谁知时间相加?高手,急急急.

即我想知道如何得出下个月的今天?

operator + – Add and subtract CTimeSpan and CTime objects.

[advancedchan]

// crt_mktime.c
/* The example takes a number of days
* as input and returns the time, the current
* date, and the specified number of days.
*/

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

int main( void )
{
struct tm when;
__time64_t now, result;
int days;

_time64( &now );
when = *_localtime64( &now );
printf( "Current time is %s\n", asctime( &when ) );
days = 20;
when.tm_mday = when.tm_mday + days;
if( (result = _mktime64( &when )) != (time_t)-1 )
printf( "In %d days the time will be %s\n",
days, asctime( &when ) );
else
perror( "_mktime64 failed" );
}
Sample Output
Current time is Tue Feb 12 09:57:44 2002

In 20 days the time will be Mon Mar 04 09:57:44 2002

获得当前的年、月、日...
月份+1。

首先你知道当前的月有几天，然后在当前时间上加上这个天数就行了

CTime tm = CTime::GetCurrentTime();
int day = tm.GetDay();
CTimeSpan ts = CTimeSpan(day,0,0,0);
tm += ts;

3Q各位,特别鸣谢38062708..已经解决了.

参考CTimeSpan类

自己做一个函数,把当前月份当参数传进来,做几个switch而已!

[hcfhhz]

自己做一个函数会很麻烦的,又要涉及年份,什么闰年,闰月都要考虑.如何有一个内部函数就好了.
