C语言或其开机时间与控制台电子时钟

printf("已经开机：%d分钟/n",GetTickCount()/1000/60);

一句代码而已，呵呵。

time_t m_time;
	time(&m_time);
	tm* tm_local=localtime(&m_time);
	while(1)
	{
		clrscr();
		printf("已经开机：%d分钟/n",GetTickCount()/1000/60);
		time_t m_time;
		time(&m_time);
		tm* tm_local=localtime(&m_time);
		gotoxy(0,2);
		printf("%d:%d:%d %d:%d:%02d/n",tm_local->tm_year+1900,tm_local->tm_mon+1,tm_local->tm_mday,tm_local->tm_hour,tm_local->tm_min,tm_local->tm_sec);
		Sleep(200);
	}
	getchar();
