字符数组会自动扩容么？

If the destination string of a strcpy() is not large enough,  then  anything  might  happen.   Overflowing  fixed-length
       string  buffers is a favorite cracker technique for taking complete control of the machine.  Any time a program reads or
       copies data into a buffer, the program first needs to check that there’s enough space.  This may be unnecessary  if  you
       can  show  that  overflow  is  impossible, but be careful: programs can get changed over time, in ways that may make the
       impossible possible.

其实只是可能,栈这个跟编译器有很大关系的.....
非要弄成死循环的话,放到一个结构体内倒是必死无疑
