很实用的三极管资料，封装：TO-92,1.5A-very practical transistor, Compliant : TO-92, 1.5A

从输入文件如in.txt读取数据，经com1端口发送（自发自收），收到的内容存入输出文件如out.txt。 在按键后启动发送，并开始计时，发送完毕后，结束计时，并显示发送所花时间。

有n个整数，使其前面各数顺序向后移m个位置，最后m个数变成最前面的m个数 -There is a whole number n, the number of its previous order of the backward shift position m, and finally the number m of m into the top of the number of
