若我们用[0x9999]来标记内存地址，则 *[0x9999]表示该地址内存中存储的数值
变量
int a;
a *[0x9999] 1
&a [0x9999]
指针
int* a;
a *[0x8888] [0x9999]
*a *(*[0x8888]) *[0x9999] 1
&a [0x8888]
结构体变量
struct mystruct
{
int a; [0x9991]
int b; [0x9992]
int c; [0x9993]
}s;
s *[0x9991] 1
&s [0x9991]
s.a *[0x9991] 1
&s.a [0x9991]
结构体指针变量
struct mystruct
{
int a; [0x9999]
int b; [0x999A]
int c; [0x999B]
};
struct mystruct* s;
s *[0x8888] [0x9999]
*s *(*[0x8888]) *[0x9999] 1
&s [0x8888]
s->a *(*[0x8888]) *[0x9999] 1
&s->a [0x9999]
*s->a none
数组(很奇怪)
int a[];
&a [0x9999]
a [0x9999]
*a *[0x9999] 1
a[0] *[0x9999] 1
&a[0] [0x9999]
结构体数组(很奇怪)
struct mystruct
{
int a; [0x9999]
int b; [0x999A]
int c; [0x999B]
};
struct mystruct s[];
s[0].a *[0x9999] 1
s[0] *[0x9999] 1
&s[0] [0x9999]
s [0x9999]
*s *[0x9999] 1
&s [0x9999]
