VC定时器的问题

[coffeeroy2]

z在VC里想用定时器每隔1s取一个值，当前后两次的取值的差大于100时，执行相应的操作。请问该怎么做，能贴上代码么？求前辈指教，新手感激不尽~

#include <stdio.h>
#include <windows.h>

int main(int argc, char* argv[])
{
	int sleepCount = 0;
	int pre = 0;
	int num = 0;
	printf("Hello World!\n");
    while(1)
    {
		scanf("%d", &num); // 取值
		if (pre - num > 100 || num - pre > 100)
		{
			printf("do something.\n");
		} 
		else
		{
			printf("congtinue.\n");
		}
		
		Sleep(1000); // 等待1秒
    } // while(1);
	
	
	return 0;
}

这样行不行？

你是新手吧。首先你写的那个是个死循环，其次线程休眠和定时器是不同的

你是新手吧。首先你写的那个是个死循环，其次线程休眠和定时器是不同的[/quote] 嗯。向各位学习。
