在Linux环境下，用C语言每隔三秒建立一个以日期时间命名的文件

Answer 1

具体实现的步骤如下：

time_t now;
struct tm *curTime;

char filename[256];
while(1)
{
now = time(NULL);
curTime = localtime(&now);
sprintf(filename,"%04d-%02d-%02d %02d-%02d-%02d",curTime->tm_year+1900,
curTime->tm_mon+1,curTime->tm_mday,curTime->tm_hour,curTime->tm_min,
curTime->tm_sec);
fp = fopen(filename,"w");
fclose(fp);
sleep(3);
}

Answer 2

time_t now;
struct tm *curTime;

char filename[256];
while(1)
{
   now = time(NULL);
   curTime = localtime(&now);
   sprintf(filename,"%04d-%02d-%02d %02d-%02d-%02d",curTime->tm_year+1900,
        curTime->tm_mon+1,curTime->tm_mday,curTime->tm_hour,curTime->tm_min,
        curTime->tm_sec);
   fp = fopen(filename,"w");
   fclose(fp);
   sleep(3);
}
