自用电脑温度报警

描述：

　　最近发现电脑风扇有时候不转！散热口那会烫的厉害!拆开后盖后可能是风扇接线接触不良！写个程序监控一下CPU的温度！

1. windows控制台程序。 每2分钟采一次温度数据，如果温度高于60,70,80,90(不大可能)时分别响警报声2,4,6,8次；温度高于60，70时采集频率加倍，控制台打印字体显黄色；变成1分钟采一次，高于80的时候30秒采一次，控制台打印字体显示红色；

2. 加入windows自启动。



代码：

　　新建temptest.cpp。加入如下代码。

　　报警声用cout<<"\a";也可以换成自己想要的铃声。

// temptest.cpp : 定义控制台应用程序的入口点。

加入开机启动项，将程序拖到C:\Users\zhu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup文件中，zhu换成自己的用户名

或写成bat放入。
