Question

VC 6.0下编写的的控制台程序（就是只有黑底白字窗口的那个）。有什么自带函数能载入系统当前时间吗？

VC 6.0下编写的的控制台程序（就是只有黑底白字窗口的那个）。有什么自带函数能载入系统当前时间吗？

Answer 1

是要打印时间？
system("time");
如果是要在程序中获取的话，可以类似这样：
typedef union
{
struct
{
int16 year;
int8 month;
int8 mday;
int8 hour;
int8 minute;
int8 second;
int8 wday;
};
uint64 uint64val;
} OSTime;

OSTime OSTimeCurTime()
{
OSTime t = {0};
time_t ct = time(NULL);
struct tm ctm;

memcpy(&ctm, localtime(&ct), sizeof(ctm));
t.year = ctm.tm_year + 1900;
t.month = ctm.tm_mon + 1;
t.mday = ctm.tm_mday;
t.hour = ctm.tm_hour;
t.minute = ctm.tm_min;
t.second = ctm.tm_sec;
t.wday = ctm.tm_wday;

return t;
}

就是把系统时间的年月日分别存入变量year，month，day中。您给的代码有点复杂了。您能否帮忙把楼下的代码改成把系统时间的年月日分别存入变量year，month，day的形式，谢谢

#include

void main()
{
int year,month,day;
int hour,minute,second;
time_t ct = time(NULL);
struct tm ctm;

memcpy(&ctm, localtime(&ct), sizeof(ctm));
year = ctm.tm_year + 1900;
month = ctm.tm_mon + 1;
day = ctm.tm_mday;
hour = ctm.tm_hour;
minute = ctm.tm_min;
second = ctm.tm_sec;

printf("当前时间:%4d年%2d月%2d日 %2d:%2d:%2d\n",year,month,day,hour,minute,second);
}

Answer 2

void GetSystemTime(
LPSYSTEMTIME lpSystemTime
);
Parameters

lpSystemTime
[out] Pointer to a SYSTEMTIME structure to receive the current system date and time.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Winbase.h.
Link Library: Coredll.lib.

void GetLocalTime(
LPSYSTEMTIME lpSystemTime
);
Parameters

lpSystemTime
[out] Pointer to a SYSTEMTIME structure to receive the current local date and time.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Winbase.h.
Link Library: Coredll.lib.

Answer 3

//下面的程序在VC6上验证ok，你试试：

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

int main()
{
time_t nowtime;
nowtime=time(NULL);
struct tm *local;
local=NULL;
local=localtime(&nowtime);
char *buffer=new char[12];
strftime(buffer,128,"%c",local);
printf("%s\n",buffer);

return 0;
}

您好，请问。如果我只要年月日。并分别存到变量year，month，day中。这段代码该如何改？谢谢

int main()
{
time_t ct = time(NULL);
struct tm ctm;
int year,month,day;

memcpy(&ctm, localtime(&ct), sizeof(ctm));
year = ctm.tm_year + 1900;
month = ctm.tm_mon + 1;
day = ctm.tm_mday;

printf("year: %d,month: %d,day: %d\n",year,month,day);

return 0;
}
