【c语言】关于+1的各种情况

// 关于+1的各种情况#include <stdio.h>//默认对齐数为4// 结构体大小为16struct BBB{long A1;char A2;char A3;long A4;long A5;};int main(){struct BBB *p;p = (struct BBB *)0x100000;printf("%x\n", p + 0x1);//p是结构体指针，加1加了一个结构体大小，即0x100010printf("%x\n",(unsigned long) p + 0x1);// p是无符号长整型，加1即加1，即0x100001printf("%x\n", (unsigned long *)p + 0x1);// p是无符号长整型指针，加1即加一个指针大小4，即0x100004printf("%x\n",(char *)p + 0x1);// p是字符指针，加1即加字符指针大小1，即0x100001return 0;}
