How to get number of a month?

[sulacco]

Hi, People. Does anybody know how to get number of days in
a certain month of a certain year? Looked all the way in MSDN but failed to find such function.
Tx.

int days_in_month ( int month ) {
    static int days[] = { 31, 28, 31, /* fill in the rest */ };
    return days[month-1];
}

Then implement a leap year function which tells you whether February should be 28 or 29 days long.

thank you, I did it much compex and damn worse.
Btw, so I have to implement it on my own after all.

How about leap years (29 days in Feb?

inline bool isLeapYear(int y)
{
  return y%4 == 0 && (y%100 != 0 || y%400 == 0);
}

int day_in_month(int month, int year)
{
   int d;
   ... // as in Salem's post
   d = days...
   if (month == 2 && isLeapYear(year))
       ++d;
   return d;
}
