class QxRSSScheduleItem
{
public:
QxRSSScheduleItem( QxRSSFeeds::QxRSSFeedRep * rep );
QxRSSScheduleItem( const QxRSSScheduleItem& copy);
QxRSSScheduleItem& operator=( const QxRSSScheduleItem& copy);
friend bool operator<( QxRSSScheduleItem& si1, QxRSSScheduleItem& si2 );
friend bool operator==(QxRSSScheduleItem& si1, QxRSSScheduleItem& si2 );
QxRSSFeeds::QxRSSFeedRep * rep();
static time_t cmp_time;
private:
void copyMembers( const QxRSSScheduleItem & copy );
QxRSSFeeds::QxRSSFeedRep * Rep;
};
the above is a class of which I have a number in a vector. how do I sort the
vector?
thanks

std::sort(vec.begin(), vec.end());

If you didn't have an operator< (of which I really wonder if it has any
natural meaning for that case) or if you want to sort it differently you
need to supply a predicate as third argument.
