當使用memset的時候，初始化的數據如下：134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 134744072 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

該問題主要自身對memset的理解不夠透徹。
NAME memset - fill memory with a constant byte SYNOPSIS #include <string.h> void *memset(void *s, int c, size_t n); DESCRIPTION The memset() function fills the first n bytes of the memory area pointed to by s with the constant byte c.
code中alphabet定義的是int而非char，它只是初始化前n byte，而不是4*n byte。
