#include<stdio.h>
void main()
{
char a[8] = {1,20,30,40,50,60,70,80};
char * p =a;
int c = 0x12345678;
char d = 0xee;
char *p1 = &c;
char *p2 = &d;
printf("%x\n",a);
printf("%x\n",p);
printf("%x\n",p+1);
printf("%x\n",p+2);
printf("****************\n");
printf("C address = %x\n",&c);
printf("D address = %x\n",&d);
printf("%x\n",*p1);
printf("%x\n",*(p1+1));
printf("%x\n",*(p1+2));
printf("%x\n",*(p1+3));
printf("%x\n",d);
printf("%x\n",*(p1-1));
}
它的输出结果是这样的:
先不考虑这代码是否合理
我想不通啊,*(p1+1)与*(p1-1)没什么不同啊,为啥输出的结果却完全不一样啊,按我的推测,它应该输出的是一个8bit数据,但*(p1-1)输出的却是32位的数据.所以想不通啊.
