进击的小白Day014——计时器（完结）

因为老师那边例会需要，今天就自己diy了一个简单的计时器。因为需要统计所有人所用的时间，因此依然需要用到链表，事实证明链表用的还是不够熟练，以后还得多写一写这方面的程序。

这个程序实现的主要功能是，多次计时，最后将所有人的时间汇总，并从小到大输出。

贴代码：

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <windows.h>
#include <conio.h>
#define MAX 100
#define NUM 20

1. 键入指定按键中断循环，不用scanf，下面语句是键入Esc来中断循环的

while (c != 27)
{
	statement
		if (kbhit())
		{
			c = getch();
		}
}
