推荐答案

如果您使用的是MFC，则可以使用:

If you are using MFC then you can use:

int GetDays( int endYear, int endMonth, int endDay,
                    int begYear, int begMonth, int begDay )
{        
    CTime beg(begYear, begMonth, begDay, 0, 0,0 );
    CTime end(endYear, endMonth, endDay, 0, 0,0 );

    CTimeSpan dist = end - beg;

    return dist.GetDays();
}

否则，这可以为您提供帮助:

or otherwise, this could help you:

struct tm date1;
struct tm date2;

memset ( &date1, 0, sizeof ( struct tm));
memset ( &date2, 0, sizeof ( struct tm));

date1.tm_mday = 13;
date1.tm_month = 6;
date1.tm_year = 2003;

date2.tm_mday = 14;
date2.tm_month = 3;
date2.tm_year = 2004;

time_t time1, time2;

time1 = mktime ( &date1);
time2 = mktime ( &date2);

double dSecs = difftime ( time2, time1);

double dDays = dSecs / ( 3600.0 * 24);
