指针加1

对指针进行加1，其实就是加上其指向类型的大小。

struct B {

               long lA1;

               char cA2;

               char cA3;

               long lA4;

               long lA5;

       }*p;

       p = ( struct B *)0x1000000;

        //p + 0x1 = 0x100100;

        //(unsigned long)p + 0x1 = 0x100001;

        //(unsigned long*)p + 0x1 = 0x100004;

        //(char*)p + 0x1 = 0x100001;
