c++ 如何获取系统时间的前两个星期的时间

#include #include #include using namespace std; int getSystemTime() { time_t timer; time(&timer); tm* t_tm = localtime(&timer); cout

//方案— 优点:仅使用C标准库;缺点:只能精确到秒级 #include #include int main( void ) { time_t t = time(0); char tmp[64]; strftime( tmp, sizeof(tmp), "%Y/%m/%d %X %A 本年第%j天 %z",localtime(&t) ); puts( tmp ); return 0; } size_...

//方案— 优点:仅使用C标准库;缺点:只能精确到秒级 #include #include int main( void ) { time_t t = time(0); char tmp[64]; strftime( tmp, sizeof(tmp), "%Y/%m/%d %X %A 本年第%j天 %z",localtime(&t) ); puts( tmp ); return 0; } size_...

在VC的MFC中可以使用 CTime time = CTime::GetCurrentTime(); ///构造CTime对象 CString m_strTime = time.Format("%Y-%m-%d %H:%M:%S"); //将获得的时间以年-月-日 时:分:秒的形式保存到m_strTime 字符串变量中,如果你需要保存到文本中,就...

// system_clock example#include #include #include #include int main (){ using std::chrono::system_clock; std::chrono::duration one_day (1); system_clock::time_point today = system_clock::now(); system_clock::time_point tomorrow...

#include #include #include int main(){ for(;;) { time_t nowTime = time(NULL); struct tm *t = localtime(&nowTime); printf("\r%d-%02d-%02d %02d:%02d:%02d", t->tm_year + 1900, t->tm_mon + 1, t->tm_mday, t->tm_hour, t->tm_min, t->t...

#include #include #include int main(int argc, char *argv[]) { time_t curtime = time(NULL); tm *ptm = localtime(&curtime); char buf[64]; sprintf(buf, "%d/%02d/%02d %02d:%02d:%02d", ptm->tm_year+1900, ptm->tm_mon+1, ptm->tm_mday,...

#include #include #include void main () { time_t rawtime; struct tm * timeinfo; time ( &rawtime ); timeinfo = localtime ( &rawtime ); printf ( "\007The current date/time is: %s", asctime (timeinfo) ); //exit(0); int year,month,...

方法如下: time_t curtime = time(0); tm tim; localtime_s(&tim, &curtime); char title[128]; static int s_num = 0; sprintf(title, "%d/%02d/%02d %02d:%02d:%02d", tim.tm_year+1900, tim.tm_mon+1, tim.tm_mday, tim.tm_hour, tim.tm_min...

#include CTimeSpan time;CTime t1(2015, 2, 19, 0, 0, 0); //起始时间SYSTEMTIME tt;GetLocalTime(&tt); //获取当前系统时间CTime t2(tt);time = t2 - t1; //时间差CString t_str; //显示时间差到界面t_str.Format(_T("%d"), time.GetDays());G...
