 October 15th.
