計算週別( for VC6 )

VC6如果要計算出現在日期的週數(week number)，可用strftime來達成

/* example */

#include < stdio. h >
#include < time. h >

int main ()
{
time_t rawtime;
struct tm * timeinfo;
char buffer [255];

time ( &rawtime );
timeinfo = localtime ( &rawtime );

strftime (buffer,255,"今天是西元%Y年%B, %d 第%W週, 現在時間是%H：%M：%S" ",timeinfo);

return 0;
}
