linux下怎样用c语言编写一个时钟
我希望你只是需要如何知道时间，而不是写你一个时钟程序，那个太复杂了，如果只是想如何知道时间-
#include stdio.h
#include time.h
int main(void)
{
struct tm *tm_ptr;
time_t the_time;
(void)time(the_time);
tm_ptr=localtime(the_time);
printf("Date: %04d/%02d/%02d\n",
1900+tm_ptr-tm_year,tm_ptr-tm_mon+1,tm_ptr-tm_mday);
printf("Time: %02d:%02d:%02d\n",
tm_ptr-tm_hour,tm_ptr-tm_min,tm_ptr-tm_sec);
return(0);
}
