//The _getch function reads a single character from the console without echoing.
//Function can not be used to read CTRL+Break.
//When reading a function key or an arrow key,
//_getch must be called twice; the first call returns 0 or 0xE0,
//and the second call returns the actual key code.

if (27==k) break;//按Esc键退出
