看一下这段就知道了。
/*
* string.h declares one type and several functions, and defines one macro
* useful for manipulating character arrays and other objects treated as
* character arrays. Various methods are used for determining the lengths of
* the arrays, but in all cases a char * or void * argument points to the
* initial (lowest addresses) character of the array. If an array is written
* beyond the end of an object, the behaviour is undefined.
