Question

C++ 如何从系统获取当前时间，要年月日，不要小时，分钟，秒的。

Answer 1

CTime m_currentTime=CTime::GetCurrentTime();
int m_year;
int m_month;
int m_day;
char CurrentTime[128];

m_year=m_currentTime.GetYear();
m_month=m_currentTime.GetMonth();
m_day=m_currentTime.GetDay();

sprintf(CurrentTime,"%04d年%02d月%02d日",m_year,m_month,m_day);

Answer 2

#include<iostream>
#include<time.h>
#include<windows.h>
using namespace std;
int getSystemTime()
{
time_t timer;
time(&timer);
tm* t_tm = localtime(&timer);

cout<<"today is "<<t_tm->tm_year+1900<<" "<<t_tm->tm_mon+1<<" "<<t_tm->tm_mday<<endl;
return 0;
}

int main()
{

getSystemTime();
return 0;
}

Answer 3

CTime类有一个静态函数GetCurrentTime();
然后使用Format
