C++中的Timer组件虽然好用,却无法提供精确定时,只能精确到100毫秒左右,本程序中提供了一个定时工具,可精确到1毫秒,可用于参考执行定时循环任务-C++ in the Timer component although useful, but can not provide precise timing, can only be accurate to about 100 milliseconds, the program provides a regular tool accurate to 1 ms, can be used to refer to the implementation of tasks from time to time the cycle
